Cannot build on MacOS

[Gerharddc]

Hi, I have a Zig 0.16 project using this library that compiles and runs perfectly on Linux. However, when I try to compile it on MacOS (15.6.1), I run into the following issue:

m1@28587c3e-cc2f-4f54-bced-1184e6e74cad vk-zig % zig build run
/Users/m1/vk-zig/zig-pkg/sdl-1.0.1+3.4.4-i4QD0QCGqQC6Myg3SmNw5dry28oQHFOZW0V7aN7wIV3v/build.zig.zon:52:20: error: failed to create temporary zip file: FileNotFound

                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any ideas what could be causing this and how to possibly fix it?

Hey! This is a bug in Zig 0.16, it’s been fixed in master but hasn’t made its way into a release yet.

You can work around it by creating the missing tmp directory with mkdir -p ~/.cache/zig/tmp. Or at least that’s the workaround on Linux—I assume the paths on macOS are the same, but don’t have a Mac in front of me to test with let me know if this doesn’t work or if you hit any other build issues on macOS.

A few people have run into this so I’m going to leave this issue open to remind me to look into whether this only affects zip files. If so, I can just change the dependencies to use tar files or git to save people the confusion.

Ah I see, the suggested workaround solves the problem. Thanks @MasonRemaley !

No problem! It looks like this only affects zip files, so I went ahead and switched the two .zip deps to tar.gz to save others from running into this.
