Interfacing LevMar with mex

Hello there,

I am currently trying to interface the LevMar algorithm but I am getting errors during mex-compilation. The ultimate goal would be to use the LevMar-Algorithm to generate code via simulink embedded coder.

To build the LevMar library with MSVC2010 i followed this guide. During MSVC compilation and also for the mex-command I used the x64 precompiled LAPACK/BLAS/F2C libraries from here.

I then put the whole output (.lib and .obj from MSVC) and all downloaded libs into one folder (C:\code\libs) and run the following command on the already provided levmar.c:

mex -DHAVE_LAPACK -I.. -O -LC:\code\libs levmar.c -llevmar -lclapack -lBLAS -llibf2c -lBLAS_nowrap

which results in the following list of errors:

Error in MexCommand (line 21)
mex -DHAVE_LAPACK -I.. -O -LC:\code\libs levmar.c -llevmar -lclapack -lBLAS -llibf2c -lBLAS_nowrap

>> MexCommand

Does anyone have an idea what could be the mistake, or what might be missing?

Many thanks and best regards, Alain
