[CMake] cross compiling lldb-server

Hi,

I’m looking at cross compiling lldb-server for a Linux target. My use case only needs lldb-server cross-compiled for the target. I’m finding it’s expecting a cross-compiled clang.

It would be great to have a build option to support cross-compiling only lldb-server.

The other scenario is an architecture specific lldb-server. Say I want AArch64, and the only thing to run on the target is AArch64. I would never need support for mip64, etc. This would also minimize the size.

Maybe I’m missing something?

Unfortunately, the way the dependencies in lldb are laid out right now, it's impossible to compile lldb-server without a matching clang, even though the latter will not be used in any meaningful way. Changing that is one of my goals, but it's not something that's going to happen soon.

As for the architecture part of the question, you should be able to achieve something like that by setting the LLVM_TARGETS_TO_BUILD=AArch64 cmake variable.

cheers,

Ok, thanks for the info.
