Ubuntu20.04下GCC编译器使用asan须知

背景

只在CFLAGS和CXXFLAGS加-fsanitize=address是不够的，会编译失败，报出一堆undefined reference to __asan_report_XXX这样的报错，例如
undefined reference to __asan_report_load1
各种各种......

解决方法

在Cmake里就是

ADD_DEFINITIONS("-fPIC -Wall -fpermissive -fsanitize=address ")
TARGET_LINK_LIBRARIES(...... rt pthread dl -fsanitize=address -Wl,-rpath,'$ORIGIN'/libs)
