用__attribute__((deprecated)) 管理过时代码,同一时候保留兼容的接口
Linux下:
#define DEPR_AFTER __attribute__((deprecated))
#define DEPR_BEFOR
class DEPR_BEFOR AAA
{
}DEPR_AFTER;
int main(int argc, char** argv)
{
typedef float T;
AAA aa;
return 0;
}main.cpp: In function ‘int main(int, char**)’:
main.cpp:16:9: warning: ‘AAA’ is deprecated (declared at main.cpp:9) [-Wdeprecated-declarations]
WINDOWS下:
对于VC。类似如OPENCV定义:
#if defined __GNUC__
#define __CV_GPU_DEPR_BEFORE__
#define __CV_GPU_DEPR_AFTER__ __attribute__ ((deprecated))
#elif defined(__MSVC__) //|| defined(__CUDACC__)
#pragma deprecated(DevMem2D_)
#define __CV_GPU_DEPR_BEFORE__ __declspec(deprecated)
#define __CV_GPU_DEPR_AFTER__
#else
#define __CV_GPU_DEPR_BEFORE__
#define __CV_GPU_DEPR_AFTER__
#endifC++库研究笔记--用__attribute__((deprecated)) 管理过时代码
