[Getfem-users] Build getFEM++ on Mac OS 10.5

[James Zhou]

Hi,

I am having some trouble building getFEM++(version 4.1.1) on my macbook pro (version 10.5.8).  The compilers used are i686-apple-darwin9-gcc-4.0.1 and i686-apple-darwin9-g++-4.0.1.  Here are the steps I take:

./configure --with-blas=/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Versions/Current/libBLAS.dylib --disable-python

make

make check

The build is successful, but one of the tests failed:

Error in getfem_nonlinear_elasticity.cc, line 337 :

The full output of the test is:

Computing nonlinear elasticity accurately is important for my project. Any suggestions on how to fix this?  Thanks a lot!
