Hi,

I tracked this pretty far:

This is a related issue that mentions the `mepo` package:
https://github.com/ziglang/zig/issues/12170

And I realized the problem comes from `pkg-config`. It's telling zig to use=
 the static library first.
Removing `pkg-config` from the `native-inputs` in your proposed package mak=
e it build but the `runpath` validation phase fails.

I'm not sure about what to do now.

In the issue the people working on freebsd-ports mention they did this:
https://github.com/freebsd/freebsd-ports/blob/16ada4d8d14a222bd92c4bf332d28=
b7c604af457/astro/mepo/Makefile#L31
But I don't know if we can replicate that.

I'll keep researching on this a little bit further.

Best,
Ekaitz

Maybe there are more flags for this, but I'm not sure.

I'm not very versed on this so I can't give you a proper answer.

Yes, it was pretty badly phrased.
The question here was about how do the Mepo devs build mepo in other
linux distributions... They should have a similar problem to what we
have. Or other systems like Nix, how do they build?
In Nix the problem should appear too.

With *directly* I meant the Mepo repository doesn't contain the
transitive dependencies so... It would never work for us, but it
should be working for them.

Reading your message before seems like they manage to link against
the SDL .so so nothing of this happens...

I'll try to check all this with the Zig people to see if we can
fix.

Thanks!

Hi,

I have good and bad news for you.

I tried to replicate the problem, and I certainly did. I also managed to mi=
tigate the problem adding `exe.linkSystemLibrary()` lines to the build.zig =
with the transitive dependencies.
And later I wondered how did this all work in GCC, just in case.

(NOTE: take in account you also need to link with libc! for that you can ad=
d it as a linkSystemLibrary("c"))

The problem is not Zig specific, look:

I tried a random example from a repo in Github using SDL2 and SDL2-Image:=
=20
https://github.com/aminosbh/sdl2-image-sample/blob/master/src/main.c

Made a shell for it:

guix shell sdl2 sdl2-image gcc-toolchain glibc:static

And tried to build:

$ gcc a.c -static -lSDL2 -lSDL2_image -lm -lc 2>&1 | head

The list of errors are basically the same you have.
Zig builds statically if I'm not mistaken so it's triggering the same probl=
em GCC would for that case.

We need to research this further...

I also checked Mepo, how do they manage to build directly?

I don't have the Zig knowledge to know how does all this work, but I know i=
t's not just the build-system's fault because it happens in GCC too, and al=
so with a normal shell with `zig` available, and running the command by han=
d. The build-system just replicates that behavior.

We need to dig on this further. Are you, Nguy=E1=BB=85n, a Zig programmer? =
Maybe you can help me figure out this?

Thanks for the report, the patience and the help!

All the best,
Ekaitz

I am trying to package Mepo, an OpenStreetMap frontend written in Zig.
The currently packaged Zig fails to find transitive dependencies of SDL2:
https://paste.sr.ht/~cnx/db21e1ef9a6828f3ec898db43b790d71b5ef213a

Here's a minimal reproducible Zig project:

// main.zig
const c =3D @cImport(@cInclude("SDL2/SDL.h"));
pub fn main() !void {
    if (c.SDL_Init(c.SDL_INIT_VIDEO) !=3D 0)
        return error.SDLInitializationFailed;
    c.SDL_Quit();
}

// build.zig
pub fn build(b: *@import("std").build.Builder) void {
    const exe =3D b.addExecutable("sdl2-smoke-test", "main.zig");
    exe.linkSystemLibrary("SDL2");
    exe.setTarget(b.standardTargetOptions(.{}));
    exe.setBuildMode(b.standardReleaseOptions());
    exe.install();
}

For convenience, here goes a manifest for use with guix build -f:
