Hi Qters,

When i configure qt-everywhere-opensource-src-5.9.0. using ubuntu virtual machine ,

the error occur :

the opengl functionality tests failed
You might need to modify the include and library search paths by editting QMAKE_INCLUDE_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform

I have install opengl :

sudo apt-get install build-essential
sudo apt-get install libgl1-mesa-dev
sudo apt-get install libglu1-mesa-dev
sudo apt-get install libglut-dev

Now i do not know how to

modify the include and library search paths by editting QMAKE_INCLUDE_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2

Can you provide any clues ?

Thanks in advance!
@liubbc Add -v to your configure call, then you will see what is really missing
how to add -v?
@vincent365 said in the opengl functionality tests failed:

how to add -v?

You are compiling Qt from source, right? The first step is to call configure. So, you need to add ‘-v’ flag there:
```
configure -v [other config options you use for building Qt, like -confirm-license -nomake examples etc.]
```
I suspect you miss some OpenGL stuff. Try calling:
```
sudo apt-get build-dep qt5-default
```

This output does not show the error message, please look for it.

Also, please don’t steal somebody else’s thread, your issue is probably unrelated to what liubbc wrote about.
saw similar issue, installed the following fixed it
```
libgl1-mesa-dev 
libglu1-mesa-dev
```
I know I am late , but others may be still looking, so anyway: please try adding -opengl desktop as a parameter. Worked for me.
I got this error when I didn’t have the ninja build system installed, and configure created the Makefile based build system. After installing ninja (the ninja-build package on Debian), it worked.

I am also getting same error while compiling qt-everywhere-src-5.12.12 on CetnOS 7
Tried to get more logs with ./configure -v option

I already installed : yum install mesa-libGL-devel mesa-libGLU-devel
Still same error

@KiranS Check the configure.log file — there must be more information than what you posted (compiler/linker call and the actual error message).
@jsulm checked config log which has multiple dependency errors:

to resolve it I installed below packages but no luck
```
libvkd3d-devel
kf5-kwindowsystem-devel
alsa-lib-devel
pcre2-devel
snappy-devel
```
@KiranS said in the opengl functionality tests failed:

but no luck

Still same errors?
I suggest to run configure from clean state (new build folder).
@jsulm Thank you for your help, errors disappeared after running configure in fresh directory.
I was also having that problem, but configure is indeed fine with OpenGL when run from a fresh directory (and after installing the relevant OpenGL package(s), I can’t recall which ones). Man, so much time wasted on such a simple fix.
Add -no-opengl to the configure command line option saves my life.

I’m trying to build an executable Qt-based program for Linux, and link Qt statically in the binary. According to the Qt docs, to do this I’m going to need to build Qt from source, starting with the commands:

cd /path/to/Qt
./configure -static -prefix /path/to/Qt

when I try this, I get a long bunch of output ending with:

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

Check config.log for details.

This isn’t the first time I had problems with OpenGL and Qt… when I built my program with dynamic linking (using binary Qt libs) I got a similar problem, which I solved by symlinking to libGL.so from /usr/lib.

The output from configure said to go and find the «mkspec» for my platform, so I looked at Qt/5.13.1/Src/qtbase/mkspecs/linux-g++-64 (I explicitly told it to use that platform with the -platform command). I rooted around and tried setting those envvars to various combinations of paths that seemed plausible, to no avail.

It also mentioned a config.log file. When I look in this file, I can see open GL mentioned only in this block:

Indeed pkg-config --print-errors --exists gl can’t find anything. No idea where it’s getting that /usr/include/libdrm path…

[SOLVED] Problem while building the Qt5 on Ubuntu 18.04

I’m trying to build Qt5 source code now. But no success yet.
Please review my steps and let me know any possible mistakes.

