Isaac Van Doren (Jan 10 2024 at 04:49): Isaac Van Doren (Jan 10 2024 at 04:49):I am running on apple silicon with Zig 0.110 and w4 2.6.1.
When I try zig build run or run-native, I get this error
0 errors and 0 warnings found in 19 ms.
0 errors and 0 warnings found in 137 ms while successfully building:

Any suggestions to fix this?
Isaac Van Doren (Jan 10 2024 at 04:53):My Zig cache looks like this
app.wasm h o tmp z
What is the name of your .roc file? You will need to use -Dapp=path/to/roc/file.roc to tell zig to build a different file. zig build will default to the snake example
Luke Boswell (Jan 10 2024 at 05:43):Or are you literally just writing zig build and you get this error?
Luke Boswell (Jan 10 2024 at 05:43):This line looks interesting to me zig build-lib cart Debug wasm32-freestanding: error: warning: FileNotFound: /Users/isaacvando/Desktop/projects/roc-wasm4/zig-cacheapp.o I would expect to see an slash after the zig-cache and before app.o
Luke Boswell (Jan 10 2024 at 05:48):Can you confirm in your build.zig you have this line lib.addObjectFile(.{ .path = "zig-cache/app.o" }); and the slash is there? If I remove that I get an identical error to you (also apple silicon with the same versions)
Luke Boswell (Jan 10 2024 at 05:50):Other than that I'm not sure what this could be, hopefully Brendan will have some ideas
Brendan Hansknecht (Jan 10 2024 at 06:45):try updating roc
Brendan Hansknecht (Jan 10 2024 at 06:46):zig-cache/app.wasm
should say zig-cache/app.o in lastest roc (hopefully that is in the nightlies now)
Luke Boswell (Jan 10 2024 at 06:50):Oh yeah, I forgot about that. Thanks @Brendan Hansknecht
Isaac Van Doren (Jan 10 2024 at 14:02):Ah yeah that was it :sweat_smile:. Thank you!
I opened up a PR to add the "version" of Roc required https://github.com/lukewilliamboswell/roc-wasm4/pull/8
