From 3e01d1b32e85929b3b9f527cac67c13f0180de19 Mon Sep 17 00:00:00 2001 From: Evgeniy Stepanov Date: Thu, 10 Dec 2015 00:44:42 +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: 255186 --- libcxxabi/cmake/config-ix.cmake | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libcxxabi/cmake/config-ix.cmake b/libcxxabi/cmake/config-ix.cmake index 5405587554b5..ec702e14fedc 100644 --- a/libcxxabi/cmake/config-ix.cmake +++ b/libcxxabi/cmake/config-ix.cmake @@ -39,7 +39,7 @@ check_cxx_compiler_flag(/EHa- LIBCXXABI_HAS_NO_EHA_FLAG) check_cxx_compiler_flag(/GR- LIBCXXABI_HAS_NO_GR_FLAG) # Check libraries -check_library_exists(c printf "" LIBCXXABI_HAS_C_LIB) +check_library_exists(c fopen "" LIBCXXABI_HAS_C_LIB) check_library_exists(dl dladdr "" LIBCXXABI_HAS_DL_LIB) check_library_exists(pthread pthread_once "" LIBCXXABI_HAS_PTHREAD_LIB) check_library_exists(gcc_eh _Unwind_GetRegionStart "" LIBCXXABI_HAS_GCC_EH_LIB)
