The change that broke this was around 5.23.6: https://perl5.git.perl.org/perl.git/commit/7a4fcb3f64df51eacf89f69a4bf76386aea1e8e3 It looks like we are relying on a Configure feature that is now considered a bug. We write some cross compiling information into optdef.sh in the main build directory but that no longer gets read. When I implemented this, I interpreted the override flag (-O) to mean that a separate optdef.sh needs to be supplied manually. However, the flag was since turned on by default in https://perl5.git.perl.org/perl.git/commit/41d73075f0801c26794dadb1ff690f305d7e53a7 and it seems the semantics changed a bit there. It's all something of a mess. Not sure how to best fix it yet. The file that now gets read in, UU/optdef.sh, is deleted at the start of Configure afaics. -- Niko Tyni nt...@debian.org
