[Numpy-discussion] Can Numpy use static libraries from LAPACK?

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-dynamic-loading
)
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.tar.bz2/download
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
