Linking MKL libraries in MacOSX 10.7.2 (Lion)

Hallo all,

I'm linking the MKL libraries using the loading option

-L /Developer/opt/intel/composer_xe_2011_sp1.6.038/mkl/lib -lmkl_lapack95_lp64 -lmkl_intel_lp64 -lmkl_solver_lp64 -lmkl_core -lmkl_intel_thread

but I get the following error message while running the program:

dyld: Library not loaded: libmkl_intel_lp64.dylib

Referenced from: /Users/Work/my_dir/program_folder/main/./program_name

Reason: image not found

Trace/BPT trap: 5

I thought the problem was the setting of the environment variables. I did this by running the scriptmklvars_intel64.sh, but nothing changed. I also tried editing the .bash_profile and adding the lines

source /Developer/opt/intel/composer_xe_2011_sp1.6.038/mkl/bin/intel64/mklvars_intel64.sh

export DYLD_LIBRARY_PATH='/Developer/opt/intel/composer_xe_2011_sp1.6.038/mkl/lib'

but this also didn't work. Anybody can please help?

Thanks a lot in advance.

I found out that if I type

source /Developer/opt/intel/composer_xe_2011_sp1.6.038/mkl/bin/mklvars.sh intel64

in the command line, the program starts working!

But I don't like to have to type this anytime I open a new terminal window...I thought having this line in the .bash_profile would suffice, instead it does not.

Anybody can help?

Short answer: move it from .bash_profile to .bashrc !

In the original design of Unix shells, putting this kind of command in .bash_profile should have sufficed, but there are now so many ways to start shells that bypass the effects of .bash_profile (or its equivalent for other shell programs) that it is more practical to put things in the more ubiquitous .bashrc (or its equivalent for other shell programs).

Thanks Kurt, but actually I had already tried that, and it doesn't work...is there a way I can find out which file is used as profile for my shell?

Thanks

Hello!

Try putting it in your ~/.profile(it works for me).

Cheers!
