Install FlyCatprue2 to the folder "C:\PointGreyResearch\"
Add the following to the .pro file:
# Add FlyCapture2 INCLUDEPATH += C:\PointGreyResearch\FlyCapture2\include INCLUDEPATH += C:\PointGreyResearch\FlyCapture2\include\C LIBS += "C:\PointGreyResearch\FlyCapture2\lib\C\FlyCapture2_C.lib" LIBS += "C:\PointGreyResearch\FlyCapture2\lib\C\FlyCapture2GUI_C.lib"
Note:
The C++ library only works with visual studio on Windows, not MinGW. So if we want to use MinGW, only the C library would work!
Sample FlyCapture2 API C Code:
