Does not building against OpenCV 4.6 #71

Open OtacilioNeto opened 2 years ago

OtacilioNeto commented 2 years ago

DBoW2 does not build against OpenCV 4.6. Probably is broken with any version of OpenCV >= 4.

Yeah I also thinks so. I am trying to build it with opencv 4.4 and it is failing

in usr/local/include/DVision/BRIEF256.h add #include <DUtils/DUtils.h>, you can slove "error: ‘DUtils’ has not been declared".

I met the same error "/usr/local/src/DBoW2/DBoW2-1.1-free/include/DBoW2/FBrief.h:27:20: error: ‘BRIEF’ in namespace ‘DVision’ does not name a type; did you mean ‘BRIEF_t’? 27 | typedef DVision::BRIEF::bitset TDescriptor;", have you solved this problem?
