I can run/build/init. I just cant import
I get this weird message already mentioned in github issues:

A Simple Example of Calling a C Library from Zig

I’m a newcomer to Zig, but I met Andrew Kelly and several other Zig developers at Handmade Seattle this week, and it motivated me to start experimenting with the language. I had a hard time finding simple, complete documentation about how to call C code from Zig. I pieced together a solution from a few different sources and then documented what...

Can you be a bit more specific on what you mean by "import"?
Do you mean "using @import" ?
If so, on what and in what file?

#

That strange message is I think what the default zig init produces in the generates main.zig.

#

It's a hello world message essentially, IIRC

i really tested a few other examples but either there is an error or weird output message i mentioned at the start of this post

#

if there is an easy import/include test if it works let me know, i really think i cant do stuff on wsl

#

oh zig build install worked but the same output

compact dragon Mar 2, 2024, 11:31 AM

#

It seems to me that your build.zig needs fixing.

#

Generally, you do something like

const optimize = b.standardOptimzeOptions();

const exe = b.addExecutable(.{
    .target = optimize,
    ...
};

noble vapor Mar 2, 2024, 11:32 AM

noble vapor oh `zig build install` worked but the same output

compact dragon Mar 2, 2024, 11:32 AM

#

zig run does not use build.zig.

noble vapor Mar 2, 2024, 11:32 AM

#

hmm

compact dragon Mar 2, 2024, 11:32 AM

#

zig build run

noble vapor Mar 2, 2024, 11:32 AM

#

sorry i post ss

compact dragon Mar 2, 2024, 11:33 AM

#

Wait

#

So zig build run works

#

But zig build doesn't?

noble vapor Mar 2, 2024, 11:33 AM

#

zig build produces no output

#

didnt work before becaue i didnt do zig build install

#

oh no

#

i was not in the directory ( i was testing something else before )

#

sorry

please take a look if this works on your end:

A Simple Example of Calling a C Library from Zig

If the goal is to be as simple as possible, I suggest you can even have no C header file. pgcd.c: unsigned int pgcd(unsigned int l, unsigned int r) { while (l != r) { if (l > r) { l = l - r; } else { r = r - l; } } return l; } Now, use-pgcd.zig: const std = @import("std"); const c = ...

ill try how it works on windows 11 without wsl

This is a successful run of the example main.zig file generated by zig init. Look in src/main.zig and you will find the weird message. What were you expecting to see?

compact dragon Mar 2, 2024, 12:36 PM

#

compact dragon Generally, you do something like ```ts const optimize = b.standardOptimzeOptions...

^

#

zig build will produce no output if it succeeds.

noble vapor Mar 2, 2024, 12:52 PM

#

civic maple This is a successful run of the example main.zig file generated by zig init. Loo...

no? there is no mention of that, well whatever im doing something else, ill try to fix it myself

#

compact dragon Mar 2, 2024, 1:00 PM

#

It's ultimately the file in the build.zig that matters.

#

Double check that is that main.zig

noble vapor Mar 2, 2024, 1:02 PM

build.zig

const std = @import("std");
const raylib_build = @import("libs/raylib/src/build.zig");
pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});
    const raylib = raylib_build.addRaylib(b, target, optimize, .{});
    const exe = b.addExecutable(.{
        .name = "hello",
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });
    exe.linkLibC();
    exe.linkLibrary(raylib);
    exe.addIncludePath("raylib/src");
    exe.install();
    const run_cmd = exe.run();
    run_cmd.step.dependOn(b.getInstallStep());
    if (b.args) |args| {
        run_cmd.addArgs(args);

    const run_step = b.step("run", "Run the app");
    run_step.dependOn(&run_cmd.step);
    const exe_tests = b.addTest(.{

        .optimize = optimize,
    });
    const test_step = b.step("test", "Run unit tests");
    test_step.dependOn(&exe_tests.step);

why is it so hard

seems like there is no working import/cImport/include for my machine

Yeah was going to say

#

That looks fine enough to me

noble vapor Mar 2, 2024, 1:17 PM

nvm it didnt work

compact dragon Mar 2, 2024, 1:20 PM

#

noble vapor

You're still getting these errors?

noble vapor Mar 2, 2024, 1:20 PM

#

well yk i have no idea how to fix copy paste different tabs and formatting on wsl ill just give ss

#

#

@compact dragon

compact dragon Mar 2, 2024, 1:21 PM

#

Ah-ha!

