From 858f1f7f8bc28f3652d60058531f7a1ceb028f5b Mon Sep 17 00:00:00 2001 From: Pino Toscano Date: Mon, 21 Nov 2022 08:13:21 +0000 Subject: [PATCH] On Hurd, do not look for functions unimplemented in libc Last-Update: 2022-02-22 Forwarded: not-needed The check_function_exists() function of cmake does not keep into account the defines that glibc provides for the stubs (i.e. unimplemented functions that always return ENOSYS), so some functions are detected as available. Unfortunately, due to --fatal-warnings for the linker, linking will fail. Hence, do not attempt to look for functions that are currently unimplemented on GNU/Hurd's libc.
