bbl-translate fails to #include babble when compiled on macOS

[expenses]

I'm trying to build babble on mac (#10 branch). I'm compiling with the homebrew-installed llvm and zig cc as a compiler as it uses its own toolchain and avoids some of the problems I've been having with native/homebrew clang. The full build script is
CC=zig-cc CXX=zig-c++ cmake -S . -B build -G Ninja -DCMAKE_INSTALL_PREFIX=install -DLLVM_DIR=/usr/local/Cellar/llvm/17.0.6_1/lib/cmake/llvm/ && cmake --build build

(zig-cc and zig-c++ are just files installed in ~/.local/bin containing zig c++ $@ etc.).

I'm getting this issue with the tests where bbl-translate is run:

I don't really know what to make of it.

Assuming that babble is indeed in Users/ashley/babble/bbl/include, what happens if you change

#include "babble"

to

#include <babble>

in the smartptr bindfile?

Changing to

#include <babble>

results in a different but similar error message:
/Users/ashley/babble/build/bbl/bbl-translate /Users/ashley/babble/test/stdfunction/bind.cpp -- -std=c++17 -fsyntax-only -fno-spell-checking -I/usr/local/opt /llvm/lib/clang/17/include -I/Users/ashley/babble/bbl/include -I/Users/ashley/babble/test/stdfunction -- stdfunction -o /Users/ashley/babble/build/test/stdfunction

/Users/ashley/babble/test/stdfunction/bind.cpp:1:10: fatal error: cannot open file '/usr/local/opt/llvm/lib/clang/17/include/babble': No such file or directory

    1 | #include <babble>
      |          ^

If I remove the first include from the bbl-translate invocation (-I/usr/local/opt/llvm/lib/clang/17/include) then I get a different error:
/Users/ashley/babble/build/bbl/bbl-translate /Users/ashley/babble/test/stdfunction/bind.cpp -- -std=c++17 -fsyntax-only -fno-spell-checking -I/Users/ashley/babble/bbl/include -I/Users/ashley/babble/test/stdfunction -- stdfunction -o /Users/ashley/babble/build/test/stdfunction

/Users/ashley/babble/bbl/include/babble:4:10: fatal error: cannot open file '/Users/ashley/babble/bbl/include/type_traits': No such file or directory

I get the same error if I just reorder the includes to this:
/Users/ashley/babble/build/bbl/bbl-translate /Users/ashley/babble/test/stdfunction/bind.cpp -- -std=c++17 -fsyntax-only -fno-spell-checking -I/Users/ashley/babble/bbl/include -I/usr/local/opt/llvm/lib/clang/17/include -I/Users/ashley/babble/test/stdfunction -- stdfunction -o /Users/ashley/babble/build/test/stdfunction

It seems like only the first -I flag is being registered for whatever reason.

Actually even with
/Users/ashley/babble/build/bbl/bbl-translate /Users/ashley/babble/test/stdfunction/bind.cpp -- -std=c++17 -fsyntax-only -fno-spell-checking -I/Users/ashley/babble/bbl/include ...
I still get
/Users/ashley/babble/test/stdfunction/bind.cpp:1:10: fatal error: cannot open file '/Users/ashley/babble/test/stdfunction/babble': No such file or directory
so I'm not really sure my hypothesis holds up. Something is definitely funky with how the -I flags are handled though.

[anderslanglands]

The `<type_traits>` error I know the cause and can hopefully provide a fix soon.

Okay great, I've had a bit more success compiling in a nix shell with nix-shell -p llvm libclang and that's the next error to fix.

[anderslanglands]

Just following up on this, the type_traits error should now be fixed
