Libc not linking when compiling for emscripten

CashWasabi · July 8, 2024, 12:13am

Hey everyone, I have been trying for a while now to compile chipmunk2d for emscripten.
For some reason I am not able to to it though because I always get errors indicating that I didn’t link libc (stdlib.h can’t be found etc.).
I’m using the following command below which is causing said issue. When building for non wasm targets it is working though.

zig build run-basic -Dtarget=wasm32-emscripten --sysroot ~/.emscripten_cache

Below is a link to the gist containing the build.zig and an emcc.zig file. I took some inspiration from raylib-zig and the raylib project.
Something to note is that I am using exe_lib.linkLibC().
Also I tested it on 0.12.1 and 0.13.0
link to build.zig and emcc.zig

If it helps this is the stacktrace:

run-basic
└─ run emrun
└─ run emcc
└─ zig build-lib basic Debug wasm32-emscripten 32 errors

Hi

Here are my notes on debug this sort of stuff

#to compile main.zig with the C standard library and your library in …/c_src
zig run main.zig -lc -I …/c-src/

Hope it helps

const module = b.addModule("root", .{
        .root_source_file = b.path("src/chipmunkz.zig"),
        .link_libc = true,
    });

I didn’t know that this option exists. Thank for making me aware of it!
I did try it with the flag set to true but it still doesn’t work.
Someone in the Zig discord said it might be because libc doesn’t get shipped with emscripten and only with wasi so I might need to look into that.

CashWasabi · July 8, 2024, 9:59am

Hey, thanks for the tip! You’re right, maybe I should first try to compile it without a build.zig and then try to translate it afterwards.

I think you are missing this part:

github.com

raysan5/raylib/blob/9764fef26260e6fcf671ddffb230360cc1efa1f8/src/build.zig#L203C13-L212C71


      
          if (b.sysroot == null) {
              @panic("Pass '--sysroot \"$EMSDK/upstream/emscripten\"'");
          }
          
          const cache_include = std.fs.path.join(b.allocator, &.{ b.sysroot.?, "cache", "sysroot", "include" }) catch @panic("Out of memory");
          defer b.allocator.free(cache_include);
          
          var dir = std.fs.openDirAbsolute(cache_include, std.fs.Dir.OpenDirOptions{ .access_sub_paths = true, .no_follow = true }) catch @panic("No emscripten cache. Generate it!");
          dir.close();
          raylib.addIncludePath(.{ .cwd_relative = cache_include });

It manually adds the include path to <sysroot>/cache/sysroot/include.
I think using b.pathJoin makes that a bit simpler, I am using:

const sysroot_include = b.pathJoin(&.{ b.sysroot.?, "cache", "sysroot", "include" });
var dir = std.fs.openDirAbsolute(sysroot_include, std.fs.Dir.OpenDirOptions{ .access_sub_paths = true, .no_follow = true }) catch @panic("No emscripten cache. Generate it!");
dir.close();

exe_lib.addIncludePath(.{ .cwd_relative = sysroot_include });

This is using a --sysroot that is specified via an absolute path, I am not sure whether that is best practice, but this is what the raylib build.zig does currently.

That’s it! I was circling around thousand other things and completely forgot about that part. Thank you so much! I’ve been banging my head against a wall for days now. It’s compiling now! Next thing will be to clean up the whole thing.
