[pikatchu]

You probably ran out of memory.

[cnd]

@pikatchu no, I have enough memory

[pikatchu]

It's going to be difficult for me to debug just like that.

What made me think of an out of memory issue is that I had a similar problem when trying to compile in a docker image.

I realized after the fact that docker has a setting that limits the overall memory that can be used by docker containers (setup to 2 Gigs by default). So I had to go into the GUI menu of my mac to fix it (using the command line -m thing did not help).

What is your config? Are you using ubuntu?
I will need a lot more details to help you here ...

[cnd]

@pikatchu gentoo, gcc 8.2.0, llvm 7, 16gb ram, please ask what exactly info you need

[cnd]

@pikatchu there is ebuild (source based package) I'm trying to use/develop for that project https://github.com/Heather/gentoo-cynede/blob/master/dev-lang/skip/skip-9999.ebuild

[pikatchu]

Gotcha.

Was anything else failing? How did you run cmake? Was it release or debug?
Could you copy paste what commands you ran? Thanks!

[pikatchu]

Sorry I am not familiar with ebuild ... But I will try to make sense of it!

I've seen this when the build modes are somehow mismatched - SKIP_Obstack_note_inl only appears as a real symbol in certain cases - it's expected to be inlined in the preamble.ll
