如何在CMake释放模式下启用断言? [英] How to enable assert in CMake Release mode?
问题描述
CMake用于编译一些C ++文件。在代码中有 assert
调用。在CMake的释放模式下禁用这些呼叫。它在发布模式下定义 NDEBUG
。
如果我有兴趣在发布模式> > >
如果启用此功能,你只对自己的代码感兴趣 assert
功能,那么简单的一个解决方案
就是提供自定义断言。例如:
#if(MY_DEBUG)
#define MY_ASSERT
#else
#define MY_ASSERT(A)...忽略A ...
#endif
使用选项
启用/禁用assert:
#CMakeLists.txt
选项(ENABLE_MY_ASSERT打开MY_ASSERT检查关闭)
if(ENABLE_MY_ASSERT)
add_definitions(-DMY_DEBUG = 1)
else b $ b add_definitions(-DMY_DEBUG = 0)
endif()
可以完全控制您的支票,您可以验证一个
组件并忽略其他:
... FOO_DEBUG = 0 BOO_DEBUG = 1 BAR_DEBUG = 0 ...

$ b b
添加自定义 CMAKE_BUILD_TYPE (也请参阅 CMAKE_CONFIGURATION_TYPES ):
cmake_minimum_required(VERSION 2.8.12)
project(foo)
set(CMAKE_CXX_FLAGS_MYREL-O3)
add_library(foo foo.cpp)
输出:
#调试
#... -g ...
#发布
# ... -O3 -DNDEBUG ...
#RelWithDebInfo
#... -O2 -g -DNDEBUG ...
#MyRel
#... -O3 ...
CMake is being used to compile some C++ files. There are assert
calls in the code. These calls are disabled in Release mode of CMake. It defines NDEBUG
in Release mode, I guess.
If I'm interested in having assert in Release mode of CMake, how do I enable it?

If you interested in assert
functionality only in your own code then the simple one solution
is to provide custom assert. For instance:
#if (MY_DEBUG)
# define MY_ASSERT(A) ... checks here ...
#else
# define MY_ASSERT(A) ... ignore A ...
#endif
Use option
to enable/disable assert:
# CMakeLists.txt
option(ENABLE_MY_ASSERT "Turn on MY_ASSERT checks" OFF)
if(ENABLE_MY_ASSERT)
add_definitions(-DMY_DEBUG=1)
else()
add_definitions(-DMY_DEBUG=0)
endif()
In this case you have full control over your checks, you can verify one component and ignore others:
... FOO_DEBUG=0 BOO_DEBUG=1 BAR_DEBUG=0 ...

Add custom CMAKE_BUILD_TYPE (also see CMAKE_CONFIGURATION_TYPES):
cmake_minimum_required(VERSION 2.8.12)
project(foo)
set(CMAKE_CXX_FLAGS_MYREL "-O3")
add_library(foo foo.cpp)
output:
# Debug
# ... -g ...
# Release
# ... -O3 -DNDEBUG ...
# RelWithDebInfo
# ... -O2 -g -DNDEBUG ...
# MyRel
# ... -O3 ...
