Have you installed llvm, too? pacman -S llvm.

[DaanA32]

I have it installed...
I'm not sure why it would try to link to missing libs. I've tried setting the clang-sys and bindgen to feature runtime, but that doesn't seem to work either.

I found https://bugs.archlinux.org/task/66283, so it seems we need to link to only libclang-cpp.so instead of all of the individual libclang*.sos. I think this happend in https://gitlab.archlinux.org/archlinux/packaging/packages/clang/-/commit/aaab40456297f626dfd60ad6632559c65d86bf6b. I'm not sure how package versions work on Arch; can you install an older version of the clang package, or how can we detect which clang package version it is so we can link to libclang-cpp.so instead?

[DaanA32]

Hi kkysen,

I'll try finding / installing a version which does include the shared libs.

The list of all clang.*.so files from the default clang version installed on arch (x86_64) is:
https://archlinux.org/packages/extra/x86_64/clang/files/

$ pacman -Ql clang | grep '\.so'
clang /usr/lib/libclang-cpp.so
clang /usr/lib/libclang-cpp.so.16
clang /usr/lib/libclang.so
clang /usr/lib/libclang.so.16
clang /usr/lib/libclang.so.16.0.6

I tried installing clang10, but that also is compiled with the same options.
I've not found an quick to install version with the BUILD_SHARED_LIBS=ON yet.

I think providing a ENV or feature flag to know what to compile against should be sufficient.

Hi kkysen,

I've managed to fix building by doing the following:

export LLVM_LIB_DIR=/usr/lib

It looks like arch linux installs it to /usr/lib instead of /usr/lib/llvmXX
I think build.rs from c2rust-ast-export does not search /usr/lib.

I've managed to fix building by doing the following:

export LLVM_LIB_DIR=/usr/lib

It looks like arch linux installs it to /usr/lib instead of /usr/lib/llvmXX I think build.rs from c2rust-ast-export does not search /usr/lib.

If we just need to add /usr/lib/ to build.rs's search path on top of /usr/lib/llvm*, we should be able to do that. I can open a PR for that. Thanks for figuring that out!
