Seems that Clang is unable to find stdbool.h, which should be part
of the C standard library since C99. This is strange, it seems that
your Clang installation is not complete. See this link for
instructions.  This requirement should be removed when the
requirement on rust-bindgen is removed.

It's a new machine and I don't have clang installed at all.

$ rpm -qa | grep clang
clang15-resource-filesystem-15.0.7-4.fc38.x86_64
clang15-libs-15.0.7-4.fc38.x86_64
clang-resource-filesystem-16.0.5-4.fc39.x86_64
clang-libs-16.0.5-4.fc39.x86_64
$ rpm -qa | grep llvm
llvm15-libs-15.0.7-4.fc38.x86_64
llvm-libs-16.0.5-2.fc39.x86_64

I have never used rpm, but if you are using Fedora, the following command should be enough:

    dnf install clang-devel

According to this link.

I seem to remember in some project we had a configure-time test to
check if rust/cargo was working, compiling a simple test program, but
I can't find that right now.

Rich.

That was actually this project. I removed it because we both thought it was unnecessary. And I actually think it wouldn't catch this problem anyway because this is directly related to rust-bindgen.

Best regards,
