Note: I started a thread in StackOverflow a few days ago with this question, but I have not received any response yet (the link is:
http://stackoverflow.com/questions/16093910/numpy-and-scipy-static-vs-dynami... )
The question is the following:
Say that I build ATLAS with LAPACK as follows:
wget http://sourceforge.net/projects/math-atlas/files/Stable/3.10.1/atlas3.10.1.t... wget http://www.netlib.org/lapack/lapack-3.4.2.tgz tar -jxvf atlas3.10.1.tar.bz2 mkdir BUILD cd BUILD ../ATLAS/configure -b 64 -Fa alg -fPIC \ --with-netlib-lapack-tarfile=../lapack-3.4.2.tgz \ --prefix=<ATLAS_INSTALL_PATH> make cd lib make shared make ptshared cd .. make install
Note that I did *not *pass the flag --shared in .my call to configure.
I end up with the following files under BUILD/lib:
Make.inc@ Makefile
the following .a files:
libatlas.a libcblas.a libf77blas.a libptf77blas.a libtstatlas.a liblapack.a libf77refblas.a libptlapack.a libptcblas.a
and the following .so files:
libsatlas.so* libtatlas.so*
Finally, if I define:
BLAS=/path_to_BUILD/lib/libcblas.a LAPACK=/path_to_BUILD/lib/liblapack.a ATLAS=/path_to_BUILD/lib/libatlas.a
and add /path_to_BUILD/lib to LD_LIBRARY_PATH and to the library_dirs variable within thesite.cfg file in NumPy.
Would NumPy and SciPy use my libraries? (even though they all seem to be static?).
Thanks,
Jason
