Why am I unable to compile a C shared library on a MAC Snow Leopard with MATLAB Compiler 7.11 (R2009b) ?

I am trying to compile a C shared library from MATLAB 7.9 (R2009b) and I get the following errors:

 

/Applications/MATLAB_R2009b.app/bin/mbuild: line 1749: gcc-4.0: command not found

mbuild: compile of ' "/Users/panagas/work/yo_wrapper/lab_lib/src/imuLabLib/src/libImuCalibration.c"' failed.

Error: An error occurred while shelling out to mbuild (error code = 1).

I was able to compile this same code earlier with Leopard. I recently upgraded to Snow Leopard.

When upgrading from Leopard to Snow Leopard, XCode does not get upgraded by default. In order to be able to compile your code with the MATLAB Compiler 7.11 (R2009b), you should do either one of two things:

1) Upgrade your XCode to Snow Leopard.

2) Create a symbolic link from /usr/bin to the actual location where GCC is installed. The name of the symbolic link should be gcc-4.0. The command to create this link will be

 

ln -s MYTARGET gcc-4.0

where MYTARGET is the location where the GCC compiler is installed on your system.
