Created attachment 799467 [details]
nodejs build log and emerge --info

I cannot crosscompile net-libs/nodejs-18.7.0 for arm64

I'm using crossdev with default/linux/arm64/17.0 profile. 

My CHOST and CBUILD:
CHOST=aarch64-unknown-linux-gnu
CBUILD=x86_64-pc-linux-gnu

I'm attaching log with build errors and aarch64-unknown-linux-gnu-emerge --info

Can you try passing --cross-compiling?

[Comment 3 ev 2022-08-16 11:19:29 UTC]

I've tried using --cross-compiling flag in nodejs-18.6.0 and nodejs-18.7.0 ebuilds. But flag does not help.

This is a link to ebuild I've used for test (version 18.6.0).

Any updates on this issue?
I have similar problem cross compiling nodejs:

This is kind of different because the qemu failure is because of a misconfigured qemu-user setup. But indeed the root issue of trying to run a just built binary is still there.
