Nix Derivation: libgc.a

[tengkuizdihar]

V version:
OS: NixOS

What did you do? Mind you I'm not too familiar with the C buildsystem.

I'm trying to build vlang with a nix derivation but I'm having trouble with linking libgc.a. After some discussion, we decided to link libgc of our own instead of using what's provided locally via thirdparty/tcc. Is there a way to do that? This piece of code tells me that you can use gc.o instead. I think I need to disable tinyc (how?) in the buildsystem.

What did you expect to see? v is able to build build-tools, vdoc, vvet, etc.

What did you see instead?

安装aarch64-linux-gnu，重aarch64-linux-gnu安装路径复制，libgc.a

[tengkuizdihar]

ok, just did a translation for that, but you do realize I'm not on Ubuntu but on Nixos right? using the nix ecosystems?

[xiaojin20]

用find命令 全系统， 搜索libgc.a 这文件在安装gcc时，是默认安装的。

@tengkuizdihar hey, I ran into the same error, and found the libgc.a file I'm now going through another error, my efforts so far are at https://github.com/NixOS/nixpkgs/pull/231959 If you have any ideas, feel free to post anything.

[tengkuizdihar]

its on nixpkgs now.

If anyone still wanna build from source (works on termux android and all derivative):

1. Run make (as usual)
2. Examine the make output, as soon as it says cc -std=gnu99 -w -o v1.exe ./vc/v.c -lm -lpthread,
3. Hit CTRL-Z
4. cd v/thirdparty
5. git clone https://github.com/vlang/tccbin --branch thirdparty-linux-aarch64 tcc. Customize this to your device. See here for available branches.
6. fg
7. Profit. This fixed no libgc.a error for me (You still need working cc installed tho)
