Fails to build with python bindings / Shiboken missing definitions for fixed width integer types

[FalcoGer]

Environment information

• Operating System: Ubuntu 24.04 (Ubuntu 24.04.2 LTS)
• Cutter version: Github Stable Branch (commit a5f88d1 (HEAD -> stable, tag: v2.4.1-rc1, tag: v2.4.1, origin/stable))
• Obtained from:
  • Built from source
  • Downloaded release from Cutter website or GitHub
  • Distribution repository
• File format: ?

Describe the bug

ninja from the build directory from cutter after cmake and enabling python bindings results in a compilation error, both when using clang/clang++ or gcc/g++.

To Reproduce

Steps to reproduce the behavior:

1. Git clone cutter with submodules
2. Switch to stable branch
3. Update submodules
4. Create build directory
5. cmake-gui, switch on python bindings (I also turn on all the plugins and packaging), switch to QT5.
6. build with ninja

Expected behavior

Compiles, because all dependencies are installed.

Screenshots

N/A

Additional context

I think it might be a missmatch between shiboken being linked against llvm's c++ standard library and cutter being linked against gcc's standard library? Not sure.
System python version is 3.12 from ubuntu apt repositories.

Ubuntu 24.04 is one of the first ubuntu versions that finally provides shiboken6 why are you forcing QT5?

because i upgraded from 22.04. and I don't want to track down another 42 QT packages because there isn't just a install once and done thing.

also can't find this shiboken6 package.

Sorry must have misremembered it. Seems like it's 24.10 and 25.04 not 24.04. Ubuntu with their animal names sometimes make their versions unclear.
