Warning spam when there are completely unrelated JSON files in build folder

[anthonyalayo]

Hey there,

Is there support for Clang 14/15/16? I noticed your previous history of adding support for new Clang versions, and I'm noticing a lot of errors and a missing trace.json at the top level.

[aras-p]

Can you attach example of json file, and what kind of errors you get?

[anthonyalayo]

@aras-p thanks for the quick response, I'll be back at my computer in an hour and I'll get a dump for you.

[anthonyalayo]

@aras-p, came back home and tried a few things, and I realized this happens even with Clang 13.

❯ clang --version
Homebrew clang version 13.0.1
Target: arm64-apple-darwin22.3.0
Thread model: posix
InstalledDir: /opt/homebrew/bin

❯ ninja --version
1.11.1

❯ cmake --version
cmake version 3.27.7

I added this to my library target (before the executable):

target_compile_options(${PROJECT_LIB_NAME} PRIVATE -ftime-trace)

Then I ran the following:

ClangBuildAnalyzer --all build output.bin

And I get this:

  done in 3.6s. Run 'ClangBuildAnalyzer --analyze output.bin' to analyze it.

Am I perhaps doing something wrong? I noticed there is no top level JSON trace file.

[anthonyalayo]

Any idea what causes those @aras-p ?

[aras-p]

I just tested locally with clang 14 and clang 16, and everything seems to work as expected. Hard to say what goes wrong without seeing at least some of the json files that would be produced next to object files under your build folder.

[e4lam]

For the record, I get these too.

[aras-p]

And again, without knowing what is in these json files, it's hard to say what's going on

[e4lam]

So I updated to the latest code. It's because it's processing random json files part of my project that are not from clang :( Is there a way to specify a pattern to match when it does things recursively? I think something like *.C.json would work well for me.

[anthonyalayo]

nice find @e4lam , i think thats my problem too

[alecazam]

There are a whole bunch of json files, that Xcode dumps out to the build directories. clang is on all platforms now, so you didn't really state what platform you were building on.
