[SOLVED] «unknown type name ‘FILE'» inside of GNU Readline
I just switched to Arch today and am trying to make sure I have everything configured fairly well.
One thing I’m trying to do is ensure that I can compile my old projects, but I’ve run into the issue in this ( https://github.com/bwbuhse/ee461s_project_1 ) project that readline doesn’t include <stdio.h>
Any ideas on what I’m doing wrong? This compiled fine on my old Mint installation.

https://pastebin.com/eL3KxSB9 here’s a link to a pastebin of the full output when I try to compile

Re: [SOLVED] «unknown type name ‘FILE'» inside of GNU Readline
To compile with readline, you’ll need additional flags. Use pkgconf for determining the required compilation flags, i.e.:
pkgconf --cflags readline—edit: Same for the linking step. `-lreadline` is correct, but I wouldn’t hardcode it, but also use the output of `pkgconf —libs` there.

Re: [SOLVED] «unknown type name ‘FILE'» inside of GNU Readline
Ayekat, that doesn’t help. The OP’s concern is that readline itself uses FILE but does not include the header in which it is defined. This does seem wrong to me — though readline’s man page shows that one must include stdio.h themselves to use readline: so it is documented.
But bwbuhse, you also use printf in your code, so you definitely need to include stdio.h. I can only assume that what ever distro/compiler you previously used just included common things for you.

Re: [SOLVED] «unknown type name ‘FILE'» inside of GNU Readline
Would you look at that, Trilby, you’re right. I’d tried including it before but I guess I needed to include it above where I included readline. Thanks!

Re: [SOLVED] «unknown type name ‘FILE'» inside of GNU Readline
Ah yes, I should’ve tested it myself, sorry for the noise.
I had assumed that the additional `-D_…` parameters would cause the readline header to include the right headers (or rather define the right macros) to eventually get all the required definitions, but… nope.
It’s indeed weird that including the required header files is left to the programmer… but I guess if it’s documented, one cannot really complain too much :-/

Hello Community, I have a RPI that is reading sensorvalues from another board by I2C. Now I want to send the data to the scope. I searched around the forum, and found an entry where somebody wanted to achieve the same. He used the following code:
function y = fcn()
persistent pf;
pf = coder.opaque(‘FILE *’);
y = coder.nullcopy(uint8(0));
res = coder.nullcopy(uint8(zeros(1, 10)));
readOnly = c_string(‘r’);
readCmd = c_string([‘i2cget -y 0 0x06 49’]);
if isequal(coder.target, ‘rtw’)
pf = coder.ceval(‘popen’, coder.rref(readCmd), coder.rref(readOnly));
coder.ceval(‘fgets’, coder.wref(res), 10, pf);
coder.ceval(‘printf’, c_string(‘%s’), c_string(res));
end
end
function str = c_string(str)
str = [str, 0];
end
I get the following error, when using it:
The call to realtime_make_rtw_hook, during the after_make hook generated the following error:

I am using the studentversion of Matlab R2013a, could this be the problem?
Thanks for helping! Max

Nice to see someone using the RaspberryPi like this.
Two issues: you need to include stdio.h (for the definition of popen and the type FILE) and you’ll likely run into the problem described in:
You can add:
coder.cinclude(‘<stdio.h>’);
to your source code to include stdio.h.
Not defining _XOPEN_SOURCE or related as that post describes causes the C compiler to assume that popen returns an integer which you are then assigning to a FILE *, so it complains.
To follow the suggestion of defining _XOPEN_SOURCE to 500 you could update the build settings in «Simulation -> Model configuration parameters -> Code generation». Copy the TMF file you are using somewhere you can edit it:
copyfile([matlabroot ‘/rtw/c/grt/grt_unix.tmf’],‘./grt_posix.tmf’)
if you were using the grt default TMF file. In this file add a preprocessor define
(or whatever you need) to a line like:
CPP_REQ_DEFINES = -DMODEL=$(MODEL) -DRT -DNUMST=$(NUMST)
-DTID01EQ=$(TID01EQ) -DNCSTATES=$(NCSTATES) -DUNIX …
Finally enter the path to your new file in the «Template makefile» box in configuration parameters.
Also, are you passing a uint8 array to FGETS intentionally? You may consider allocating a character array instead:
res = coder.nullcopy(blanks(10));
as passing an unsigned array may cause the compiler to complain again.
Lastly, you may want to consider passing an appropriate integer type for the second argument of FGETS as it expects an int:
In MATLAB writing 10 means a double with the value of 10 (similar to 10.0 in C). So passing something like int32(10) (or whatever matches int on the Pi) could be preferable.