Download the Qt5 (ver5.10) source code

Code: Select all

sudo apt-get build-dep qt5-default git

cd qt5
git checkout 5.10
perl init-repository

Add a mali_hack (Line 90 in Qt 5.10 qtbase/src/platformsupport/eglconvenience/qxlibeglintegration.cpp)

Code: Select all

                 return visualId;
             }
+            //hack

First I’d suggest not using the «hack» line but instead using the Vendor line: if (vendor && (strstr(vendor, "Vivante") || strstr(vendor, "ARM"))) this much better than always forcing the system to use this return path.

If you check the output of the configure result you can see the following:

Code: Select all

  EGL .................................... no
  OpenVG ................................. no
  OpenGL:
    Desktop OpenGL ....................... no
    OpenGL ES 2.0 ........................ no
    OpenGL ES 3.0 ........................ no
    OpenGL ES 3.1 ........................ no
    OpenGL ES 3.2 ........................ no

This is normally the case if you do NOT have the mesa headers installed, QT is one of these applications that require both MESA and MALI installed side by side.

Most likely this section will give you quite some trouble as well:

Code: Select all

QPA backends:
  DirectFB ............................... no
  EGLFS .................................. no
  LinuxFB ................................ yes
  VNC .................................... yes
  Mir client ............................. no
  X11:
    Using system-provided XCB libraries .. yes
    EGL on X11 ........................... no
    Xinput2 .............................. yes
    XCB XKB .............................. yes
    XLib ................................. yes
    XCB render ........................... yes
    XCB GLX .............................. yes
    XCB Xlib ............................. yes
    Using system-provided xkbcommon ...... yes
    Native painting (experimental) ....... yes

It defines what backends should be used and what you want is EGL on X11 but by now the MALI code detection is upstream already and it will instead try to go for EGLFS or LinuxFB which means it bypasses X11.
I don’t remember what exactly I did, but I had to alter the configure script to make sure mali detection retuns NO as an answer or else it won’t use EGL on X11.

Also in most cases programs will use /usr/lib/arm-linux-gnueabihf/libGLESv2.so /usr/lib/arm-linux-gnueabihf/libGLESv1_CM.so and /usr/lib/arm-linux-gnueabihf/libEGL.so they don’t really care what’s in subfolders, unless the links I mentioned point directly to these libraries.

I will try to learn how Qtbase configuration detects the OpenGL ES capabilities with the strange mesa dependancies.
But it seems to be very hard to understand for me.

then maybe it’s the last sentence I said.
QT compiles tiny example applications and links them against the libraries I mentioned.
Linking = successful -> yes, else no

Code: Select all

# EGL Support
if [ "$CFG_EGL" != "no" ]; then
    if [ "$CFG_EGL" = "yes" ] && [ "$CFG_OPENGL" = "no" ]; then
        echo "EGL support was requested but OpenGL support is disabled."
        echo "Either disable EGL support or enable OpenGL support."
        exit 101
    fi

    if [ -n "$PKG_CONFIG" ] && $PKG_CONFIG --exists egl 2>/dev/null; then
        QMAKE_INCDIR_EGL=`$PKG_CONFIG --cflags-only-I egl 2>/dev/null | sed -e 's,^-I,,g' -e 's, -I, ,g'`
        QMAKE_LIBS_EGL=`$PKG_CONFIG --libs egl 2>/dev/null`
        QMAKE_CFLAGS_EGL="`$PKG_CONFIG --cflags egl 2>/dev/null` -fpermissive"
        QMakeVar set QMAKE_INCDIR_EGL "$QMAKE_INCDIR_EGL"
        QMakeVar set QMAKE_LIBS_EGL "$QMAKE_LIBS_EGL"
        QMakeVar set QMAKE_CFLAGS_EGL "`echo " $QMAKE_CFLAGS_EGL " | sed -e 's, -I[^ ]* , ,g;s,^ ,,;s, $,,'`"
    fi       # detect EGL support
    if compileTest qpa/egl "EGL" $QMAKE_CFLAGS_EGL $QMAKE_LIBS_EGL; then
        CFG_EGL=yes
        if compileTest qpa/egl-x11 "EGL-X11" $QMAKE_CFLAGS_EGL $QMAKE_LIBS_EGL; then
            CFG_EGL_X=yes
        else
            CFG_EGL_X=no
        fi
    elif [ "$CFG_EGL" = "yes" ]; then
        echo " The EGL functionality test failed; EGL is required by some QPA plugins to manage contexts & surfaces."
        [ -z "$PKG_CONFIG" ] && echo " Use of pkg-config is not enabled, maybe you want to pass -pkg-config?"
        echo " You might need to modify the include and library search paths by editing"
        echo " QMAKE_INCDIR_EGL, QMAKE_LIBDIR_EGL and QMAKE_LIBS_EGL in ${XQMAKESPEC}."
        exit 1
    else
        CFG_EGL=no
        CFG_EGL_X=no
    fi
fi

