Ok, so I would like to incorporate some C code using mex, so I set about installing MinGW from TDM using the add-on provided by matlab. Every time I tried to install, I got an error saying I have the wrong version of mingw installed (which is ridiculous because I used the package downloaded from matlab, and yes, I unchecked the don't look for updates box). So I dug around in the script that checks the version I have installed. It's called mexSetupMinGW.m It runs fine up until line 136 when calling
[~, cmdout] = system([path_to_gcc , ' --version']);
cmdout is returned as an empty string, however when I type
C:\TDM-GCC-64\bin\gcc.exe --version
(the string sent to system() by [path_to_gcc , ' --version']) into command prompt I get this:
C:\>C:\TDM-GCC-64\bin\gcc.exe --version
gcc.exe (tdm64-1) 4.9.2

So the gcc.exe is there and it is the correct version, but something is going wrong on line 136 of mexSetupMinGW.m and I haven't the slightest idea of what to try next. Except maybe to manually set cmdout as the output I got from command prompt.
Anyone out there have any ideas?
edit:
Yep. I set cmdout = 'gcc.exe (tdm64-1) 4.9.2'; right under line 136 and the script executed properly. I then ran mex -setup and mingw64 popped up. That doesn't explain why system() was returning an empty string though...
