I'm running Ubuntu 12.04 64-bit with all the latest patches. For one of my projects, I'm using python-qwt3d-qt4. It wokked fine in 11.04, but it didn't in 11.10 (that's the reason I never installed 11.10 on my computer at work). Anyway, this package still isn't usable in 12.04. If I try to use it, I get this when starting my program:
ImportError: /usr/lib/pyshared/python2.7/PyQt4/Qwt3D/_Qwt3D.so: undefined symbol: gluCylinder
The error is the same I got a while back in Ubuntu Karmic (https://bugs.launchpad.net/ubuntu/+source/pyqwt3d/+bug/478230), and the solution is the same as it were then: -lGLU is missing when calling configure.py.
To fix this error, you need to change line 36 in debian/rules (pyqwt3d_0.1.7~cvs20090625-8.debian.tar.gz file) from:
python$$pyvers configure.py -$$qtvers -I /usr/include/qwtplot3d-qt$$qtvers --extra-libs=qwtplot3d-qt$$qtvers -l z -D GL2PS_HAVE_ZLIB);\
to (-lGLU added at the end of options):
python$$pyvers configure.py -$$qtvers -I /usr/include/qwtplot3d-qt$$qtvers --extra-libs=qwtplot3d-qt$$qtvers -l z -D GL2PS_HAVE_ZLIB -lGLU);\
I made a package for myself, so I can use this library, but please, change this line and make the package usable from main repository. I also included a patch for this. |
Impact:
python-qwt3d is unusable in precise as it can't be imported due to a undefined reference
Fix: link with GLU to satisfy the symbol
TEST CASE:
python -c "import PyQt4.Qwt3D"
expected: successful import
current:
ImportError: /usr/lib/pyshared/python2.7/PyQt4/Qwt3D/_Qwt3D.so: undefined symbol: gluCylinder
Regression potential:
just a link added, package broken before, very low chance of regressions