First they check with pkg-config if the library exists:

It returns 0 if true or 1 if not
If true, they get different environment variables:
include paths: pkg-config --cflags-only-I egl
libaries required for linking: pkg-config --libs egl
compiler flags: pkg-config --cflags egl

after that they compile example programs with the variables they just gathered:

Code: Select all

      if compileTest qpa/egl "EGL" $QMAKE_CFLAGS_EGL $QMAKE_LIBS_EGL; then
        CFG_EGL=yes
        if compileTest qpa/egl-x11 "EGL-X11" $QMAKE_CFLAGS_EGL $QMAKE_LIBS_EGL; then
            CFG_EGL_X=yes

Similar things are done for OpenGL and OpenGL ES.

Also you should make sure you pass the option that you want «es2» as OpenGL -opengl es2:

Code: Select all

elif [ "$CFG_OPENGL" = "es2" ]; then
    #OpenGL ES 2.0

    compileTestWithPkgConfig glesv2 unix/opengles2 "OpenGL ES 2.0" OPENGL_ES2
    if [ $? != "0" ]; then
        echo "The OpenGL ES 2.0 functionality test failed!"
        [ -z "$PKG_CONFIG" ] && echo " Use of pkg-config is not enabled, maybe you want to pass -pkg-config?"
        echo " You might need to modify the include and library search paths by editing"
        echo " QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in"
        echo " ${XQMAKESPEC}."
        exit 1
    fi

Or else it will always test for OpenGL first.

Hi odroid,

To build qmake

Code: Select all

odroid@odroid:~/qt5/qtbase$ ./configure -v -prefix "/home/odroid/qt5/build" -release -confirm-license -opensource -platform linux-g++ -opengl es2 -no-pch -make libs  &> config_option

As per your suggestion here is the patch for qmake.
attach is the

I think your patch is missing an opening bracket on the vendor line.

Also here’s an excerpt from your config_options.txt:

Code: Select all

 => source failed verification.

You can see it’s trying to link against -lGLESv2 and fails as it says: /usr/lib/gcc/arm-linux-gnueabihf/7/../../../arm-linux-gnueabihf/libGLESv2.so: No such file or directory
so as I said earlier it tries to open: /usr/lib/arm-linux-gnueabihf/libGLESv2.so which apparently is not present or wrongly linked.

After that it tries your mali hack and succeeds, my opinion, rather than hacking the build system, make sure your links for /usr/lib/arm-linux-gnueabihf/libGLESv2.so are correct with that you don’t need to alter the code (or at least keep it to a minimum).
Also you can see your EGL fails completely, you have to hack that a little more and link it against mali as well.
EGL on X11 is disabled, which is what you want for desktop Qt5 applications, or else you can only run fullscreen (framebuffer) applications.

I’m trying another approach.
I’ve downloaded the Qtbase source code from official Ubuntu ppa and edited source code.

Code: Select all

apt source qtbase5-dev
cd qtbase-opensource-src-5.9.5+dfsg
vi src/platformsupport/eglconvenience/qxlibeglintegration.cpp

Then, I started to build with dpkg-build.

This time, the configuration looks much better. I didn’t change the soft-links of GL-ES libs.
The «rules» file in debian directory seems to be well made by Debian developers.

