My app need a old version of "libpng"

[dcbasso]

Hello all,

Today I upgrade my computer, I make a rsync of everything from older computer (using OpenSuse 11.3, now I install OpenSuse 12.2), install the QtCreator (same as on the older computer) and try to compile and run my app...
So, I got no error at compiling time, but when I try to run the app I got this error:

libraries: libpng12.so.0: cannot open shared object file: No such file or directory

Well I check the version of this lib installed here, and I found the version "libpng14"...
How can I fix this problem, I know that I can install the version "libpng12" but I don't want to do that, how can I make my app use a new lib?

Thanks all...

Recompile Qt, possibly together with -qt-png to avoid similari issues in the future.

Appears to be easy to install the older libpng!
