From 2abfe726b2a1896dbe3966e26689752b54ab0617 Mon Sep 17 00:00:00 2001 From: Evgeniy Stepanov Date: Thu, 10 Dec 2015 00:45:18 +0000 Subject: [PATCH] Replace cmake check for printf with a check for fopen. Printf is a builtin, and the check fails with -Werror because of a clang warning about an incompatible redeclaration. llvm-svn: 255187 --- libcxx/cmake/config-ix.cmake | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libcxx/cmake/config-ix.cmake b/libcxx/cmake/config-ix.cmake index 3b747b2e4116..c05597ea73dd 100644 --- a/libcxx/cmake/config-ix.cmake +++ b/libcxx/cmake/config-ix.cmake @@ -13,7 +13,7 @@ check_cxx_compiler_flag(/GR- LIBCXX_HAS_NO_GR_FLAG) # Check libraries check_library_exists(pthread pthread_create "" LIBCXX_HAS_PTHREAD_LIB) -check_library_exists(c printf "" LIBCXX_HAS_C_LIB) +check_library_exists(c fopen "" LIBCXX_HAS_C_LIB) check_library_exists(m ccos "" LIBCXX_HAS_M_LIB) check_library_exists(rt clock_gettime "" LIBCXX_HAS_RT_LIB) check_library_exists(gcc_s __gcc_personality_v0 "" LIBCXX_HAS_GCC_S_LIB)
