Title _PxImageFunc is an undefined reference
Ref. No. QNX.000009494
Category(ies) Development
Issue We want to include images in our Photon application.  The application is trying to load images using the PxLoadImage function. But, when we compile, we get this error:
x09_PxImageFunc is an undefined reference

How can we fix this?
Solution The _PxImageFunc is an undefined reference error is caused when you include the <photon/PxImage.h> file before you define the image modules that your application will support.


...

#include <Ph.h>
#include <Pt.h>

#define PX_IMAGE_MODULES    // define the modules we want
#define PX_GIF_SUPPORT
#define PX_JPG_SUPPORT
#define PX_PCX_SUPPORT
#define PX_BMP_SUPPORT

#include <photon/PxImage.h>
