Like it says in #357, this is a packaging issue. If you follow the instructions in the README to build LLVM from source you will not see this.

ligurio commented 3 weeks ago

I've followed instructions in a README.md and built LLVM 13 from source. Building terra with LLVM 13 produces a huge number of linkage errors:

Then I've followed instructions in a README.md and built LLVM 18 (llvm-18.1.3) from source. Instruction in a README missed several steps important for successful LLVM build. Building terra with LLVM 18 is failed on a linkage due to error:

According to advice in ^1 I've rebuilt terra with CXXFLAGS=-fno-rtti and terra builds successfully. But on start:

: CommandLine Error: Option 'o' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Aborted (core dumped)

Please help.

I don't have Ubuntu 22.04 personally, so I am using Docker to build. But this should give you a basis for debugging—if it works here and not on your machine, maybe you have some difference in your system configuration that is causing problems.

Note that the LLVM 18 source build is slightly different because LLVM changed the source distribution layout, but that other than the combined tarball and one additional flag -DLLVM_ENABLE_PROJECTS='clang', everything should be basically the same.

One other thing I'll mention: link errors like what you show me are relatively unusual. I actually cannot think of the last time I've seen something like that. I wonder if it's possible that you're not actually using your source builds of LLVM. If you accidentally mixed builds or used the wrong one, that would be a classic way to get the errors you indicated.

Configuration for Ubuntu 22.04 and LLVM 13

Many thanks! Finally, I can build it with LLVM 18.
