Hi, when I NMUed this package I've spent quite some time into a patch[1] to build with gcc-15. While I made some progress the problem is not yet fully solved. Given that upstream is not active any more I wonder whether it makes sense to remove this package from unstable/testing once Trixi is released. This would affect the cccc package (Colin in CC) which Build-Depends from pccts.
Kind regards Andreas. [1] https://salsa.debian.org/debian/pccts/-/blob/master/debian/patches/gcc-15.patch?ref_type=heads -- https://fam-tille.de
