> For 15.0.0, it seems libcxx moved to using `__attribute__((using_if_exists))` in order to enable or disable features. See [this commit on LLVM](https://github.com/llvm/llvm-project/commit/a9c9183ca42629fa83cdda297d1d30c7bc1d7c91). As far as I can tell, there is no support for this yet in GCC. I found an open [bug report](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105584), and didn't make any attempts on the upgrade after that. But I think it doesn't matter whether the compiler support using_if_exists since we can implement the lack of c standard library functions which are required by libcxx. -- This is an automated message from the Apache Git Service.
