problem with ssc_build to generate custom simscape library

Hi everyone, I am trying to learn how to make custom simscape blocks. All I have done is to copy some of the existing ssc files from the simscape library into a new directory (named +MySimscape_lib) that I added to my Matlab path. Then, I run the ssc_build command to generate my custom library. When run the ssc_build command I get the following error message:

Generating Simulink library 'MySimscape_lib' in the MATLAB package parent directory '/users/Gabri KTH/Desktop/GB_Documents/Matlab_myadds' ... /Applications/MATLAB_R2012a.app/bin/mex: line 1022: [: /Users/Gabri: binary operator expected

Error: Could not create TEMP = /users/Gabri KTH/Desktop/GB_Documents/Matlab_myadds/+MySimscape/sscprj

Failed to generate 'MySimscape_lib'

Caused by: Error using mex (line 206) Unable to complete successfully.

Any idea what the problem can be? I have also a problem when I try to modify the source code of the Simscape original blocks. When I run the Simscape simulation that includes the modified block the simulation does not compile and I get this message on the command line:

/Applications/MATLAB_R2012a.app/bin/mex: line 1022: [: /Users/Gabri: binary operator expected /Applications/MATLAB_R2012a.app/bin/mex: line 305: gcc-4.2: command not found /Applications/MATLAB_R2012a.app/bin/mex: line 1326: gcc-4.2: command not found

    mex: compile of ' "/private/tmp/tpcf642ac4_9945_468c_9638_a4fe0d665d44.c"' failed.
Are the two problems connected?
Thanks for your help!

Hi, Have you a compiler installed on your computer? Try to run the command "mex -setup", it could be the problem if you use a 64-bit version
