Bug 1957142

Created attachment 1779698 [details]
wxWidgets minimal example program

Description of problem:
-----------------------
After in-place upgrade from F33 to F34 I end up with wxGTK3 libraries in `/usr/lib64/libwx*` compiled with a different C++ ABI - perhaps g++ 10?) than the g++ stock compiler. Compiling a wxWidgets GUI app on this system with stock g++ 11(1.1) and linking it to the installed wxGTK3 libraries succeeds, but creates a run-time warning like this:

10:44:24: Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1015,wx containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1016,wx containers,compatible with 2.8).

How reproducible:
-----------------
Compile any wxWidgets program using F34 default g++ compiler (version 11.1.1) and link against the system's wxGTK3 libraries. On execution you get above ABI incompatibility warning.

Steps to Reproduce:
1. compile attached minimal.cpp wxWidget sample application:
# make -f makefile.unx
This should compile and link without any problems/warnings.

2. run it:

# ./minimal
11:04:33: Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1015,wx containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1016,wx containers,compatible with 2.8).


Actual results:
---------------
A warning printed to the console at run-time when executing a self-compiled wxWidgets (GTK3) application.
The installed wxGTK3 libraries are compiled with an outdated C++ ABI:

# for f in `ls /usr/lib64/libwx*`; do strings $f | grep 'ABI '; done
3.0 (wchar_t,compiler with C++ ABI 1015,wx containers,compatible with 2.8)
3.0 (wchar_t,compiler with C++ ABI 1015,wx containers,compatible with 2.8)
3.0 (wchar_t,compiler with C++ ABI 1015,wx containers,compatible with 2.8)
...


Expected results:
-----------------
No warning at run-time of self-compiled wxWidgets (GTK3) application.
The wxGTK3 libraries should be ABI compatible with the stock g++ compiler:

# for f in `ls /usr/lib64/libwx*`; do strings $f | grep 'ABI '; done
3.0 (wchar_t,compiler with C++ ABI 1016,wx containers,compatible with 2.8)
3.0 (wchar_t,compiler with C++ ABI 1016,wx containers,compatible with 2.8)
3.0 (wchar_t,compiler with C++ ABI 1016,wx containers,compatible with 2.8)
...
# touch foo.h; cpp -dM foo.h  | grep __GXX_ABI_VERSION
#define __GXX_ABI_VERSION 1016
