mach `main` currently broken

Cloning the mach repo and trying to build examples doesn't work. This also happens when I try to build other examples as well.

git clone https://github.com/hexops/mach/
cd mach/
zig build run-example-triangle

/src/platform/c.zig:1:15: error: C import failed
pub const c = @cImport({
              ^
./zig-cache/o/4cb64c7e40f0c8be809e30e746611988/cimport.h:3:10: note: 'dawn_native_mach.h' file not found
#include <dawn_native_mach.h>

I checked the whole repo with find . | rg "dawn_native_mach.h" but no files were found.

I'm compiling with zig version 0.10.0-dev.3366+e6b3eae49 on macOS 12.4

I have a similar issue on Arch Linux. I also tried to re-clone mach and then I got

: /theodata/projects/minecraft-mods/elementalcraft/deps/mach/gpu/libs/mach-gpu-dawn/libs/dawn/src/dawn/utils/VulkanBinding.cpp:23:10: fatal error: 'GLFW/glfw3.h' file not found\

even though /usr/include/GLFW/glfw3.h exists.

Sorry for main being broken, y'all!

It was only supposed to be broken for ~24h while I landed the remainder of #403 (had to do this to get some other parts in), but I suddenly caught the flu, have been quite sick since, and then lost someone dear to me just yesterday.

In the meantime you can git checkout 36539d7c3db3e807047d457e65fc3aeb3145bafa and as long as you have a fairly recent Zig v0.10 version (0.10.0-dev.3027+0e26c6149) it should just work

I'll have it all working again soon-ish.

Should be fixed now that #403 is merged! Feel free to open a new issue if you encounter any problems.

Current main is failing to build for me. (Stumbled upon the repo and gave it a drive-by compile; don't have time to investigate, apologies.)

@sentalis no worries, thanks for the report! #454 was just merged which should fix that, we'll start testing with the latest Zig version soon (which is what caused this)

`main` currently broken - sorry all!
