59 Patches Allow Finally Building Glibc With LLVM's Clang Compiler

Written by Michael Larabel in GNU on 28 October 2025 at 05:46 AM EDT. 13 Comments
Linaro engineer Adhemerval Zanella recently sent out a set of 59 patches to allow building the GNU C Library "glibc" with the LLVM Clang compiler as an alternative to GCC.

The patches are focused on being able to use Clang to build the GNU C Library for x86_64 Linux and AArch64 Linux systems. Clang 18 and newer in turn can then build a working glibc. One caveat though is that the GCC runtime support is still needed with further work needed to adapt to Clang's compiler-rt runtime library.

Those interested in building the GNU C Library with LLVM Clang can find the patches under review on the libc-alpha mailing list.
