| Package | “default-libcxx” Flag Description |
|---|---|
| llvm-core/clang-common | Use libc++ instead of libstdc++ as the default stdlib for clang. Beware: this breaks ABI, producing binaries incompatible with those built with GCC or Clang using libstdc++. Do not set unless you know what you're doing. |
| llvm-runtimes/clang-runtime | Use libc++ instead of libstdc++ as the default stdlib for clang |
| llvm-runtimes/clang-stdlib-config | Use libc++ instead of libstdc++ as the default stdlib for clang |
