Prebuilt LLVM folder not existing anymore #102

Open locadani opened 1 year ago

locadani commented 1 year ago

I am experiencing some problems running the example program and after some time I think I figured out why. I also saw similar issues that might be solved after solving this problem. The folder pointed to by this variable doesn't exists. https://github.com/Rust-GPU/Rust-CUDA/blob/8a6cb734d21d5582052fa5b38089d1aa0f4d582f/crates/rustc_codegen_nvvm/build.rs#L13 Any ideas on how to fix this?

Did you solve the problem? I get the following error

  --- stderr
  thread 'main' panicked at 'Unsupported target with no matching prebuilt LLVM: `x86_64-unknown-linux-gnu`, install LLVM and set LLVM_CONFIG', crates/rustc_codegen_nvvm/build.rs:58:14

No unfortunately, but I did some steps forward. You need to download the prebuilt llvm from here (link), then navigate to downloaded file and make it executable, finally set that as env variable LLVM_CONFIG. Doing this i get some linking problems: /usr/bin/ld: cannot find -lz: No such file or directory /usr/bin/ld: cannot find -ltinfo: No such file or directory collect2: error: ld returned 1 exit status

I solved them running sudo apt-get install libtinfo-dev sudo apt-get install zlib1g-dev sudo apt-get install libxml2-dev But now I have other errors from the cuda/cpu/add crate, that I am trying to solve
