Help with building Raylib

Judsen · March 18, 2024, 4:05am

Hey need some help getting raylib to work.
I’m trying to work off of a sample project.
Here is a github link. GitHub - JudsenHembree/raylib-zig

I am running wayland and am getting these macro errors with raylib. I’m operating under the assumption that I need to define these macros when building? How would I do that with zig build?

Or perhaps it’s something different.

Thanks for the help.

Hi @Judsen, welcome to ziggit

Perhaps the posts in this thread, about versions and recent changes, can help:

Sze · March 18, 2024, 2:22pm

So far I haven’t used wayland.
Here is a general plan of what I would do in your situation:

create a local clone of raylib GitHub - raysan5/raylib: A simple and easy-to-use library to enjoy videogames programming
take a look at CMake Build Options · raysan5/raylib Wiki · GitHub
which shows the USE_WAYLAND option
now we need to add a use_wayland option to the build zig
- open the file raylib/src/build.zig at master · raysan5/raylib · GitHub in your local clone
- add a new use_wayland option here raylib/src/build.zig at 28c232d856e8908a9f2675d5df56bc16f1e30acf · raysan5/raylib · GitHub and here raylib/src/build.zig at 28c232d856e8908a9f2675d5df56bc16f1e30acf · raysan5/raylib · GitHub
- use the option, here raylib/src/build.zig at 28c232d856e8908a9f2675d5df56bc16f1e30acf · raysan5/raylib · GitHub by adding an if (options.use_wayland) raylib.defineCMacro("USE_WAYLAND", null);
now in your local application change the build.zig.zon
- remove the fields url and hash from the raylib dependency
- add a path field with the path to your local raylib checkout
using the option in the build.zig
- now locally add .use_wayland = true, here raylib-zig/build.zig at c4c4cbb4853dc13c95c47c672e38f473c33a6424 · JudsenHembree/raylib-zig · GitHub

I think that should work, can you try if this works for you?

Searching for Code search results · GitHub
I think you will have to use something like:

if (options.use_wayland) {
    raylib.linkSystemLibrary("wayland-client");
    raylib.linkSystemLibrary("wayland-cursor");
    raylib.linkSystemLibrary("wayland-egl");
    raylib.linkSystemLibrary("xkbcommon");
    raylib.defineCMacro("USE_WAYLAND", null);
}

Judsen · March 18, 2024, 5:04pm

Good the author has replied lol. This was as close I could get to a dm lol.

I will try your debugging tonight. Thanks a bunch.

What you’ve shown seems plausible though.

Judsen · March 18, 2024, 9:48pm

tldr; No dice. Added these macros -DCUSTOMIZE_BUILD=1 -DUSE_WAYLAND=1 -DGLFW_BUILD_WAYLAND=1 -D_GLFW_WAYLAND=1 and tried to link wayland-client lib, but I’m just guessing at how to fix this. I did some research into the source code and haven’t been able to get it working yet.

Here is the build.zig for raylib where I add said macros.

                if (options.use_wayland) {
                    raylib.linkSystemLibrary("wayland-client");

                    raylib.defineCMacro("CUSTOMIZE_BUILD", null);
                    raylib.defineCMacro("USE_WAYLAND", null);
                    raylib.defineCMacro("GLFW_BUILD_WAYLAND", null);
                    raylib.defineCMacro("_GLFW_WAYLAND", null);
                } else {
                    raylib.linkSystemLibrary("X11");
                    raylib.defineCMacro("PLATFORM_DESKTOP", null);
                }

Here is my progress.

So I researched this macro you mentioned. USE_WAYLAND as far as I can tell from trying to grep it from the repo that documentation is defunct. It is not in the CMakeOptions.txt file mentioned.

So I looked for some alternatives and found some other wayland based flags. I tried to turn those on and got some different output.

So sure enough I don’t have that header file in /usr/include, however I’m having trouble finding it online.

It may be the case that I’m ahead of wayland development for raylib. If you are aware of how to get this header file do let me know. I will update this thread if I can get it working.

