So I am trying to build carbon-lang i have done everything, installed clang/llvm it works fine but when I run the command bazel run //explorer -- ./explorer/testdata/print/format_only.carbon
it gives me this error I have googled but cannot find the solution to this error:
[bret@archxbret carbon-lang]$ bazel run //explorer -- ./explorer/testdata/print/format_only.carbon

I am using arch Linux any help is appreciated I have tried adding llvm to path but it doesn't seem to work.
the llvm is in /usr/include/llvm but when I add it to my .bashrc and source it it shows up in when I echo $PATH but when I run the command which llvm it shows that no llvm found in the current added to PATH directories unlike when I run which clang it shows that it is found in /usr/bin
but the command llvm-config --version works so I am not sure if it means that is already added to PATH or not.
I am really lost here any help is appreciated.
apologies in advance if I made an obvious mistake.
So after rigorously searching for a solution to this error it turns out that carbon has issues with system installed versions of clang and llvm and for now if you want carbon-lang to work you have to install llvm with homebrew.
