I'm using openCV 2.4.2 with Qt 4.8.0
when i use the solvePnP function ,i get a error when i start the program ,it says "can't not find the entry point" ,about the libstdc++-6.dll
if i don't use solvePnP ,everything work fine.
so i compile openCV2.4.2 from source ,use compiler minGW 4.4 from qt , and get the library of debug and release version
it work with the debug version ,but crash with release version
i try to change option of makefile(use CMake 2.8)
- use static library -- fail to link
- change optimize level from O3 to O2 --still crash
- disable SSE & SSE2 -- crash
any idea? thanks for reading.
