How to generate scripts for a currently unsupported platform with `niminst`? #24414

Open barracuda156 opened 1 week ago

Summary

Could someone explain (or refer to a documentation) how exactly to use niminst to generate build scripts for a currently unsupported platform? I need that for csources to begin with, and then for Nim.

Description

The context: I have a PR for initial support of Darwin PowerPC (it is WIP, cannot be merged yet): https://github.com/nim-lang/csources_v1/pull/7 I did some manual patching back then, but it is not the right way to go. I was able to compile niminst from source on a arm64 Mac, but cannot figure out what to do to generate w/e needed for PowerPC.

Assuming the setup is already covered by compiler/platform.nim (check!), you need to edit compiler/installer.ini and then run niminst. Then inside csources_v2 run push_c_code.nim that assumes your nim that was used for niminst is in ../nim2! But you can also edit this push_c_code.nim program or do what it does manually.

Note that macosx: i386;amd64;powerpc64;arm64 is already listed in installer.ini. I think you want macosx: i386;amd64;powerpc64;powerpc;arm64 instead.

@Araq Thank you for responding!

Yes, that I have done. We also need an alternative way to decide on the build arch for powerpc, since a) uname -m returns Power Macintosh and not the arch name, and b) even using correct uname -p does not really help, since it cannot differentiate between ppc and ppc64 (either can be built at least on 10.5.8 on G5 machine). I might have amended the script in a way build arch gonna be respected, but need to sort out generating scripts from templates first.
