Compiling from source with multiple libpng's
 

I have different flavors of libpng on my system. (No, I'm not sure why: but, I'm reluctant to force one off when RPMDrake says doing so will break dependencies...)

I recently compiled and installed a new app (KBear2-beta) and it reports:
"libpng error: Incompatible libpng in application and library
libpng warning: Application was compiled with png.h from libpng-1.0.12
libpng warning: Application is running with png.c from libpng-1.2.4"

This is under KDE 3.0.3, installed from Mandrake 8.2 RPMs.

Compiling from source is new for me:
(a) do I point ./configure at the libpng-1.2.4 library or
(b) do I do the above at the make stage

And: how do I do either one of those?

Sorry to be so "new", but I'm stumped...

Thanks much!

run ./configure --help for all the options that are available to you.
