Build shared libraries in ATLAS

Question

I've read the entire ATLAS installation guide, and it says all you need to build shared (.so) libraries is to pass the --shared flag to the configure script. However, when I build, the only .so files that appear in my lib folder are libsatlas.so and libtatlas.so, though the guide says that there should be six others:

libatlas.so, libcblas.so, libf77blas.so, liblapack.so, libptcblas.so, libptf77blas.so

After installation some of the tests fail because these libraries are missing. Furthermore, FFPACK wants these libraries during installation.

Has anyone encountered this? What am I doing incorrectly?

In my experience, it's a lot more complex than that, see our EasyBuild implementation of the ATLAS build procedure at https://github.com/hpcugent/easybuild-easyblocks/blob/master/easybuild/easyblocks/a/atlas.py .

We needed to:

• enable the -fPIC compiler option
• run 'make shared cshared ptshared cptshared' in the 'lib' directory

We're not even using --shared for configure, probably because it doesn't do much.

If you want to build ATLAS (and whatever you will be linking it with) without headaches, look into EasyBuild.
