From 8e0799ded6b0dc6f1d35c605ef823b093622ab4c Mon Sep 17 00:00:00 2001 From: Omair Majid Date: Tue, 18 Feb 2020 13:27:24 -0500 Subject: Fix build on systems with glibc >= 2.30 (#28012) On newer systems with glibc 2.30, the compiler emits a warning: In file included from coreclr/src/pal/src/misc/sysinfo.cpp:32: /usr/include/sys/sysctl.h:21:2: error: "The header is deprecated and will be removed." [-Werror,-W#warnings] #warning "The header is deprecated and will be removed." ^ The glibc 2.30 release notes cover this at https://sourceware.org/ml/libc-alpha/2019-08/msg00029.html: * The Linux-specific header and the sysctl function have been deprecated and will be removed from a future version of glibc. Application should directly access /proc instead. For obtaining random bits, the getentropy function can be used. To keep coreclr release/3.1 building, disable treating the #warning as an error. Clang and GCC have separate flags to turn this error off. --- configurecompiler.cmake | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/configurecompiler.cmake b/configurecompiler.cmake index cc77ed082f..5d5925c8bf 100644 --- a/configurecompiler.cmake +++ b/configurecompiler.cmake @@ -521,11 +521,15 @@ if (CLR_CMAKE_PLATFORM_UNIX) # to a struct or a class that has virtual members or a base class.
