Hi,
I forward this message from Prometeus Jasinski, since for some reasons he is not able to post in the forum.

My error on Fedora 20 is same as

https://root.cern.ch/phpBB3/viewtopic.php?f=3&t=18017&hilit=libp ng


When I install root with standard settings as a separate software I see
that libpng is linked against my machine libraries and I do not have
any problems opening the TBrowser.

When I compile fairsoft, libpng is not linked and the error mentioned
above occurs. I tried already to get rid of any root configuration that
might set internal linking stuff but I did not succeed. The output of
the library is not showing any relations to libpng:

One more information that might be valuable. The standalone software I
tested was /24 while the dez14 fairsoft contains /22. For the record, I
also tried the recommended fairsoft releases for pandaroot without
success.

Here I'm afraid I need help.



Any clues?
