Unable to compile wxPython 4.2.2 on Cygwin

[hamishmb]

Hi there,

I've been trying to compile wxPython 4.2.2 on Cygwin, but I keep running into an error where it's looking for setup.h under /usr/local/lib instead of just /lib. Then a bit later on it fails with fatal error: wx/wx.h: No such file or directory. The full output is below, along with the build command.

Build command:

LDFLAGS="-L/usr/lib -lpython3.9 -lX11 -lgtk-3 -lgdk-3" python3.9 ../build.py build_py --use_syswx --gtk3

Output:

I'm not quite sure where to start with fixing this, so any help is greatly appreciated.

The wx.h not found is most probably because the steps to generate the files from the repo's sources (to create a Python sdist) wasn't done or didn't complete successfully. If you don't need to highly customize the configure part, just ask for pip, uv, or build, to create a wheel from the sdist. You might have more luck skipping lots of steps.

The sdist is the same for Windows, macOS, and Linux.

Do you mean to say I need to use more commands than just build_py when running build.py? It works fine in wxPython 4.1 just running build_py, so I'd be surprised. I am using the system distribution of wxWidgets 3.2, note, rather than building wxWidgets along with wxPython - we like to keep those packages split apart.

I could try dropping the --use_syswx argument and see what happens though, might be interesting.

[hamishmb]

Update: dropping that argument made no difference at all.

Have you ever successfully built wxPython under Cygwin before? I'd be surprised if it worked. wxPython is not really set up for cross-compiling.

But specifically in this case, it seems strange to use the --use_syswx argument, as it is trying to use the Linux version of wxWidgets.

[hamishmb]

Yeah, I've built 4.0.x and 4.1.x successfully. Bear in mind this is building the GTK3 version, not the "native" Windows version - I'm not cross-compiling.

[swt2c]

Well for starters, your system wx needs to be v3.2.6.

Aside from that, you can set the WX_CONFIG environment variable to the path of your wx-config.

[hamishmb]

Yep, I've got wx v3.2.6.

Okay, thanks for the tip, I'll give that a go when I'm next working on this - I'm done for the day now.
