Error using mex for C++ on R2014a

Dear,

I have an issue with compiling a C++ package using MEX after I switched to MATLAB R2014a on my Windows 7 64-bit system. The problem is that I am not getting any information from the compiler regarding the specific error(s), even when using verbose mode.. this makes it rather impossible for me to even locate the problem.

The result from "mex -setup C++" is the following:

MEX configured to use 'Microsoft Windows SDK 7.1 (C++)' for C++ language compilation.

The mex command that is being executed is:

mex -v -O -I. -I'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab/bin/include' -I'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab/../../include' -I'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab/../../external_packages' -I'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab/../../external_packages/include' -I'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab/../../external_packages/qpOASES-3.0beta/include' -I'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab' -DWIN32 -D_cpluplus -D__MATLAB__ -Dsnprintf=_snprintf -Dround=acadoRound -O integrator/ACADOintegrators.cpp 'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab\bin/src/acado_io_utils.obj'

... (many, many object files) ...

'C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab\bin/src/acado_mat_file.obj' -outdir integrator/ -output ACADOintegrators.mexw64_

And the resulting output in the command window reads:

_... link /nologo /manifest /DLL /EXPORT:mexFunction C:\Users\Rien\AppData\Local\Temp\mex_62436292834793_3480\ACADOintegrators.obj C:\Users\Rien\Dropbox\ACADOstable\interfaces\matlab\bin\src\acado_io_utils.obj

Everything works perfectly with older versions of MATLAB on the same system, using the exact same compiler. Any hints on how to solve this problem or on how to receive more information from the compiler would be greatly appreciated!

Thank you and best regards,

Rien
