I've (finally) found some time to do some work on plplot again. I've noticed for a while that the python bindings were failing ctest on my debian and ubuntu systems, but since I don't use python I'd not looked further.
Turns out that the problem is with multiple versions of python on the same machine. My default python /usr/bin/python is a symlink to python2.4, however FindPythonInterp looks for specific versions (python2.5 python2.4 ... ) before looking for python. This means that it picks up python2.5 as the interpreter. Similarly for the locations of the python libraries. When I come to run ctest the scripts call /usr/bin/python as the interpreter, but this is the wrong version and I get a seg fault. Has anyone else run into this problem? I can see 3 alternative routes to solve this. 1) Set all the python related cmake variables by hand (a little tedious). 2) Alter the python scripts so you can substitute in the name of the interpreter that was actually used to build plplot. 3) Alter the cmake modules so you can specify a prefered python version which will then propagate through when it comes to looking for the interpreter and the libraries. Only 2) would fix ctest out of the box which is generally a "good thing" for new users. Why am I suddenly interested in python? Well, I've been trying to port the debian packages to the new CBS so we can continue to support Debian and Ubuntu. This includes the python-plplot package. This actually involves building the bindings for multiple versions of python, which could potentially be a little tricky with the cmake system as-is. Option 3) would probably help. More on the debian packages later though.
