Hi Alan,
As promised: I have found that currently wxWidgets is not acknowledged by
PLplot on my laptop and I had a look at the report to find out why, because in
previous tests I did have it. Here is the situation:
- In december last year, the build did include wxWidgets, as witnessed
by a CMake output report from that date that I have on my computer. Currently,
however, it is refused because PLplot finds a version 2.8 of wxWidgets and not
3.0.
- My Cygwin installation has both 2.8 and 3.0 - the latter was updated
after said report (a matter of comparing the file dates).
- Why PLplot now does not find that 3.0 version is not clear to me. I
guess unstalling version 2.8 should work.
- I updated the setup utility for Cygwin a weeks ago, but that new version works differently
than the previous one. Searching for "wxWidgets" does not show which packages were
installed, but I just found out that searching for "wx" does. So I can uninstall 2.8 and
try again.
This 2.8 versus 3.0 issue is something we need to look into. For the moment I
will just continue with 3.0 only.
I don't really understand the module, but from the comments in
cmake/modules/FindwxWidgets.cmake, that module supports version
selection, and does the right thing if multiple versions are
available. So I have put into my post-release ToDo list that we
should drop our own brute-force version check (which doesn't work for
multiple versions like you had installed) and use the
FindwxWidgets.cmake version check instead.
But for now, you can work around the problem (as you have stated
above) by installing 3.0 only,
Alan
