Error when running `bazel run @hedron_compile_commands//:refresh_all` #228

Open rohansatapathy opened 1 month ago

rohansatapathy commented 1 month ago

I'm trying to get clangd to recognize my Bazel dependencies, and I got an error when using this tool. I think the issue might be related to the fact that one of my dependencies Boost.Asio is header-only, so there's no .cpp file to compile it with, but I'm not 100% sure. I'm on macOS Sonoma 14.0, using clang, clangd, LLVM, and Bazelisk installed through Homebrew.

>>> Automatically added //external workspace link:
    This link makes it easy for you--and for build tooling--to see the external dependencies you bring in. It also makes your source tree have the same directory structure as the build sandbox.
    It's a win/win: It's easier for you to browse the code you use, and it eliminates whole categories of edge cases for build tooling.
>>> Analyzing commands used in @//...
WARNING: Build options --features and --host_features have changed, discarding analysis cache (this can be expensive, see https://bazel.build/advanced/performance/iteration-speed).
>>> A source file you compile doesn't (yet) exist: bazel-out/darwin_arm64-fastbuild/bin/external/boost.asio~/boost.asio.src.cpp
    It's probably a generated file, and you haven't yet run a build to generate it.
    That's OK; your code doesn't even have to compile for this tool to work.
    If you can, though, you might want to run a build of your code with --keep_going.
        That way everything possible is generated, browsable and indexed for autocomplete.
    However, if you have *already* built your code, and generated the missing file...
        Please make sure you're supplying this tool with the same flags you use to build.
        You can either use a refresh_compile_commands rule or the special -- syntax. Please see the README.
        [Supplying flags normally won't work. That just causes this tool to be built with those flags.]
    Continuing gracefully...

+1 to this. I encountered the same issue building against @boost.property_tree.

This looks like #199. You can use #219 for a fix while waiting for it to be merged
