I posted something earlier about this...
I've been trying to get QT to compile using cygwin. I've checked the
mailing lists and online information on porting it, and gotten pretty far,
but now i'm stuck on a problem I have no idea how to fix. It seems to be
trying to call a function that it can't find. I think(I'm a newbie at this)
that the '_imp__' prefix to all the errors means that its is trying to
access exported functions from another file.

>From what I can figure out the functions that it is trying to call are
located in 'src/3rdparty/libpng/png.c'. Has anyone come across this
problem, or know how to fix it? The header files include <png.h> in
qpngio.cpp, png.h has a bunch of stuff like this( which i have no idea what
it does, and therefore can't fix ):
/* Return the user pointer associated with the I/O functions */
extern PNG_EXPORT(png_voidp,png_get_io_ptr) PNGARG((png_structp png_ptr));
/* Fatal error in PNG image of libpng - can't continue */
extern PNG_EXPORT(void,png_error) PNGARG((png_structp png_ptr,
png_const_charp error));
Thnx for the help...
