Trying to build aMule 2.3.3 on my Gentoo musl box it errors out with MuleDebug.cpp:70:14: error: 'set_terminate' is not a member of 'std'

Same with git HEAD. But it builds fine on my other Gentoo box with glibc C-Library.

Here is the Gentoo downstream bug report: https://bugs.gentoo.org/872263

This will happen for GCC 11 or later. Try this patch: https://github.com/minnyres/amule-win32/blob/main/patches/amule-fix-exception.patch

Thanks! With this patch 2.3.3 and HEAD build fine.

If it's a general GCC>=11 problem I guess the patch will be merged in git-master?

Yes I think it will be merged in git-master one day, but this project is not under active development recently since the maintainers have their own life.
