From 3d8b5dde879c6e024548118914da5bfcbd5170a7 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 25 Oct 2022 11:07:59 -0300 Subject: nptl: Fix pthread_create.c build with clang clang complains that libc_hidden_data_def (__nptl_threads_events) creates an invalid alias: pthread_create.c:50:1: error: alias must point to a defined variable or function libc_hidden_data_def (__nptl_threads_events) ^ ../include/libc-symbols.h:621:37: note: expanded from macro 'libc_hidden_data_def' It seems that clang requires that a proper prototype is defined prior the hidden alias creation.
