'could not load cache' when building llvm-mctoll #137

Closed Brubbish closed 3 years ago

Brubbish commented 3 years ago

I am new in llvm and cmake, so the issue might a bit shallow I've already processed 4 steps in 'Building as part of the LLVM tree' in README. I stuck in step 5 when I use cmake --build ../../mctoll-build/ -- llvm-mctoll and it occurred an Error: could not load cache. image

my OS is Ubuntu20.04

Thanks for your interest in the project.

A couple of potential things to verify:

  1. Check disk space availability.
  2. Ensure your source directory structure is as expected i.e., llvm-mctoll directory is in llvm-project/llvm/tools directory.
  3. Follow the steps in README.md verbatim, if you are new to LLVM ecosystem.

@bharadwajy Thanks a lot, I found I missed the step to put llvm-mctoll dir in the right directory.

Also, if someone has a problem cloning llvm-project in Github due to GFW like me, tuna's llvm-project mirror is a smart choice. If it occurs to have errors while executing cmake --build ./ -- llvm-mctoll, it is maybe because of your low ram.
