Problem in FEniCS compilatin

Asked by Mohamed El-Amin

Dear Sir

I have installed FEinCS on my macbook which has Mac OS X version 10.6.8. I am trying to run an example of "stokes_example.py". I got the following error messages ,

elaminm@KL-11075:Nonlinear$ python stokes_example.py Calling FFC just-in-time (JIT) compiler, this may take some time.
In instant.recompile: The module did not compile, see '/Users/elaminm/.instant/error/instant_module_512026621ffb6cd40781116c7a38f228be2824b5/compile.log'

Googling your error message led me to this page:

  http://martinkou.blogspot.no/2011/05/how-to-solve-assembler-for-architecture.html

According to that page, you should be able to fix the problem by running the following two commands:

  sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/usr/libexec/gcc/darwin/ppc /Developer/usr/libexec/gcc/darwin
  sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/usr/libexec/gcc/darwin/ppc /usr/libexec/gcc/darwin
