i take the liberty to add some dependencies described in the build process. can remove it if not need at all

greetings

oh. i missread how build dusckstation their dependencies (normally this type of projects use gitmodules, but is not the case). let me check again your new pkgbuild posted below

greetings

you not need build separately shaderrc in the pkgbuild, let duckstation build it when use their build environment.

let me time and i craft the pkgbuild for you

greetings

@sl1pkn07 I'm not sure it is possible.
Locally I modified PKBUILD to build shaderc as part of the package and to place it alongside duckstation binary. But implementation is rather ugly, and uses patchelf to mess with embedded paths.
To those who are curious: https://pastebin.com/hcy7FraF

better make shaderrc with that custom patch as static library and build duskstation against it

greetings

@Niinu Reason for addition is this commit: https://github.com/stenzek/duckstation/commit/59eeb892432c587f3bff0400b93c26291c61ba05
Without shaderc-non-semantic-debug package build fails.

The added shaderc-non-semantic-debug conflicts with shaderc that's a dependency of libplacebo which is a dependency of ffmpeg. Why is a patched shaderc package that only additionally outputs debug information needed?

Since commit https://github.com/stenzek/duckstation/commit/12a24b9faec1d472b37b86efa2ea46842deed26d build fails on linking.
