Have you tested imdecode?

[dvazquez]

I am reading a JPG image from an SD card and want to use openCV, to create the Mat I need to call imdecode but I am having issues with library:

liblibpng.a(pngerror.c.obj):(.literal.png_free_jmpbuf+0x4): undefined reference to `__wrap_longjmp'

because I am not using png, could there be a way of ignoring that library?

I have that problem too, but I also get undefined reference to `typeinfo for std::basic_streambuf<char, std::char_traits >'
