[Plplot-devel] Commit e4fb932 introduced a wxPLViewer build bug on Linux (wxWidgets 3.0.2)

[Alan W. I. <ir...@be...>]

Hi Phil:

The wxwidgets-related parts of my cmake output are

software@raven> grep -i wx cmake.out
-- Found wxWidgets: -L/usr/lib/x86_64-linux-gnu;-pthread;;;-lwx_baseu-3.0;-lwx_gtk2u_core-3.0 (found suitable version "3.0.2", minimum required is "3.0.0")

ENABLE_wxwidgets:       ON

Note especially my wxWidgets library version (3.0.2) because I think
that may be relevant to this build bug.

The compressed version of wxPLViewer.out that shows the build bug is attached
where that file was created with

make VERBOSE=1 wxPLViewer >& wxPLViewer.out

Those results were for commit 476ce73 (current master HEAD) on
Linux.  I just did a git bisect, and the first commit that introduced
this issue was actually

e4fb932... Set the option of a render delay after resizes on wxPLplotwindows.

The above results were for the -DPL_WXWIDGETS_IPC3=OFF case,
but there are similar (and possibly the same) issues for the
-DPL_WXWIDGETS_IPC3=ON (default) case so whatever the problem
is, it is likely common to both the IPC3 and non-IPC3 cases.

Since presumably you did a successful build test yourself for commit
e4fb932 or after, my best guess is this issue has to do with our
differing wxWidgets library versions (3.0.2 for me and 3.1.0 for you).
Since I believe you throughly understand the differences between 3.0
and 3.1, I hope the issue is due to that difference and will therefore
be easier for you to fix.
