Hi,
I have matplotlib installed and it runs properly. However, I also want
to use pysqlite, and it seems that the only way to use pysqlite on my
system is to first set LD_LIBRARY_PATH to /usr/loca/lib. But if I do
this, then I am no longer able to make matplotlib work. Here is the
traceback:
$ export LD_LIBRARY_PATH=/usr/local/lib
$ python
Python 2.4.3 (#2, Oct 6 2006, 07:52:30)

>>> import pylab

ImportError: /usr/lib/libgdk-x11-2.0.so.0: undefined symbol:
cairo_xlib_surface_create_for_bitmap
Why is the system having trouble finding the cairo library. Shouldn't
it just look in /usr/local/lib first (as specified by LD_LIBRARY_PATH)
and then move onto the other directories it looks for where it finds
all the files it was finding when LD_LIBRARY_PATH was unset? Does this
mean that I maybe have some other versions of pylab's dependencies
installed in /usr/local/lib which get loaded up first and cause the
problem? If so, then how can I check that is the case, and how can I
remove them.
Any help would be greatly apprecaited.
Thanks,
Ali.
