I tried to compile an OpenCV VideoCapture example. When I compile it, I get the following output:
gpp test.c
Info: resolving vtable for cv::VideoCapture by linking to __imp___ZTVN2cv12VideoCaptureE (auto-import)
c:/programs/mingw/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe: warning: auto-importing has
enable-auto-import specified on the command line.
This should work unless it involves constant data structures referencing symbols from auto-imported DLLs.
(Btw, gpp is an alias of g ++ -lhighgui -lcv -lcxcore)
So, I tried to compile with "gpp -enable-auto-import", but g ++ did not recognize this option. So, I tried to compile like this:
gpp -c test.c
ld test.o
And I have the same error And many other errors about STL functions, indicating that they did not communicate with STL:
undefined reference to std::cout
...
And finally, when I compiled as follows:
gpp -c test.c
ld --enable-auto-import test.o
This time I got STL errors. Error VideoCapture has disappeared! So I decided that I solved this problem. The only thing: how to make ld a link to my program with STL libraries ??????
Thanks in advance