@meveric Thanks for pointing my mistake.
I fell their is an issue with symbolic link of the libGLESv2.so library in the /usr/lib/arm-linux-gnueabihf/

Code: Select all

odroid@odroid:/usr/lib/arm-linux-gnueabihf$ find /usr/lib -name libGLESv2.so
/usr/lib/arm-linux-gnueabihf/libGLESv2.so
/usr/lib/arm-linux-gnueabihf/mali-egl/libGLESv2.so
/usr/lib/chromium-browser/libGLESv2.so
odroid@odroid:/usr/lib/arm-linux-gnueabihf$ ls -la /usr/lib/arm-linux-gnueabihf/libGLESv2.so
lrwxrwxrwx 1 root root 18 Mar 5 09:45 /usr/lib/arm-linux-gnueabihf/libGLESv2.so -> libGLESv2.so.2.0.0

lrwxrwxrwx 1 root root 18 Mar 5 09:45 /usr/lib/arm-linux-gnueabihf/libGLESv2.so -> libGLESv2.so.2.0.0

To resolve this link issue I deleted the symbolic link and create proper link.

Code: Select all

odroid@odroid:~$ cd /usr/lib/arm-linux-gnueabihf
odroid@odroid:/usr/lib/arm-linux-gnueabihf$  sudo rm libGLESv2.so
odroid@odroid:/usr/lib/arm-linux-gnueabihf$  sudo ln -s libGLESv2.so mali-egl/libGLESv2.so.2.0.0

Now the linking is correct to library

Code: Select all

odroid@odroid:~$  ls -la /usr/lib/gcc/arm-linux-gnueabihf/7/../../../arm-linux-gnueabihf/libGLESv2.so
lrwxrwxrwx 1 root root 27 May 24 18:04 /usr/lib/gcc/arm-linux-gnueabihf/7/../../../arm-linux-gnueabihf/libGLESv2.so -> mali-egl/libGLESv2.so.2.0.0

Now coming to the issue of the configure failed for, it still fails at my end, dont know why.

Well that’s not exactly the correct way.
It’s ln -s <from> <to> you made a NEW link called mali-egl/libGLESv2.so.2.0.0 which points to libGLESv2.so what you actually want is the other way around.
Also for libGLESv2.so pointing to a libGLESv2.so.2.0.0 in the same folder is not wrong but actually fine, you have to check where libGLESv2.so.2.0.0 is pointing at.
And keep following it until you find the end-point and that needs to link against libmali.so.. something like this:

Code: Select all

ls -l /usr/lib/arm-linux-gnueabihf/libGLESv2*
lrwxrwxrwx 1 root root 14 Mär 14  2017 /usr/lib/arm-linux-gnueabihf/libGLESv2.so -> libGLESv2.so.2

same as libGLESv2.so the endpoint of libEGL.so should also point to libmali.so
HardKernel images had this issue numerous times in the past.
You need to make sure that libGLESv2 libEGL and libGLESv1_CM point agianst libmali.so.

Ok I found this qt5 wiki page related to odroid-xu3 https://wiki.qt.io/ODROID-XU3
and I updated the symbolic link as suggested by you and taking a note out of chromium-browser link symbolic.

Code: Select all

sudo ln -s /usr/lib/arm-linux-gnueabihf/mali-egl/libmali.so /usr/lib/arm-linux-gnueabihf/libEGL.so
sudo ln -s /usr/lib/arm-linux-gnueabihf/mali-egl/libmali.so /usr/lib/arm-linux-gnueabihf/libGLESv2.so

This changes seem to the trick for configure changes work at my end.

I could build the Qt 5.9.5 source in Canonical server finally.

Here is a quick and dirty build guide.

