LLVM >= 14.0 is required to build nightly #21

Closed zacknewman closed 1 year ago

zacknewman commented 1 year ago

I realize that building nightly is only supported on -current; however I believe the error I get on -stable would be relevant on -current too since LLVM in -current is 13.0.0p7. I am a little surprised that LLVM hasn't been updated since 16.0.0 was released back in March. I am sure there are reasons for not updating LLVM, but this kind of thing may become more common as LLVM progresses. Regardless, here is the last portion of the build I get:

you need to build it with the embedded llvm version (or an external llvm>=14 build). I don't have put it by default in build.sh for now.

it could be configured via ~/.build_rust.conf:

$ echo llvm_config=no >> ${HOME}/.build_rust.conf`

you are strongly adviced to use ccache to avoid painful llvm rebuild.

Nice, that fixed that error.

Indeed. Fortunately it is on by default.
