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 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.

[jasinski@localhost root]$ ldd lib/ =>  (0x00007fff1abfe000) => /home/jasinski/bin/root/lib/

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:

[jasinski@localhost FairSoft]$ ldd $ROOTSYS/lib/root/ =>  (0x00007fff491fe000) =>
 (0x00007fd226a5b000) => /home/jasinski/bin/buildFairSoft/lib/root/

 	/lib64/ (0x00007fd227662000) => /lib64/ (0x00007fd2234c0000)

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

Here I'm afraid I need help.

Any clues?
