Problems building on Arch Linux - undefined reference to `clang_CXXMethod_isDeleted' etc.

[expenses]

Hi! I started looking into babble to build the rust bindings for USD but I ran into an error during the linking step of cargo test. Here's the output with the long compilation commands edited down:

warning: `bbl-write` (lib) generated 1 warning
error: linking with `cc` failed: exit status: 1

error: could not compile `bbl-write` due to previous error

This happens regardless of what I set the CLANG_EXECUTABLE, LLVM_CONFIG_PATH and LLVM_ROOT environment variables to. I do have Clang and LLVM 15 installed, but downloading and setting the environment variables to the Clang/LLVM 14 binaries didn't help. Perhaps I need to set something to point to the Clang 14 headers instead?

[scott-wilson]

Hey, unfortunately I can't help you with this issue, but tagging @anderslanglands for help. However, have you spoken with @luke-titley? He's working on USD bindings as well, and right now he's using cpp to do the bindings.

I noticed that babble actually requires Clang 16:

babble/bbl-clang/Cargo.toml

Lines 20 to 23 in 918c79d

	[features]
	clang_16 = ["clang-sys/clang_16_0"]
	clang_13 = ["clang-sys/clang_13_0"]
	default = ["clang_16"]

so I'm currently compiling the llvm-git (it's taking a while!) to try it out.

However, have you spoken with @luke-titley? He's working on USD bindings as well, and right now he's using cpp to do the bindings.

I have not. If you mean https://github.com/vfx-rs/usd-bind then I avoided that because I had trouble with building cppmm and vfx-rs/usd-bind#18 suggested that babble is a successor to cppmm anyway.

[scott-wilson]

Yeah, I think the project description might need to be updated. Right now that's using the cpp crate, and may migrate over to Babble later. Either way, I highly suggest chatting with Luke, since he is pretty far in development last I checked.

I tried compiling with the version of llvm that I compiled but I still had no luck. The final environment variables I ended up trying were CLANG_EXECUTABLE=/home/projects/usd-rs/llvm-16/bin/clang LLVM_CONFIG_PATH=/home/ashley/projects/usd-rs/llvm-16/bin/llvm-config LIBCLANG_PATH=/home/ashley/projects/usd-rs/llvm-16/lib/ cargo test
