The log of fetch_dawn_dependencies is suspicious and lacks multiple dependencies. I think the hint is the message "Overridden by a local copy of the submodule", which I believe means that dawn source is cloned with submodules, which it shouldn't. Could you check what the file tree in C:/dev/webgpu-test/build/_deps/dawn-src/third_party looks like? Do you have folders containing only a .git directory?

I tried another machine and it works, I'll try again when I get to my other machine

I meant the content of directories as well, in particular whether there is a .git in e.g., abseil-cpp, and where there is a CMakeLists.txt.

Maybe your git is globally setup to always get submodules? You should make sure not to clone submodules when cloning Dawn.

imadr commented 5 months ago

The sub directories are empty. How is dawn supposed to be compiled without the submodules? I tried compiling this repo https://github.com/beaufortfrancois/webgpu-cross-platform-app and had a similar issue until I pulled all the dependencies

imadr commented 4 months ago

For those having the same problem, the solution I found is manually running the script dawn\tools\fetch_dawn_dependencies.py

eliemichel commented 4 months ago

Yes indeed it is that script that is supposed to ensure that dependencies are ready. The WebGPU-distribution files should turn on the CMake option DAWN_FETCH_DEPENDENCIES in order to have this script ran automatically.

If it does not, try forcing this option by adding -DDAWN_FETCH_DEPENDENCIES=ON while calling CMake configuration (or use cmake-gui).

Marking this as resolved since you have a workaround, but if one reads this later and experience the same issue of DAWN_FETCH_DEPENDENCIES not being on by default let us know!
