This is most likely caused by not having the necessary graphics drivers installed. Install a driver providing OpenGL 2.0 or higher, or, if this is not possible, make sure the ANGLE Open GL ES 2.0 emulation libraries (libEGL.dll, libGLESv2.dll and d3dcompiler_*.dll) are available in the application executable's directory or in a location listed in PATH.

I’m in trouble
I render on a computing platform, where there is no graphical interface, and I have no permission to install software too.
I use the portable blender to render, and it can start rendering normally, but when the rendering is completed and the sampling is completed, it says «Finished», but then gives a lot of errors pop up. The rendered picture was not saved. The error is as follows:

EGL Error (0x3001): EGL_NOT_INITIALIZED: EGL is not initialized, or could not be initialized, for the specified EGL display connection.

libEGL warning: No hardware driver found, falling back to software rendering

EGL Error (0x3001): EGL_NOT_INITIALIZED: EGL is not initialized, or could not be initialized, for the specified EGL display connection.

Warning: No OpenGL vendor detected.

blender: ../external_epoxy/src/dispatch_common.c:872: epoxy_get_proc_address: Assertion `0 && "Couldn't find current GLX or EGL context.n"' failed.

I think the rendering has been completed, which shows that rendering is completely possible in this environment, but I really don’t know how to solve it, which is very important for me.

I don’t know if there is a solution. It is really useful to run on this computing platform.

What I do wrong?

I have application created with QT5 and Visual Studio 2013. I also use QT WebEngine in my application.

My application works fine in windows 7 (32 bit) . For some reason i need to run it in windows xp sp3 (32 bit).

When i run it, I get the following error:

The procedure entry point strnlen could not be located in the dynamic link library msvcrt.dll

I press OK several time and it goes away and my QMainWindow will pop out, But its totally BLACK and i see the following errors in debugger.

class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): Could not initialize EGL display: error 0x3001
class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): When using ANGLE, check if d3dcompiler_4x.dll is available

The d3dcompiler_47.dll is in application directory too.

Whats wrong here?

UPDATE 1

I placed 3dcompiler_46.dll in executable’s directory and this is what happened.

I still get The procedure entry point strnlen could not be located in the dynamic link library msvcrt.dll error but after i press Ok, I get the following error as well.

The procedure entry point _except_handler4_common could not be located in the dynamic link library msvcrt.dll

The QMainWindow is still BLACK and the errors about ANGLE is the same.

UPDATE 2

I build QT for Windows XP with following configuration

configure -release -opensource -opengl desktop -target xp -platform win32-msvc2013 -angle -icu -nomake examples -prefix C:QT-Compile

I replaced QT dependency and ran my application, I got the following errors:

The application has failed to start because icuin56.dll was not found
The application has failed to start because icuuc56.dll was not found

I tried to find them in QT directory (C:QT-Compile) and i couldn’t but i had them on main machine that run in Windows Seven, I placed them next to executable and application run successfully and previous errors are gone, However, The QMainWindow is still BLACK and i have the following errors in my debugger in run time.

QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
bool __thiscall QOpenGLTextureBlitter::create(void) Could not link shader program:

Whats wrong now ?

UPDATE 3

This is how i configured QT.

configure -release -opensource -opengl dynamic -target xp -platform win32-msvc2013 -icu -nomake examples -prefix C:QT-Compile

I used windeployqt.exe and placed required DLLs and … next to executable.

Ran application in windows xp and i keep getting following errors then application crash.

Hi, I’m trying to run a benchmarking tool on the Samsung Galaxy S5 to test some optimizations and perhaps start experimenting with the use of ASTC. It seems like the GL driver is failing to create a context without an associated window to render into. As you may know, opening a window on Android is a fairly involved process, so ideally I’d like to avoid it. I’ve attached the code that should be initializing the context and the results below:

EGLint error = EGL_SUCCESS;
if (EGL_SUCCESS != (error = eglGetError())) {
    Debugf("Prior EGL error: %sn", getEGLErrorStr(error));
    return NULL;            
}

fDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);
if (fDisplay == EGL_NO_DISPLAY || EGL_SUCCESS != (error = eglGetError())) {
    Debugf("eglGetDisplay failed -- error: %sn", getEGLErrorStr(error));
    return NULL;
}

EGLint majorVersion;
EGLint minorVersion;
if (EGL_TRUE != eglInitialize(fDisplay, &majorVersion, &minorVersion)) {
    if (EGL_SUCCESS != (error = eglGetError())) {
        Debugf("eglInitialize failed -- error: %sn", getEGLErrorStr(error));
        return NULL;            
    }
}

Debugf("Major: %d, minor: %dn", majorVersion, minorVersion);
Debugf("VENDOR: %sn", eglQueryString(fDisplay, EGL_VENDOR));
Debugf("APIS: %sn", eglQueryString(fDisplay, EGL_CLIENT_APIS));
Debugf("VERSION: %sn", eglQueryString(fDisplay, EGL_VERSION));
Debugf("EXTENSIONS %sn", eglQueryString(fDisplay, EGL_EXTENSIONS));

if (!eglBindAPI(EGL_OPENGL_ES_API)) {
    return NULL;
}

if (EGL_SUCCESS != (error = eglGetError())) {
    Debugf("eglBindAPI failed -- error: %sn", getEGLErrorStr(error));
    return NULL;            
}

EGLint numConfigs;
const EGLint configAttribs[] = {
    EGL_SURFACE_TYPE, EGL_PBUFFER_BIT,
    EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
    EGL_RED_SIZE, 8,
    EGL_GREEN_SIZE, 8,
    EGL_BLUE_SIZE, 8,
    EGL_ALPHA_SIZE, EGL_DONT_CARE,
    EGL_DEPTH_SIZE, EGL_DONT_CARE,
    EGL_STENCIL_SIZE, EGL_DONT_CARE,
    EGL_NONE
};

EGLConfig surfaceConfig;
if (!eglChooseConfig(fDisplay, configAttribs, &surfaceConfig, 1, &numConfigs)) {
    Debugf("eglChooseConfig failed. EGL Error: 0x%08xn", eglGetError());
    return NULL;
}

The output:

Major: 1, minor: 4

VENDOR: Android

APIS: OpenGL_ES

VERSION: 1.4 Android META-EGL

EXTENSIONS EGL_KHR_get_all_proc_addresses EGL_ANDROID_presentation_time

eglChooseConfig failed. EGL Error: 0x00003001

I’m hesitant to say that this is a bug in the driver, but I’m not totally sure what I’m doing wrong in my initialization code. Any help would be appreciated . Also, if this isn’t an appropriate forum for a question like this, I’d be glad to direct it to the right place.
