Hi, I have a question with compiling the toolbox. I hit this error when I run vl_wsddn_compilenn in MATLAB(I also couldn't find cnn_wsddn_compilenn).

warning "SSSE3 instruction set not enabled. Using slower image conversion routines."

^ Warning: No source files in argument list. Assuming C source code for linking purposes. To override this assumption use '-fortran' or '-cxx'. /usr/bin/ld: cannot find -lstdc++ collect2: error: ld returned 1 exit status mex: link of ' "/home/hanwang/WSDDN/matconvnet/matlab/mex/vl_nnconv.mexa64"' failed. Unable to complete successfully. Error in vl_wsddn_compilenn>mex_link (line 506) mex(mopts{:}) ; Error in vl_wsddn_c ompilenn (line 458) mex_link(opts, objs, mex_dir, flags.link) ;

Any idea how do i fix this? Thanks.

Sorry I have just seen this. I believe this should be a matconvnet problem. Please have a look at https://groups.google.com/forum/#!forum/matconvnet
