No source files found in compile args error #199

davidzchen · 2024-06-13T10:17:17Z

I recently started getting a No source files found in compile args error while running refresh_compile_commands. The error message told me to file an issue for this.

ehuang3 · 2024-06-16T18:04:14Z

I also have this issue. The logic in _get_files(compile_action) does not seem to support a header only compile command. There are no source files because the command is attempting to precompile a header file.

This patch works for me.

davidzchen · 2024-06-16T20:04:17Z

That's odd. I had cc_library targets that only had headers in the past, and the tool ran just fine. Something caused this error to come up recently, but I do not know what changed on my system, aside from maybe Bazel getting updated (I am using bazelisk but I don't have Bazel pinned to a specific version in my repo).

davidzchen · 2024-06-16T20:08:46Z

In any case, this patched worked for me as well. @ehuang3 can you open a PR?

tolikzinovyev · 2024-06-27T15:11:25Z

I started having the same problem in my project. The error also triggers on abseil's header file. I created a small repository so that reproducing is easier. https://github.com/tolikzinovyev/hedron-fail

Hey guys--I'm seeing this and will engage with it shortly, aiming for this weekend. Sorry to be only getting to this now; I've been underwater with other things.

Seems like bazel added a new type of header-only compile action, when formerly they only issued them for source files. I think the first step is to understand what's going on in those actions to make sure there aren't other problems and figure out if there's another way to distinguish them (in case the problem happens also with, e.g. c (not c++) headers, breaking the solution above).

Awesome to have a minimal reproduction case and know the Bazel version that broke it--thanks guys.

If anyone is willing to help in the meantime, I think the next steps would be

Try to dig up the context behind this Bazel change.
Make sure it's still happening in Bazel rolling, if we can't find that context.
Look at the aquery output for those actions to try to understand them better.

rockwotj · 2024-08-01T14:57:57Z

I've also confirmed this still happens in Bazel rolling at least for abseil in my repo

Had to downgrade Bazel to 7.1.2 because it was crashing when building abseil. See issue: hedronvision/bazel-compile-commands-extractor#199

helly25 · 2024-08-18T17:54:30Z

I ran into the same issue on one of my repos. And got it working with #209

The problem is that the source file a header (.h) cannot be found as it is not in the list of source files. There is a PR out that addresses the exact combination: #205

That one also adds support for .h.processed as a target.

However, it does not support all header extension variants ('.hh', '.hpp', '.hxx' and whatnot). So it might be necessary to adding them all and to only use .processed as additional target extension.

rockwotj · 2024-08-20T02:03:13Z

@fmeum sorry to pull you into this, but I believe that bazelbuild/bazel#22369 caused this (because downgrading to Bazel 7.1.0 makes this error go away). Do you know the details of the purpose of the .processed headers are for? Since they are new in 7.2.0, I presume it's safe for a compilation database to just skip adding compilation commands for clangd for these .processed headers. Thanks!

fmeum · 2024-08-20T07:13:15Z

The .processed file is just a synthetic output file that's always empty: Bazel can't run actions that produce no outputs, so the way we get it to run on headers is to wrap the compiler with a script that produces this empty file.

While the file itself isn't interesting, the action very well could be. For a header-only library with no consumers, it does provide flags with which the library at least parses correctly. That makes an approach such as #209 look reasonable to me.

I am working on adding a new action that supports C headers (via -xc-header), but this hasn't been merged yet.

helly25 · 2024-08-20T09:16:20Z

Thanks for confirming @fmeum. The header only libraries get their own entries this way. Which imo is a clear improvement.

I have this issue if I use boost.move:

cc_library(
    name = "lib",

    ],
    includes = ["include"],
    visibility = ["//visibility:public"],
    deps = [
        "@boost.move",
    ],
)
