Bug#1029440: opm-common: FTBFS in bookworm (cc1plus: fatal error: [...]/builtin_pybind11.cpp: No such file or directory)

[Markus Blatt]

Hi guys,

Santiago told me that the machine used for rebuilding would have enough ram.
Well, I beg to differ. At least the machine that he gave me access to only
has 2 GB of RAM and no swap space:

markus at debian-1:~$ LANG=C free
                total        used        free      shared  buff/cache   available
Mem:         1981536       80440      795168         512     1105928     1720784
Swap:              0           0           0

That makes migh highly doubt that it is possible to compile opm-common (and probably
other C++ packages using templates) on that machine. Even if the file would have been
correctly generated.

The lacking RAM is probably why I never saw this on any other amd64 build (on Debian)
as they all seem to have more RAM per build thread (I assume >=4GB). Ubuntu is another
story though (we needed to limit parallel builds for e.g. opm-simulators there before).

How should we proceed. Is there a possibility to do the builds on other machines with
more RAM?

Best,

Markus
