Zig module not found in main module

Help
1

I am trying (similar to here: Zig module not visible after import) to import the zig-clap module as provided in the readme, but when I try to compile the program with

zig run main.zig

I get the error message:

main.zig:2:22: error: no module named ‘clap’ available within module main
const clap = @import(“clap”);

I followed the example in the readme file and it should work.

EDIT:
I found out, that clap is not actually in my project…, it is located (for some reason) in the AppData folder of Windows (in the zig directory), but it is still not working

EDIT-2:
The issue should be, that i get an error when I try to fetch the dependency…, I think cloning the repo is the solution

EDIT-3:
It is not the solution…, I’m lost now

EDIT-4:
I found out, that the issue is within the package itself because of this error:
..\zig-clap\build.zig.zon:2:14: error: expected string literal
.name = .clap,

Is it in that case a problem of the module?

What does your build.zig file look like? To reference a module by name, you need to addImport(...) to your module.
https://ziglang.org/documentation/master/std/#std.Build.Module.addImport

You will also need to add it as a dependency, which can be done with zig fetch

If you are doing it with zig run and no build.zig file, then you will have a harder time of it.

Can you run zig build, and then find and run the executable normally from the zig-out directory?

I am a newbie in zig so I may be wrong, but I don’t think zig run main.zig will run the build.zig.

The zig run command builds and runs a single Zig file. If you want a module included you can add it with zig run command line arguments, but likely you just want to use zig build with a build.zig file as others are suggesting.

Can you reply instead of editing your post, so we can follow what you are doing?

zig run builds and runs a single file, you can add modules via arguments however you should be using zig build with a build.zig

You should be using zigs package manager instead of downloading dependencies yourself.

What error are you getting when fetching the dependency

the string literal error is because the version of clap you are using is for latest zig, either update zig or downgrade clap

This might be it, because everything else “should” work. I’ll try to get the Zig version correct! Thank you

I just found out, the version of the module is compatible with version 0.13.0, is it time for an issue? I don’t think the issue is with Zig anymore

What error message do you get?
What is your build.zig.zon?
What is your build.zig?
What is your zig version?

I solved it, version 0.9.1 is not working even tho it should, but version 0.9.0 is working just fine, so there is an issue within the module itself I think

The error I got with 0.9.1 was:
…\zig-clap\build.zig.zon:2:14: error: expected string literal
.name = .clap,

The 0.9.1 release of zig clap definitely uses a string for name, so I think you mixed up something on your end.

But good that it works now.

I had some further issues, but in the end I found out I’m just stupid, I used the link with tar even tho I’m on Windows…

zig doesn’t use system tools, there is tar support in std, and you’re downloading the src code.
so unless they omitted windows code in the tar it should work

Interesting, well, I did correct it to .zip and everything seemed to work
