Thanks for that fix. It turns out the above idea works. That is, if you insert (revision 10175) the stanza #if defined(plplot_pyqt4_EXPORTS) #define initplplot_pyqt4 PLDLLIMPEXP_PYQT4 initplplot_pyqt4 #endif in qt.h, then you get the following result: softw...@raven> nm --extern-only --defined-only ~/plplot_cvs/installcmake/lib/python2.5/site-packages/plplot_pyqt4.so 0000000000219ac0 A __bss_start 0000000000219ac0 A _edata 0000000000219b30 A _end 00000000000139c8 T _fini 0000000000005da8 T _init 00000000000064a1 T initplplot_pyqt4 and pyqt4_example.py works for both the downloaded Qt4 (with appropriately set LD_LIBRARY_PATH to force the system version of pyqt4 to point to the downloaded Qt4) and also the system version of Qt4. So subject to you possibly tweaking the crude hack above, I think we are finally done with qt visibility issues. Thanks for your essential help in getting this difficult problem sorted out. To our developers with access to Windows platforms: please test qt and especially pyqt4 access to PLplot now that the last qt visibility issue on Linux has been dealt with.
