possible alternative: use llvm-config to set these include paths

example env's on nixos:

$ echo $LIBCXX_INCLUDE_DIR
/nix/store/hzlq2g5man7zi3xr9165gz39ccxxray2-libcxx-11.1.0-dev/include

$ echo $GLIBC_INCLUDE_DIR
/nix/store/vccvfa5bjb9dv4x6zq5gjf1yp58y4brg-glibc-2.33-108-dev/include

$ echo $LIBC_INCLUDE_DIR
/nix/store/dxdajaz6l6mzm3iil34qs3rz9cm6gpjz-clang-11.1.0-lib/lib/clang/11.1.0/include

strangely, it works with nix-shell but fails with nix-build (debugging this is on my todo list ...)

@milahu, where would LIBCXX_INCLUDE_DIR, GLIBC_INCLUDE_DIR, and LIBC_INCLUDE_DIR be set? They aren't normally set outside of nix os. Getting these from llvm-config would be better, but I don't think llvm-config has these paths. llvm-config --includedir is for the headers for llvm/clang's own headers, not libc's and libcxx's.

If you make these environment variables optional overrides in c2rust-ast-exporter/build.rs, I thought that would work fine.

milahu · 2022-06-29T21:19:43Z

i guess this is mostly a nix problem (multi prefix filesystem)

if c2rust could expose these env-vars
this would make the nix side like 1% simpler (less patching)

in nix there is also clangStdenv.mkDerivation instead of the default stdenv.mkDerivation
where all these include paths should be set by default

see https://nixos.wiki/wiki/Using_Clang_instead_of_GCC

its just a challenge to combine rustPlatform.buildRustPackage and clangStdenv.mkDerivation
maybe something like

rustPlatform.buildRustPackage {
  buildInputs = [
    clangStdenv.cc
  ];
}

~~I'm getting this error building on Ubuntu 22.04 with the nightly toolchain as well.~~

Seems to be rectified after double checking my libstdc++ install, might be something to mention in the readme.

64kramsystem · 2022-11-11T18:45:43Z

For reference, I was experiencing this on my system(s), both Ubuntu 22.04.

The solution has been to install the package libstdc++-12-dev. @kkysen I think this should be added to the README; I'd add this myself, but the details confuse me, specifically, why v12 is required on Ubuntu 22.04, while on Ubuntu 20.04, older versions were fine 😬

abentley · 2023-05-27T15:46:26Z

I can confirm that installing libstdc++-12-dev stopped the compile failures on Ubuntu 22.04, but this seems more like a workaround than a true fix. The compile failures were happening with libstdc++-11-dev, which also provides <algorithm> (and std::fill_n, which seems to be one of the things used by ExportResult.cpp). So it really seems like compiling with libstdc++11-dev ought to work.

richardhapb · 2024-12-11T23:39:31Z

In Mac you need install gcc.

brew install gcc

64kramsystem · 2024-12-12T09:52:04Z

Just tested on 24.04, and there's a similar workaround - libstdc++-14-dev is this time required (with v10/12/13 all installed, build fails).

richardhapb · 2024-12-12T15:37:21Z

Try this:

brew install llvm
export CC=$(brew --prefix llvm)/bin/clang
export CXX=$(brew --prefix llvm)/bin/clang++

And try again the package installation.

if it works, append those exports to .zshrc file for avoid the error in the future.
