Build on OpenBSD 7.0 fails - undefined cxx_throw test_eh_personality #216

Closed rmottola closed 9 months ago

A fresh build, fresh configured with "ccmake ." yields:

[ 12%] Linking C executable CXXExceptions_legacy_optimised
ld: error: /home/multix/code/gnustep-svc/libobjc2/Build/libobjc.so: undefined reference to cxx_throw() [--no-allow-shlib-undefined]

This still happens on 7.2, something gets detected wrong. If I turn off OLDABI_COMPAT I get the same error, in a different file

The CMake has now been reworked and has a bunch of bug fixes. Can you try again?
