Hi Kurt, Adam,
Dear Science Team,

I'm currently preparing for the opencascade 7.4 transistion [1] and netgen
FTBFS with the new version, available in experimental.

[1] https://release.debian.org/transitions/html/auto-opencascade.html

It seems so that upstream has a fix already [2], I can confirm that it also fix the FTBFS for
the current version available in Debian:

[2] https://github.com/NGSolve/netgen/commit/18070c9f03072cadffe7baed4ba4045dd9ea680e#diff-3ee1c88f2a71a62145e31da1ef21ea3f

Attached is the build log and the patch I used to make it compile.
(Note: I did NOT check if netgen also compiles with the patch and the current opencascade 7.3)

I did also NOT test the new package, please speak up if you have concerns.

Cheers,