Install build-depends and source code.
sudo apt build-dep qt5-default
apt source qtbase5-dev
cd qtbase-opensource-src-5.9.5+dfsg

Edit a file for correct detecting the ARM’s Mali GPU.
Line 86 : src/platformsupport/eglconvenience/qxlibeglintegration.cpp
to : if (vendor && (strstr(vendor, "Vivante") || strstr(vendor, "ARM"))) {
from : if (vendor && strstr(vendor, "Vivante")) {

Another file should be edited to avoid a compile error. I wasted several hours to find this simple solution.
src/plugins/platforms/eglfs/deviceintegration/eglfs_kms_egldevice/qeglfskmsegldevice.cpp
http://code.qt.io/cgit/qt/qtbase.git/co … 9e6f24521e

Create two symlinks for proper OpenGL-ES detection. This fix will be included in the next update probably.
sudo rm /usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0
sudo rm /usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0
sudo ln -s /usr/lib/arm-linux-gnueabihf/mali-egl/libmali.so /usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0
sudo ln -s /usr/lib/arm-linux-gnueabihf/mali-egl/libmali.so /usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0

Build Qt5
sudo dpkg-buildpackage -b

I met this error when I ran it on a SSH session.
Project ERROR: QtDBus is enabled but session bus is not available. Please check the installation.
When I built it on the Mate desktop terminal instead of the remote ssh access, the build had no issue. It is still not understandable.

After 2~3 hours of boring build time, the «debian packaging» failed due to a missing PGP key.
But all the Qt5 libraries with examples were generated correctly and I could install them with sudo make install command.

Qt-OpenGL example works beautifully.

I hope I can learn how to make a «.deb» package for easier distribution soon.

check one folder above the build directory.
The building of .deb files does NOT fail due to missing PGP key, the only thing that will fail is the «signing» so the packages are build but not signed, but that’s not really an issue they will work fine nonetheless.

I’ve uploaded the pre-compiled Qt5 packages into our server.
Try the following steps to install it.

Code: Select all

sudo apt update && sudo apt upgrade
sudo apt install libfbclient2 libodbc1 libpq5 libsybdb5 libgles2-mesa-dev libxext-dev libinput-dev libxkbcommon-dev
wget https://dn.odroid.com/5422/ODROID-XU3/Ubuntu/qt5.9.5_armhf_bionic.tar.gz
tar xvfz qt5.9.5_armhf_bionic.tar.gz
cd qt5.9.5_armhf_bionic/
sudo dpkg -i *.deb

You can run an OpenGL ES 3.0 example powered by Qt5 if the installation has no issue.

Code: Select all

DISPLAY=:0.0 /usr/lib/arm-linux-gnueabihf/qt5/examples/opengl/hellogles3/hellogles3

If it works well, remove the downloaded packages to save disk space.

Code: Select all

cd ..
rm -rf qt5.9.5_armhf_bionic*

I think only a single packge is required… in fact it’s just a single .so file that’s why I made the fix package instead of uploading so many packages at once.
If you install libqt5gui5 on it’s own it should have the same effect. The rest can come directly from Ubuntu.

Ignore all the complicated installation guide.

Below steps should be enough now for Ubuntu 18.04 users since mdrjr uploaded the packages into the official ppa server.

Code: Select all

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

A new mali-x11 package was updated to fix the broken symlinks too.

@ageevp,

Can you run a Qt5 example?
Try this commands after the system upgrade.

Code: Select all

sudo apt-get install qtbase5-examples
/usr/lib/arm-linux-gnueabihf/qt5/examples/opengl/cube/cube

Anyway, the recent VLC does not work due to the transparent video rendering issue on the ARM platforms even you choose the video output option to OpenGL-ES2.

Try «ffplay»(a part of ffmpeg) with H.264 video files. It also works well with GPU/VPU drivers in Ubuntu 18.04.

I think VLC decoded data is not compatible with Qt video rendering input format.
I hope other Qt experts can give us deeper failure analysis.

It surprises me that todays image still has this issue, rather than the image having been fixed and re-uploaded in working condition. I will look for something else.

Download our package and install it manually as a temporary workaround.

Hi all

I was building 5.9 for GBM Mali driver, no X11 server running and it works fine, I had to change some source files to get it working !

