[SciPy-user] Ubuntu Libraries
Mon Oct 6 12:47:06 CDT 2008
I was hoping someone could clarify the ubuntu packages and what is actually
needed by scipy.
1) I keep seeing posts about g77 not being required anymore and gfortran
preferred. What is the "official" statement? In INSTALL.txt, only g77 is
mentioned for Ubuntu packages via: """Debian/Ubuntu packages (g77):
atlas3-base atlas3-base-dev""". The only reference to gfortran is with Mac
OS X. Also, in "Optional Packages" debian packages 'gcc g++ g77' are
2) The install notes also say that a complete version of LAPACK is required
for scipy. All the ubuntu descriptions say that only a subset of routines
from LAPACK are included with ATLAS. For example,
http://packages.ubuntu.com/hardy/libatlas-sse2-dev. Is this a problem?
3) It looks like there are two packages: atlas3-sse2 and
libatlas-sse2-dev. Are both required? It seems that they refer to
different versions of ATLAS.
On reading http://www.scipy.org/Installing_SciPy/Linux, it seems like I only
should need libatlas-sse2-dev. Correct?
