The first public release of PyXPlot
The first public release of PyXPlot has been announced. "PyXPlot is a
commandline graphing package, which, for ease of use, has an interface
based heavily upon that of gnuplot -- perhaps UNIX's most widely-used
plotting package.

I have been trying to build PyXplot tonight. First problem:
./configure quits because it can't find Python 2.4. OK, what I have
installed is 2.3.4. Go to the Python web site, find out that Python
2.5 was just released two days ago, download the source tarball and
build it.
Now pxyplot/.configure still quits because it can't find python 2.4.
True, it now finds 2.5. Hell of a note.
Suppose I could symlink /usr/local/bin/python to
/usr/local/bin/python2.4? That makes pyxplot/.configure work without
complaint. Make me wonder what would happen if I symlinked
/usr/bin/python2,3,4 to /usr/bin/python2.4. $PATH has
/usr/local/bin:/usr/bin:/bin as its search sequence.
OK, pxyplot needs scipy which needs numpy. Wonder what else is involved.
scipy also needs LAPACK, which is a gigantic software package. Quick check with
"yum list installed" shows that lapack is already present. Wonder
when I did that.
Building scipy seems to generate a 30MB library, full of stuff that
probably isn't needed for just making pretty graphs.
Really time to quit for the night.
Once more into the fray. Now pxyplot seems to build, but when the
Makefile tries to build the example plots to go into the
documentation, it bombs out with an error in a library that was built
for scipy:
- - - - -
ImportError: /usr/local/lib/python2.5/site-packages/scipy/linalg/fblas.so:
undefined symbol: srotmg_
- - - - -
This is much too deep for me right now. fblas is something like basic
linear algebra subroutines. Why at this date (perhaps 30 yrs after it
was first written) should there be undefined symbols cropping up?
