Hi Arjen:
Thanks very much for that quick turnaround.
You're welcome :)
I get compile errors as can be seen in the attached tarball (output
from CMake and make, as well as the config header file). We need to sort out
these
things before a comprehensive build is going to stand any chance.
From what I can tell from your current extremely limited make.out (please
generate
that next time with VERBOSE=1), it looks like these build issues have nothing
to do
with PLplot code and instead are wxwidgets header incompatibilities _for the
compile flags that are being generated by your current Unix wxwidgets find
method_.
Therefore, I am pretty sure the current build issue is caused by your build
using
Unix wxwidgets compile and link flags when it should be using Windows wxwidgets
compile and link flags for the MinGW-w64/MSYS2 platform. So to get access to the
latter flags, I suggest you use the _Windows_ wxwidgets find method (which I
understand you automatically obtain if you use the "MSYS Makefiles" generator.)
I do not think so, the condition definitely says "AND NOT MSYS" - so that would
use the Unix method.
You are right. So without your one-line change to
FindwxWidgets.cmake, the "Unix Makefiles" generator or "MinGW
Makefiles" generator will yield
set(wxWidgets_FIND_STYLE "win32")
while (confusing) the "MSYS Makefiles" generator will yield
set(wxWidgets_FIND_STYLE "unix")
If I have understood correctly what you said before, the Windows wxwidgets find
method currently does not work for the MinGW-w64/MSYS2 platform. Nevertheless,
since our wxwidgets code with old IPC method did build correctly on MSVC before
with this find method, I assume whatever correction you have to make to
cmake/modules/findwxWidgets.cmake to get the Windows find method to work
correctly on the MinGW-w64/MSYS2 platform should be quite small.
And as per usual, the cmake options --debug-output --trace are extremely useful
for
debugging find modules, but if those are not sufficient to discover the
problem, you
can always locally insert
message(...) commands in cmake/modules/findwxWidgets.cmake.
Ah, but the issue is that under MinGW-w64/MSYS2 things are installed
in different directories and possibly a different structure than under
Windows with MSVC. MinGW-w64/MSYS2 is a bit of a hybrid system, though
leaning towards the Unix way.
I agree on the hybrid nature of that platform and very likely part of
that is the wxwidgets libraries are built on MinGW-w64/MSYS2 the
"Windows" way since X is (thankfully since it is so slow on Windows)
not available on that platform.
Anyhow, I would advise dumping out compile (and link) flag results for both the
set(wxWidgets_FIND_STYLE "win32")
and
set(wxWidgets_FIND_STYLE "unix")
cases to see what the differences are (which I think were originally
designed for the "MinGW Makefiles" and "MSYS Makefiles" cases for the
old MinGW/MSYS platform).
Because of the hybrid nature of MinGW-w64/MSYS2 you might need some
combination of both sets of those compile flags (e.g., -I flags
from "unix" results and the other non-I compile flags from "win32"
results. Or vice versa).
