Errors running faster_rcnn_build.m

[klroth]

When I run the file, I get the following error:

faster_rcnn_build Compiling nms_mex Building with 'MinGW64 Compiler (C++)'. Error using mex g++: error: -fexceptions: No such file or directory

Error in faster_rcnn_build (line 13) mex -O -outdir bin ...

If I run with the -v option enabled, here is the output:

faster_rcnn_build Compiling nms_mex Building with 'MinGW64 Compiler (C++)'. Error using mex g++: error: -fexceptions: No such file or directory Using built-in specs.

I have made sure that all the folders and subfolders are properly added to the path. I am running MATLAB 2016a on a Windows 7 64 bit OS. I've set up the MinGW64 compiler for C++:

MEX configured to use 'MinGW64 Compiler (C++)' for C++ language compilation.

Any help would be greatly appreciated! I am stuck at this point...

After checking each dir listed in the output above, I found the following non-existent:

C:\Program Files\MATLAB\R2016a\extern\include\win64

The rest seem to exist. Not sure why this one doesn't, or if this is even the cause of the issue. Any help would be greatly appreciated!

Hello I think you need to remove the \ from

 mex -O -v -outdir bin ...
      CXXFLAGS="\$CXXFLAGS -std=c++11"  ...
      -largeArrayDims ...
      functions/nms/nms_mex.cpp ...
      -output nms_mex;

to be

mex -O -v -outdir bin ...
      CXXFLAGS="$CXXFLAGS -std=c++11"  ...
      -largeArrayDims ...
      functions/nms/nms_mex.cpp ...
      -output nms_mex;

@klroth Are you already solved it?
