MSYS2/UCRT64: LINKER_TYPE 'MOLD' is unknown or not supported by this toolchain. #1267

Closed Tyler799 closed 4 months ago

Tyler799 commented 4 months ago

GCC Version: 14.1.0 CMAKE Version: 3.29.3 MOLD Version: 2.30.0 (mingw-w64-ucrt-x86_64-mold)

I am attempting to swap in Mold as the linker for an existing cmake project. I'm running cmake using:

-DCMAKE_EXE_LINKER_FLAGS="-fuse-ld=mold" -DCMAKE_SHARED_LINKER_FLAGS="-fuse-ld=mold"

(I have also tried setting CMAKE_LINKER_TYPE instead, same issue)

That causes the following error:

CMake Error in C:/Users/tyler.shellberg/Documents/build/myProject/CMakeFiles/CMakeScratch/TryCompile-4y8fvv/CMakeLists.txt:
  LINKER_TYPE 'MOLD' is unknown or not supported by this toolchain.

The minimum cmake is set to: cmake_minimum_required(VERSION 3.16...3.29) and the error happens the moment it hits the project keyword.

mold is in my path.

mold supports the ELF file format only; it does not support PE/COFF that is used by Windows. You cannot use mold for MinGW.

I'm confused, then why why there a Mold package for MSYS2 at all?

I can't speak for them, but mold can still be used to cross compile Linux binaries on Windows.

I'll go ahead and close, and look into Sold instead since it's open these days

Sold isn't very useful on windows either, it can only create mac binaries

Weird, I thought in original discussions Windows support was a main point.

Damn, so there's nothing out there for Windows binaries?
