Trying to build and full toolchain based on 19.x #278

Closed quic-seaswara closed 2 months ago

I am on version Ubuntu 18.04 and trying to use this repository to build a complete toolchain so that I can use the latest LLVM tools for my development needs.

I use this currently in this way below :-

python3.9 build-llvm.py -f -r release/19.x -D LLVM_ENABLE_RUNTIMES:STRING="libunwind;libcxxabi;libcxx" LLVM_CCACHE_BUILD:BOOL=ON LLVM_TOOL_MLIR_BUILD:BOOL=OFF LLVM_ALL_PROJECTS:STRING="bolt;clang;clang-tools-extra;compiler-rt;cross-project-tests;lld;lldb;pstl" -i

the bootstrap build is successful, but the final build fails with errors on libc/mlir/bolt.

Even if I have not enabled libc/mlir the final stage build builds all of them.

How do you use the scripts to build the full toolchain ?

Thanks for all this work

I don't know if it is related but I don't think the :<type> part of the current -D value format of <var_name>:<type>=<val> is strictly necessary. Could you try your same command with the -D values formatted as <var_name>=<val> and see if that fixes it?

Thank you @nathanchance. I was able to finally build using this command line

python3.9 build-llvm.py -f -r release/19.x -D LLVM_ENABLE_RUNTIMES:STRING="libunwind;libcxxabi;libcxx" LLVM_CCACHE_BUILD=ON LLVM_TOOL_MLIR_BUILD=OFF MLIR_INCLUDE_TESTS=OFF LLVM_ENABLE_PROJECTS:STRING="bolt;clang;mlir;clang-tools-extra;compiler-rt;cross-project-tests;lld;lldb;pstl" -i /local/mnt/workspace/seaswara/tc_build/ --no-ccache
