I'm trying to compile a matlab wrapper for libdc1394 which is a library for firewire cameras. I get a strange error involving some inline functions in a header file. I'm working on ubuntu 12.04 with gcc-4.6. I've compiled other mex files with success. This wrapper was also difficult to compile in mac.
/usr/local/MATLAB/R2012b//bin/mex dc1394mex.c `pkg-config --libs --cflags libdc1394-2` -o dc1394.mexa64
Warning: You are using gcc version "4.6.3-1ubuntu5)". The version

Any ideas?
Well Simons proposal was correct. Only catch I didn't know was that you can't give cflags directly to mex. You have to alter your mexopts.sh file. Also I had to remove -ansi flag because it contradicts with c99.