Thanks again,

github link again GitHub - JudsenHembree/raylib-zig

Judsen · March 18, 2024, 10:46pm

update:

I found some code. Seems important to generating that header file. Haven’t got it to work yet. raylib-zig/raylib/src/external/glfw/src/CMakeLists.txt at f4ff225cab0c384c38c8bad9f1d723c02ce140dc · JudsenHembree/raylib-zig · GitHub

Hmm it seems the wiki is old, apparently USE_WAYLAND has been removed and now there is the GLFW_BUILD_WAYLAND option in the glfw cmake file CMake: Remove USE_WAYLAND option by M374LX · Pull Request #3851 · raysan5/raylib · GitHub

I kind of wish raylib was bold enough to ditch cmake entirely and do everything with zig only, that way nobody would have to deal with cmake, but I guess a lot of c users are still used to it and using it, so sadly it is kind of unlikely.

Maybe it would make sense to try to build the library with cmake and then maybe use some verbose logging option to see what it ends up doing and then copy that with Zig?

Alternatively you could just build (possibly via cmake) a wayland raylib shared library and link to raylib dynamically. That is what I did before I used raylib as a zig dependency (minus the wayland part).
But I guess as soon as you got a working cmake wayland build there should be a way to replicate that with zig.

Sze · March 19, 2024, 12:43am

Have you tried simply updating the url+hash to the latest raylib commit?
The conversation here Fix GLFW runtime platform detection by M374LX · Pull Request #3863 · raysan5/raylib · GitHub combined with this: raylib/src/build.zig at 9cf408f77c58828fd1019d5cd35c6b8c5139c8dc · raysan5/raylib · GitHub

This here raylib/src/rglfw.c at master · raysan5/raylib · GitHub

rglfw - raylib GLFW single file compilation

This file includes latest GLFW sources (GitHub - glfw/glfw: A multi-platform library for OpenGL, OpenGL ES, Vulkan, window and input) to be compiled together
with raylib for all supported platforms, this way, no external dependencies are required.

Makes me think that updating to the newest version, should automatically get you a build that contains the different possible platforms and that automatically selects between x11 and wayland at runtime, but it also seems that this has been added relatively recently so it still might not be in my last version bump.

Judsen · March 19, 2024, 2:01am

I cloned master today, So I don’t believe that getting the most recent url/hash will perform any different.

Update: I can build with cmake

Judsen · March 19, 2024, 2:25am

I think I need to do this in zig for it to work. I’ll look into zig subprocess calls.

Something like Zig Build System ⚡ Zig Programming Language

Judsen · March 21, 2024, 5:38am

More progress but still not quite there.

I can now generate those files, but I’m getting undefined references still. I’m failing to link the libraries correctly somehow.

Github updated if anyone is following along.

If you look at this it says Wayland API (experimental and incomplete):

I think it would make most sense to get in contact with the people working on that wayland support and see if you can help them, if you want to do that, I think that would be more productive than trying to brute force your way there on your own.

So my suggestion would be to go on the raylib discord and ask there who works on wayland support and if you can join them / whether they have tricks or tips for you.

Another option would be to use something like Xwayland to run an x11 application on wayland. (Until the wayland support is stable)

Fair enough.

I can do that. Thanks for the help.

Judsen · March 23, 2024, 7:21pm

We got there in the end.

Nice work.
What mysteries did you uncover and what did you do to make it work?

Judsen · April 12, 2024, 4:15am

Apologies for leaving you hanging. Haven’t browsed the site recently.

I was a single macro off of compiling successfully. Once I swapped that in I was good to go. I believe it was the PLATFORM_DESKTOP one.

Do let me know if you ever want to review/merge my changes into your build.zig. I’ll go clean them up.

But I imagine wayland users are few and far between.

Sze · April 12, 2024, 6:31am

Upstream raylib had a few changes, its build.zig now has options for x11 and wayland, I haven’t updated yet but will soon, maybe with that it will just work.

But one thing that I think is still missing (last time I checked) from raylib’s build.zig is to be able to pick both x11 and wayland (so the executable can pick at run time, raylib has some kind of platform detection).
That might be useful when you want to share builds, but doesn’t really matter when compiling locally.
