I'd go and take a look at the existing cross-compilation targets like musl or avr: https://src.fedoraproject.org/rpms/musl/blob/rawhide/f/musl.spec https://src.fedoraproject.org/rpms/avr-libc/blob/rawhide/f/avr-libc.spec > Some issues I have run into so far: > > - This is a libc implementation, which would probably conflict with the > glibc package by default.

See https://docs.fedoraproject.org/en-US/packaging-guidelines/#_filesystem_layout Exceptions * Fedora allows cross-compilers to place files in /usr/target. > - Clang seems to have issue with `-fstack-clash-protection` flag for the > `wasm32-wasi` target. What's the proper way to adjust these? You can filter them out. There was some discussion recently about filtering troublesome flags from Fedora default flags: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/SNV72TC5SDPUSQEVULKRKPIJE2ZMQUIP/ PS. I'm maintaining two WASM-related packages which I needed to build some Firefox extensions from source: binaryen and wabt. I'm definitely not a good maintainer for them as I know next to nothing about WASM. I'd appreciate a co-maintainer who knows a bit about WASM.
