I am trying to compile a code for MATLAB. Actually is in C and there is an implementation in matlab. Thus I am using MinGW64 Compiler (C) compiler in order to compile the files. I am running the compiler script which actually compiles using the cmd all the c files. My problem is with a line with fflush(stdout); When I tried to run that command I am receiving the following message:
Undefined function or variable 'stdout'.
I am trying to figure out why am I receiving that error, and what is about.
The code is the following:
disp('Compiling for Matlab...');
gcc = 'mex';
cd mex;
% =============
% Learning code
disp('Learning:');
files = {'qp_one_sparse.cc', 'score.cc', 'lincomb.cc'};
matlabflags = '-O -largeArrayDims';
for n = 1:length(files)
cmd = [gcc ' ' matlabflags ' ' files{n}];
disp([' ' cmd]);
fflush(stdout);
eval(cmd);
end
I got issues with fflush(stdout); line

fflush(stdout) is valid in Octave but not MATLAB.
If you need to flush the output, you can drawnow to achieve the same effect in MATLAB.
drawnow('update')
The update parameter ensures that only non-graphical queues are flushed.
In newer versions of MATLAB, the following is preferred but either should work.
drawnow('limitrate')
That being said, I'm not sure that you even need it for the code that you've posted.
