Hi all. I found a sort of duplicated declaration while I was digging opencv test code. I use Windows7 + cmake + vs2012 with opencv 2.4.7. In ts.hpp,
// ts.hpp
// ...
namespace cvtest {
// ...
class CV_EXPORTS TS; // declare
// ...
class BaseTest; // declare
class TS; // duplicated declare (?)
// ...
class CV_EXPORTS TS { /* ... */ } // definition
class CV_EXPORTS BaseTest { /* ... */ } // definition
// ...
}
// ...
So, I deleted "class BaseTest;" and "class TS;" lines then compiled. Everything was going well. Are there other reasons for remaining these?
