 Randy Eckenrode | A change was made to fix clang foo.cpp that broke clang-scan-deps, which CMake uses for module support. | 11:33:50 |
| Randy Eckenrode | It had to be ported to the clang-tools wrapper, which would have gone to master if not for the large number of Linux rebuilds it caused. | 11:34:43 |
 megmug | Aha - could this possibly affect non-module projects as well then? Because I am still getting errors despite removing all the modules. clang-scan-deps fails to find some stuff (on macos). | 11:37:28 |
| Randy Eckenrode | If it uses clang-scan-deps, it will be broken. | 11:39:02 |
| Randy Eckenrode | Also clangd. | 11:39:10 |
| Randy Eckenrode | You may be able to work around it by setting env.NIX_CFLAGS_COMPILE to -isystem ${stdenv.cc.libcxx}. | 11:42:42 |

| megmug | Hm, or just build the nix-shell on a different version maybe? Is the change already on master branch? Or can i go back far enough to get a version that didn't have the problem? | 11:44:38 |
| Randy Eckenrode | It’s on staging. It won’t make it to master until mid-December probably. | 11:47:04 |
| Randy Eckenrode | If you use staging, you’ll have to do a stdenv bootstrap and build everything from source. | 11:47:43 |
| megmug | Do I understand correctly that the breaking change was merged on oct 9? Could it be circumvented by going back further than that? | 11:52:20 |
| megmug | On the other hand, building everything from source might not be that bad as long as it's automatic | 11:53:09 |
| Randy Eckenrode | That should also work. | 11:56:55 |
| Randy Eckenrode | It is. It just takes a while. | 11:57:18 |
