test_main.o:(.bss+0x0): multiple definition of `A::y'test_comm.o:(.bss+0x0): first defined here collect2: ld returned1exit status 下面通过匿名namespace解决这个问题,只需要把test.hpp的实现用匿名namespace包围即可避免重复定义的问题: --- test.hpp---#include<string>namespace{classA{public...
Anyway, your problem is that those nested structs are not confined in the outer struct's "namespace", because there are no namespaces in C. So you're redefining. If I may, it doesn't even make sense to define them inside a struct because they're not specific to that struct (at leas...

PROJECT_VERSION_TWEAK、<PROJECT-NAME>_VERSION_TWEAK 这些变量将有助于配置软件包,或将版本传递给编译文件,以便在最终可执行文件中可用。 遵循这一原则,我们可以设置DESCRIPTION和HOMEPAGE_URL,这将以相同的方式设置变量。 CMake 还允许通过enable_language(<lang>)指定使用的语言,这将不会创建任何元数据变量。 这...
