PxImage linking error   
Hi everyone,

On the lastest QNX 4.25 build:

I have compiled a source-code file using PxImage lib.
I have #include <photon/PxImage.h> in the source file.
I have full options for linking libraries: -l Aplib -l phrtlib -l phexlib -l phcontrib -l photon_s -l phrender_s

But, when linking, it show error: 
warning(1028): _PxImageFunc is an undefined reference
file /usr/lib/phexlib3r.lib(/src/photon/lib/exlib/PxImage.c): undefined symbol _PxImageFunc
(see my attached file below)
I have written PxImageFunc() myself on my code, but it happends again :)

So, how can I do?

Hi Cong,

Can you attach a small complete source example that illustrates the issue?

Respectfully,
Oleg

Re: PxImage linking error   
Cong,

You have to define both PX_IMAGE_MODULES and desired PX_XXX_SUPPORT macros to enable PXImage functionality. You can add 
the following line to your mf.7 file just after CFLAGS = ...

CFLAGS += -DPX_IMAGE_MODULES -DPX_GIF_SUPPORTED

The list of supported PX modules you can find in QNX Help Viewer in PxLoadImage() overview.

Respectfully,
Oleg
