[Plplot-devel] png driver no longer works for python

[Alan W. I. <ir...@be...>]

With plplot tree freshly updated from CVS, I configure like I normally do, e.g.,

./configure --prefix=/usr/local/plplot --with-double
--enable-dynamic-drivers --enable-java --enable-gnome > & ! configure.out

Then from tmp I executed
./pythondemos.py -dev png
Unable to load driver: gd.drv.
Reason: /usr/local/plplot/lib/drivers/gd.drv: undefined symbol: plP_setpxl
Segmentation fault

First, why should a test in tmp refer to some previously installed version
in /usr/local/plplot?
Second, when I removed /usr/local/plplot/* I got a new error message:

./pythondemos.py -dev png -o temp.png
Unable to load driver: gd.drv.
Reason: /usr/local/plplot/lib/drivers/gd.drv: cannot open shared object
file: No such file or directory

So somehow /usr/local/plplot is hardcoded in the python case.  With
/usr/local/plplot removed, I have no trouble with the png driver for the
x01c example, and the psc driver works both for the x01c and pythondemos.py
examples.

I am virtually positive I checked the png driver before when I was first
testing pythondemos.py.  Since then, I have changed to python-2.1 and Joao
has made some driver changes so I don't know which is causing the trouble.
Joao, can you replicate this problem on your (presumably) python-1.5 system?