@odroid

If you want the changes to provide a package that runs with X11 and without, let me know

Сборка Qt на Windows пошла найти, но у меня возникли некоторые проблемы при сборке на Linux Mint 18. Я скачал qt -where-opensource-src-5.7.0.tar.gz и распаковал его в / home / user / Qt- Статический / Qt5.7.0 /. Затем я запустил configure с помощью следующей команды:

./configure -platform linux-g++-32 -prefix /home/user/Qt-Static/Qt5.7.0 -static -opensource -confirm-license -opengl desktop -make libs

Изначально я получил ошибку:

фатальная ошибка: bits / c ++ config.h: нет такого файла или каталога

При поиске в Интернете я нашел решение этой проблемы — установить gcc-multilib и g ++ — multilib. После этого при запуске configure я получаю следующий вывод, который содержит ошибку «Проверка функциональности OpenGL не удалась!»

You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in
/home/user/Qt-Static/Qt5.7.0/qtbase/mkspecs/linux-g++-32.

После этого make-файл не генерируется. В поисках этой ошибки я нашел несколько вопросов с одной и той же проблемой и различные предлагаемые решения, но я не смог найти ничего, что сработало.

Я совершенно невежествен, когда дело доходит до Linux. Похоже, что я должен установить QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL а также QMAKE_LIBS_OPENGL, но я на самом деле не уверен, что их установить.

Может ли кто-нибудь помочь мне с этим?

Решение

Я обнаружил, что удаление -opengl desktop из моих параметров настройки решает проблему.

На окнах мне нужно было использовать -opengl desktop или я получил сообщения об ошибках OpenGL ES. Когда я запустил configure в Linux, я использовал ту же команду и просто изменил параметры -platform и -prefix, поэтому рабочий стол -opengl все еще был там. Я забыл, что это было там, но когда я заметил, я попытался удалить его, и это сработало, поэтому Qt сейчас компилируется. Спасибо за помощь.

Hello, I’m trying to update the system that I installed recently. But I’ve got an error:

Code:

ERROR: Feature ‘opengl-desktop’ was enabled, but the pre-condition ‘(config.win32 && !config.winrt && !features.opengles2 && (config.msvc || libs.opengl))

ERROR: Feature ‘egl’ was enabled, but the pre-condition ‘(features.opengl || features.openvg) && (features.angle || libs.egl) && (features.dlopen || !config.unix || config.integrity)’ failed.

ERROR: The OpenGL functionality tests failed!

You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],

QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

Earlier in the logs, did it say:

Code:

/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../lib64/libGL.so: undefined reference to `_glapi_tls_Current’

If so and you’re using nvidia, run:

Code:

emerge -1 nvidia-drivers xorg-server mesa

Then do your world update again.

Edit: Note that this isn’t a qtgui bug, it’s a widespread issue that can technically affect any package that depend on mesa during the libglvnd switch (portage gets the order wrong for nvidia-drivers rebuild). Exception is xorg-server since it added a blocker as a workaround. More likely to be an issue in large world updates. Thankfully, this is a 1-time deal, once rebuilt everything will be fine — just been a bit of a rocky transition.

Hi,

I got the same problem. This did not help:

Code:

emerge -1 nvidia-drivers xorg-server mesa

Hi there,

I would like to cross compile the welle.io software. It should work later on the Raspberry (OS: Raspbian).

Unfortunately I am unable to install qt5.

I follow instructions (https://github.com/AlbrechtL/welle.io/b … ERRY-PI.md)

The following must be carried out on the host system (desktop PC).

There are already problems in step 9 because «python» is not found:

Code: Select all

a@ubuntu:~/raspi$ ./sysroot-relativelinks.py sysroot
/usr/bin/env: ‘python’: No such file or directory

I then continued with the other steps anyway.

Well, qt5 cannot be configured either (step 12).

I use the following command:

Code: Select all

a@ubuntu:~/raspi/qt5$ ./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/raspi/gcc-linaro-5.5.0-2017.10-i686_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

(my host is a 64-bit system and not an ARM).

When I look roughly over it, I also find a few mistakes, e.g. at the end:

Code: Select all

ERROR: Feature 'opengles2' was enabled, but the pre-condition 'config.win32 || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed.
ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

I insert the complete edition here:
