From 1e89f4f2c56e6698d703a26f1281e3e57acecc50 Mon Sep 17 00:00:00 2001 From: redfish Date: Fri, 8 Jul 2016 22:34:43 -0400 Subject: cmake: do not ignore dangerous warnings with -Wno-error Shorten the list of warnings that are reported, but which are forced to NOT generate an error, via -Wno-error. Unwhitelist these: strict-aliasing, sign-compare, type-limits For example, ignoring strict-aliasing warning caused lots of wasted time diagnosing Issue #847. --- CMakeLists.txt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 6b9c81895..c250b7ca4 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -314,7 +314,7 @@ else() set(ARCH_FLAG "-march=${ARCH}") endif() endif() - set(WARNINGS "-Wall -Wextra -Wpointer-arith -Wundef -Wvla -Wwrite-strings -Wno-error=extra -Wno-error=deprecated-declarations -Wno-error=sign-compare -Wno-error=strict-aliasing -Wno-error=type-limits -Wno-unused-parameter -Wno-error=unused-variable -Wno-error=undef -Wno-error=uninitialized") + set(WARNINGS "-Wall -Wextra -Wpointer-arith -Wundef -Wvla -Wwrite-strings -Wno-error=extra -Wno-error=deprecated-declarations -Wno-unused-parameter -Wno-error=unused-variable -Wno-error=undef -Wno-error=uninitialized") if(CMAKE_C_COMPILER_ID STREQUAL "Clang") set(WARNINGS "${WARNINGS} -Wno-deprecated-register") endif() -- cgit v1.2.3
