Linker error on Windows with lld-link: relocation against symbol in discarded section

[danakj]

it actually ends up crashing lld-link, but the errors come first, so I think it's also doing something wrong.

I tried with and without used_linker and get the same thing either way, whereas used_linker fixed lld on other platforms.

The GTESTS here is the distributed_slice, in the rust_gtest_interop crate.

This should be reproducible on Windows outside of Chromium with --target=x86_64-pc-windows-msvc -Clinker=clang-cl -Clink-arg=-fuse-ld=lld.

[danakj]

I can reproduce with cargo test on Windows with the following steps:

1. Download lld-link.exe. You can get it from Chromium here.

From the linkme repository root:

1. tar xf path..to..downloaded\clang-llvmorg-17-init-16420-g0c545a44-5.tgz bin/lld-link.exe

   • You will now have a bin/lld-link.exe

2. Create .cargo/config.toml that contains

[target.x86_64-pc-windows-msvc]
rustflags = ["-Clinker=path..to../linkme/bin/lld-link"]

I used:

[target.x86_64-pc-windows-msvc]
rustflags = ["-Clinker=C:/src/linkme/bin/lld-link"]

3. Run cargo test

used_linker

Testing with used_linker gets the same result. But given that used_linker is needed to resolve linking with lld on other platforms, it would be fine if this is needed for whatever the fix is.

I tried adding the LINKME_PLEASE symbol on target_os = "windows" into the #windows_section but it did not help. I am a bit out of depth and about to go on vacation so someone else will need to pick this up sorry.

Ran into this issue today! This still happens with current LLD and linkme.

I was able to fix this by adding a public symbol to any crates that I was only using to add to linkme distributed slices:

pub fn please_link_me() {}

...which I then call anywhere in a bin crate:

systems::please_link_me();
editor_systems::please_link_me();
render_systems::please_link_me();
