Native compilation error on Fedora Rawhide (42)

[deamn]

Describe the bug
I try to compile native part on Fedora Rawhide and I have the following error. The same on Fedora 41 works well.

I see Fedora applied https://src.fedoraproject.org/rpms/eclipse-swt/c/132ea6893f6c05bdba23a223744aca210e7165f7?branch=rawhide to fix build of their rpm. I believe one would have to see the full log in order to figure out what the problem(and a fix for it) is.

I am reopening this one as it's very likely that the project will face the issue soon enough. If you can share full failing build log please do.
