我添加了 AddressSanitizer 标志如下:
I've added AddressSanitizer flag as follow:
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fsanitize=address")
使用 Unix Makefiles
时,一切构建和运行良好.
Everything builds and runs fine when using Unix Makefiles
.
问题是在生成Xcode项目的时候,它只是不想链接,因为它找不到ASan库.
The problem comes when generating the Xcode project, it just doesn't want to link because it cannot find the ASan library.
我已经找到了两个解决方案,但决定不使用它们,因为它们无法仅使用 CMake 实现自动化:
I already found two solutions, but decided not to use them because they cannot be automated using just CMake:
-Wl,-undefined,dynamic_lookup
添加到链接标志,因此它跳过链接到动态库.libclang_rt.asan_osx_dynamic.dylib
链接.-Wl,-undefined,dynamic_lookup
to the linked flags, so it skips linking to dynamic libraries. libclang_rt.asan_osx_dynamic.dylib
directly.那么这两种解决方案有什么问题?
So what's the problem with these two solutions?
libclang_rt.asan_osx_dynamic.dylib
的 DYLD_INSERT_LIBRARIES
环境变量.此外,作为另一种解决方案,我尝试从 Xcode 目标方案启用 Address Sanitizer 标志,但有趣的是它没有检测到我添加的问题,所以我没有将其列为解决方案,因为它没有通过我的测试.
Additionally as another solution, I tried enabling Address Sanitizer flag from the Xcode target scheme but interestingly it didn't detect the issues I added, so I didn't list this as a solution because it failed my test.
任何帮助将不胜感激.
您也需要向链接器提供标志.我是这样做的:
You need to provide the flag(s) to the linker too. I'm doing it like this:
set (CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -fno-omit-frame-pointer -fsanitize=address")
set (CMAKE_LINKER_FLAGS_DEBUG "${CMAKE_LINKER_FLAGS_DEBUG} -fno-omit-frame-pointer -fsanitize=address")
