Description of problem:

ROOT can't write png images because it seems to be built against libpng 1.2 (F17 comes with 1.5) 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. run "root"
2. enter the following code
TCanvas c("c","c",500,500);
TH1F histo("histo","histo",100,-5.,5.);

Actual results:
A warning message is printed:
libpng warning: Application built with libpng-1.2.44 but running with 1.5.10
Info in <TCanvas::Print>: file gauss.png has been created

But gauss.png is empty

Expected results:

gauss.png should not be empty

The latest root build in Fedora 17 is already built using libpng 1.5. However, root does not use libpng directtly, but uses it through libAfterImage. The libAfterImage package is not yet rebuilt using the new libpng package.

Reassigning to libAfterImage.
Comment 2 Mattias Ellert 2012-05-02 22:53:06 EDT
A patch to build libAfterImage with libpng 1,5 can be found in gentoo: 


If I rebuild libAfterImage with this patch root starts working again.
Comment 3 hansvon 2012-05-08 04:09:59 EDT
Thank you. I confirm that the patch is working. I hope the maintainer of libAfterImage can rebuild the F17 package at some point.

I always updated my system, but I still had this bug and with every opening of new instance of TBrowser the error message "libpng warning: Application built with libpng-1.2.44 but running with 1.5.10" got created several times...

For me the problem was solved with updating the package libAfterImage as described in comment #7: 
   # su -c 'yum update --enablerepo=updates-testing libAfterImage-1.20-5.fc17'

So far so good, but this announcement was a month ago and in all these days the fix wasn't pushed into the "normal" repo. So please do so, otherwise a lot of people are forced to search for this bug report, like I was. The solution could be made very more easy.

Thanks a lot for your work, I appreciate that! ;)
Comment 10 nvwarr 2012-06-29 01:22:50 EDT
I second that. libAfterImage-1.20-5.fc17 also fixes my problem of creating .png files and, yes, I also noticed the problem with TBrowser. That is also fixed.
