Could you send me your Makefile snippet? I'd *love* to try that on my Octave
build process for the Debian package as we already have Atlas libraries.

I seem to have the static libs over two directories:

edd at sonny:/usr/lib> cd /; ls -l /usr/lib/{lib*atlas.a,atlas/*.a}
-rw-r--r--    1 root     root      3904916 Jan 19 10:27 /usr/lib/atlas/libblas.a
-rw-r--r--    1 root     root      6243568 Jan 19 10:27 /usr/lib/atlas/liblapack.a
-rw-r--r--    1 root     root      3572236 Jan 19 10:27 /usr/lib/libatlas.a
-rw-r--r--    1 root     root       153140 Jan 19 10:27 /usr/lib/liblapack_atlas.a

and there are of course shared libs as well:

edd at sonny:/> cd /; ls -l /usr/lib/{lib*atlas.so,atlas/*.so}
lrwxrwxrwx    1 root     root           12 Feb  5 09:54 /usr/lib/atlas/libblas.so -> libblas.so.2
lrwxrwxrwx    1 root     root           14 Feb  5 09:54 /usr/lib/atlas/liblapack.so -> liblapack.so.2
lrwxrwxrwx    1 root     root           13 Feb  5 09:54 /usr/lib/libatlas.so -> libatlas.so.2
lrwxrwxrwx    1 root     root           20 Feb  5 09:54 /usr/lib/liblapack_atlas.so -> liblapack_atlas.so.2


Cheers, Dirk
