Subject: shmctl not found when compiling compiler-rt
Date: Tue, 13 Feb 2018 15:34:34 +0200 [thread overview]
Message-ID: <220501518528874@web47o.yandex.ru> (raw)
Hi!
I'm trying to compile compiler-rt with musl and it used to be fine, but I can't succeed with recent versions of compiler-rt.
The compilation fails because of the lack of real_shmctl while musl clearly has shmctl: http://git.musl-libc.org/cgit/musl/tree/src/ipc/shmctl.c
Here is the complete output:
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);

Can you please help me to understand why is it not compiling and how to make it compile again?
To compile without glibc on linux using this patch:
