How do you set GDB debug flag with cmake?
提问by Fantastic Mr Fox
I have tried setting the debug flags using the
我曾尝试使用设置调试标志
set
command in cmake
but I cam unsure what to add. I have been told things like DEBUG=true
but so far i am unable to find the correct flag to set.
命令,cmake
但我不确定要添加什么。有人告诉我这样的事情,DEBUG=true
但到目前为止我无法找到要设置的正确标志。

If you want to build for debug (including source information, i.e. -g) when compiling, use
如果要在编译时为调试构建(包括源信息,即-g),请使用
cmake -DCMAKE_BUILD_TYPE=Debug <path>
If you want to build a release build, you can use
如果要构建发布版本,可以使用
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo <path>

Alternatively you can use the CMAKE GUI to make this change. Doing ccmake
with the project will yield a screen similar to this:
或者,您可以使用 CMAKE GUI 进行此更改。做ccmake
该项目将产生类似这样的画面:
Entering Debugin the CMAKE_BUILD_TYPE
field will allow you to build with debug flags.
在该字段中输入DebugCMAKE_BUILD_TYPE
将允许您使用调试标志进行构建。
