Arch Linux User Repository

reading through the rest of the comments here, this looks like the same problem from 2021 that oxplot was dealing with.

I added a comment to the project issue tracker with a possible fix: https://github.com/pcb2gcode/pcb2gcode/issues/587#issuecomment-3122004254

Same issue as evgenuel. I was able to get it to compile with:

I think it's related to the use of '-isystem' in the project's configure.ac, but I don't know if it's possible to thread the environment variables from autoconf into cmake somehow. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70129#c5

Turns out it was OOM killer that messed up the build. I have 12GB RAM and needed to add 12GB swap to make it compile due to massive parallel compilers.

This does not compile for me,

git protocol on github seems to no longer be working. Maybe it should be changed to git+https?

Submitted a bug report here: https://github.com/pcb2gcode/pcb2gcode/issues/587

Downgrading to boost and boost-libs 1.76.0.1 seems to make this program work again.
