Arch Linux User Repository

thank!

done

I needed a small adjustment to get rid of No such file or directory #include "mlir/Dialect/Vector/Transforms/VectorTransformsEnums.h.inc"

Please bump version and change linker to lld in order to support also CachyOS (should still work on vanilla Arch).

This version is broken, see https://github.com/llvm/llvm-project/issues/160896.

What wanghaoran said: Missing keys. Even installing the key doesn't help.

missing validpgpkeys '71046D1E9C6656BDD61171873E83BABF4A4F9E85'# Cullen Rhodes cullen.rhodes@arm.com , so is flang

maybe try to uninstall any previous version of mlir first, or get rid of any cache/build files, also it takes a lot of memory if you have -jx MAKEFLAGS set in makepkg.conf

When trying to install Flang (20.1.8) on CachyOS, the mlir compile fails with

/usr/bin/ld: /usr/lib/libLLVMTableGen.a: error adding symbols: file format not recognized collect2: error: ld returned 1 exit status make[2]: *** [tools/mlir-tblgen/CMakeFiles/mlir-tblgen.dir/build.make:477: bin/mlir-tblgen] Error 1 make[1]: *** [CMakeFiles/Makefile2:15329: tools/mlir-tblgen/CMakeFiles/mlir-tblgen.dir/all] Error 2 make: *** [Makefile:136: all] Error 2 ==> ERROR: A failure occurred in build(). Aborting... error: failed to build 'mlir-20.1.8-1': error: can't build flang-20.1.8-1, deps not satisfied: mlir>=20 error: packages failed to build: mlir-20.1.8-1 flang-20.1.8-1 PAKtC

How can this be fixed / how can I provide the necessary information? From problems I've had before of linking Fortran modules, I suspect that the compiler used for LLVM is different from the compiler used to build MLIR, but I don't have enough technical knowledge to debug further / fix the problem, sorry.

@xantares

Do you think that you could switch mlir to use the Ninja backend for faster compile times? Also, please add yourself as maintainer to the top of the PKGBUILD. Furthermore, make the license() SPDX compliant.
