Hi Hazen:
Could you please test commit 578b028? For that commit I made some
modest progress with Python 3 for both pyqt4 and pyqt5, but I have hit
a roadblock with a run-time error saying the plplot_pyqt[45] extension
modules are not initialized properly when the script tries to import
one of those modules. The sip, pyqt[45], and python3 software
packages are all supposed to work well together for their latest
versions according to my google search results, but it is possible the
Debian Jessie versions of these software packages are too old and
buggy which is why I am asking you to test this commit by attempting
to build the test_pyqt[45]_example target (depending on whether your
build system finds Qt4 or Qt5) for both the python2 and python3 cases
(where the former builds and runs plplot_pyqt[45] without issues here,
but the latter case only builds these extension modules without
obvious issues but runs into initialization errors at run time).
The test_pyqt4_example target build all
prerequisites with success but fails the final run-time test.
Here is the relevant error message if I attempt to do the
run-time test by hand:
software@raven> python3 examples/python/pyqt4_example.py
Traceback (most recent call last):
File "examples/python/pyqt4_example.py", line 33, in <module>
import plplot_pyqt4
ImportError: dynamic module does not define init function (PyInit_plplot_pyqt4)
Do you get a similar error there or success?
For the record here is the complete list of python3-related packages
I have installed on Debian Jessie. If you think I am missing anything
please let me know.
