Trying to build compiler_rt for use on Linux with musl libc, but the build fails with the following:
/src/llvm/projects/compiler-rt/lib/msan/msan_interceptors.cc:1446:15: error: no member named 'real_shmctl' in namespace '__interception'; did you mean 'real_ioctl'?
int res = REAL(shmctl)(shmid, shmctl_ipc_stat, &ds);

Could you please suggest why don't I have real shmctl and how do I get this function?
