Build Failure on Manjaro Linux 24/Fedora 40 and wxPython==4.2.1

[wieluk]

Building wxPython 4.2.1 fails due to an incompatible pointer type error in siplib.c, specifically:

../../../../sip/siplib/siplib.c:3900:20: error: assignment to ‘sipSimpleWrapper *’ from incompatible pointer type ‘PyObject *’ [-Wincompatible-pointer-types]

This occurs across multiple OS/Python versions.

Affected Configurations

OS	Python Version	wxPython Version	Status
Manjaro Linux 24	3.8	4.2.1	❌ Build Fails
Manjaro Linux 24	3.9	4.2.1	❌ Build Fails
Manjaro Linux 24	3.10	4.1.1	❌ Build Fails
Manjaro Linux 24	3.10	4.2.1	❌ Build Fails

Suggested Workaround

Use wxPython 4.2.2, as previous versions fail to build.
