[lldb-dev] Conditionally adding sources to the build

[Dmitry Mikulin via lldb-dev]

I have a slightly unrelated question: is there an easy way to cross-build, say, an ARM lldb, and run native tests on an ARM board same as what check-lldb does? The lldb test page only talks about running remote tests. No info on cross testing.

Thanks!

I am glad to see freebsd is making progress on this front. If you need any help with understanding how lldb-server works, feel free to shoot me a question.

Thanks for the suggestions.
I’m working on native support for FreeBSD lldb-server, and wanted to have an option to build it both ways until it’s stable enough to replace current implementation. I’ll have it in a separate directory.

The way we have done this with Linux native register contexts was to notionally leave the files in the build, but completely #ifdef out their contents (see NativeRegisterConextLinux_arm.cpp).
It's not very nice, but I think it's better than having six subfolders, each with a single cpp file. If you'll need to group more than one file this way, then maybe a subfolder would make more sense though.

Unfortunately you will need to separate them at the directory levels.

Hi,

I’m trying to conditionally add source files to the lldb build based on a cmake configure time variable. I get the following type of errors for all sources not included in the build:

CMake Error at cmake/modules/LLVMProcessSources.cmake:83 (message):
  Found unknown source file
  /homes/dmitrym/buildspace/llvm-tot/llvm/tools/lldb/source/Plugins/Process/FreeBSD/FreeBSDThread.cpp

  Please update
  /homes/dmitrym/buildspace/llvm-tot/llvm/tools/lldb/source/Plugins/Process/FreeBSD/CMakeLists.txt

Is there a way to work around/fix it or do I need to separate the files at the directory level?

Thanks.
Dmitry.
