Linking with LLD fails but only in 32-bit (due to space in path)

Boscop · October 23, 2020, 12:26am

The 32-bit build of my DLL fails to build with nightly-2020-10-19 when linking with LLD.
It was building fine with nightly-2020-04-12, but I'm not sure if I was using LLD back then already.
LLD seems to have problems with a space in my rustup path, but it used to work before, also building for 32-bit!
My rustup folder is D:\Program Files\.multirust, but it tries to use Files\.multirust.
How can I get it to work?
Btw, this DLL builds fine in 64-bit with this nightly!

  = note: lld-link: error: could not open 'Files\.multirust\toolchains\nightly-2

That sounds like the following issue, but it's supposed to be fixed now...

Oh, but that fix was only for wasm. It sounds like we'll need that argument in more places...
