Comment(by drkirkby):
It's not so easy to test the upstream source code directly, as there are
dependencies which are not provided on Solaris. On 't2.math' I get:
{{{
kir...@t2:32 ~/matplotlib-1.0.0$ python setup.py build
basedirlist is: ['/usr/local']
============================================================================
BUILDING MATPLOTLIB
matplotlib: 1.0.0
python: 2.4.4 (#1, Jan 10 2007, 01:25:01) [C]
platform: sunos5
REQUIRED DEPENDENCIES
numpy: no
* You must install numpy 1.1 or later to build
* matplotlib.
}}}
But Numpy has a whole list of dependencies of its own, so I don't want to
spend a long time setting that lot up.
But I just retried your .spkg on 't2' using a working copy of the latest
{{{sage-4.5.3.alpha0}}} and find exactly the same problem.
I also tried on my !OpenSolaris machine inside a slightly modified version
of {{{sage-4.5.3.alpha0}}}. Again, I get the same problem as before.
To me this looks like an upstream bug, and not anything introduced in
Sage.
I just checked the source code, and see the code is actually in
matplotlib-1.0.0.
{{{
// Prevent multiple conflicting definitions of swab from stdlib.h and
unistd.h
#if defined(__sun) || defined(sun)
#if defined(_XPG4)
#undef _XPG4
#endif
#if defined(_XPG3)
#undef _XPG3
#endif
#endif
}}}
It seems a bit of a hack to me. If {{{_XPG4}}} or {{{_XPG3}}} are defined,
there were defined for good reason, and I doubt simply undefining them is
the right way to tackle this. I could imagine this could cause a whole lot
more problems than it solves.
According to http://en.wikipedia.org/wiki/X/Open the
[http://en.wikipedia.org/wiki/Single_UNIX_Specification Single UNIX
Specification] was based on the XPG4 standard, so I would not be surprised
that undefining {{{_XPG4}}} will cause problems as the behavior of
hundreds of header files will be changed.
