Hi,

I am Debjit. I am trying to call Matlab Engine from C Program. I am using Matlab R2011a x86-64 bit version. I failed and I tried with the engdemo.c file included in the Matlab distribution. I tried to compile that with the following gcc command :

gcc engdemo.c -o engdemo.o -I$MATLABROOT/extern/include -L$MATLABROOT/bin/glnxa64 -leng -lmat -lmx -lut

But I got the error message as attached. Can you kindly suggest me what I am missing? I am using gcc version Red Hat 4.4.6-4. The following link contains the error message. http://web.engr.illinois.edu/~dpal2/MatlabError.txt. My final aim is to use the Statistical Toolbox of Matlab using Matlab Engine. looking eagerly for your suggestions.

Thanks and Regards,

Debjit.

If you check the verbose mode of mex -v you will see a lot of flags which you need. For the linking stage you need the -rpath and the libraries (-lmx -lmex etc.)

That should resolve the issue. Regards Friedrich

Is the shell variable MATLABROOT defined in your shell? If not then it is going to be replaced by the empty string. You would need to define it in the shell as the path that MATLAB is installed into. For example,

export MATLABROOT=/opt/software/matlab/matlabR2012b

but set as appropriate.