#

That's actually the same thing I just fixed on my project

#

Basically

noble vapor Mar 2, 2024, 1:21 PM

#

lol

compact dragon Mar 2, 2024, 1:21 PM

#

That's Raylib's build.zig not being up to date enough for master zig

noble vapor Mar 2, 2024, 1:21 PM

#

0.12 version?

compact dragon Mar 2, 2024, 1:21 PM

#

Go into raylib/src/build.zig and change the declaration of srclib to just be

const srcdir = "src";

#

(I vendored raylib, so I can just do that)

#

[Edit: correct path lol]

noble vapor Mar 2, 2024, 1:23 PM

#

ah... i forgot to even clone raylib but lets see if it changes sometihng on windows

compact dragon Mar 2, 2024, 1:24 PM

#

[Edit: correct variable name lol]

noble vapor Mar 2, 2024, 1:26 PM

#

const srcdir = struct {
    fn getSrcDir() []const u8 {
        return std.fs.path.dirname(@src().file).?;
    }
}.getSrcDir();```


->

```ts
const srcdir = "src";

?

compact dragon Mar 2, 2024, 1:26 PM

#

Indeed

noble vapor Mar 2, 2024, 1:27 PM

#

#

oh not in this directory ig

#

#

@compact dragon

#

what is this rcore.c?

#

0.12.0-dev.3125+a7a5f4cf4```

compact dragon Mar 2, 2024, 1:29 PM

#

noble vapor <@201094465815969794>

It's one of Raylib's C files that Zig will build.

compact dragon Mar 2, 2024, 1:29 PM

#

noble vapor

That makes me think that it didn't actually use the file you changed

noble vapor Mar 2, 2024, 1:30 PM

#

lets clear cache then

#

no

#

https://github.com/SimonLSchlee/zigraylib
this is what ive used

GitHub

GitHub - SimonLSchlee/zigraylib: a fairly minimal raylib zig exampl...

a fairly minimal raylib zig example codebase using the zig package manager - SimonLSchlee/zigraylib

#

idk probably im doing just something really dumb

#

oh right

#

it fetches probably from the github repo

#

not the local file

#

well

#

can you give me some code i can test on?

#

all the code ive found is outdated (for raylib)

compact dragon Mar 2, 2024, 1:33 PM

#

When I said I vendored it

#

I mean that I cloned the upstream Raylib repo

#

And then put this in my build.zig.zon:

.dependencies = .{
    .raylib = .{
        .path = "pkg/raylib",
    },
},

Where pkg is just a folder of my choosing

noble vapor Mar 2, 2024, 1:34 PM

#

+ git submodule add https://github.com/raysan5/raylib.git 
or
- git clone https://github.com/raysan5/raylib.git

noble vapor Mar 2, 2024, 1:35 PM

#

compact dragon And then put this in my build.zig.zon: ``` .dependencies = .{ .raylib = .{ ...

im not good enough to understand that

compact dragon Mar 2, 2024, 1:35 PM

#

I used git subtree
Something like git subtree add --prefix pkg/raylib https://github.com/raysan5/raylib.git master

noble vapor Mar 2, 2024, 1:35 PM

#

i really just want to import "a" library, raylib may be too challenging

#

becasue it seems like nothing is working

#

the most minimal test

compact dragon Mar 2, 2024, 1:36 PM

#

You should have a build.zig.zon next to your build.zig

noble vapor Mar 2, 2024, 1:37 PM

#

    .name = "zigraylib",
    .version = "0.0.1",
    .dependencies = .{
        .raylib = .{
            .url = "https://github.com/raysan5/raylib/archive/e52ae870f297961b9ac23d2e6eca4937a24ac6c0.tar.gz",
            .hash = "1220b9dc848ba1359453ce8a68fa844bcbc2cacda462b47498f12d3fd932c63390ee",
        },
    },
    .paths = .{
        "build.zig",
        "build.zig.zon",
        "README.md",
        "src",
    },
}```

compact dragon Mar 2, 2024, 1:37 PM

#

If you want to vendor raylib

#

Then change use .path instead of .url, and remove .hash

#

Or yeah - that is what zigraylib's build.zig.zon looks like

#

I started out using some sort of helper zig package for raylib, but it wasn't that great, so I switched to just using upstream raylib

noble vapor Mar 2, 2024, 1:39 PM

#

idk...

#

isnt there a working code for raylib

#

so i can just copy and test

#

dont you have a workign project

#

or something

#

@compact dragon

compact dragon Mar 2, 2024, 1:40 PM

#

I do, but alas it's not public code.

noble vapor Mar 2, 2024, 1:40 PM

#

hm

compact dragon Mar 2, 2024, 1:40 PM

#

And I've already told you the important parts anyhow

#

The only part I don't quite remember is the exact git subtree command I used

compact dragon Mar 2, 2024, 1:41 PM

#

compact dragon I used `git subtree` Something like `git subtree add --prefix pkg/raylib https:/...

But it was along these lines

#

Might be main instead of master - I forget what name they use

noble vapor Mar 2, 2024, 1:41 PM

#

ok ill just wont import stuff

#

my use for zig isnt that big

#

and this is too complicated and time consuming

#

thank you for your help

compact dragon Mar 2, 2024, 1:42 PM

#

Alright o7

halcyon goblet Mar 2, 2024, 1:45 PM

#

lol

#

I would absolutly recommend against using git submodules

#

in this case it's a case of updating the dependency

#

for my raylib example which it was the original test, I only had to do zig fetch https://github.com/raysan5/raylib/archive/25caf14be8d0284aceaa0de28753b3012e71b7bb.tar.gz --save=raylib
