[expert] libpng not working in Mozilla/Galeon
Hello everyone, Hoping someone can shed some light on this problem. I recently upgraded (from Cooker) to Mozilla 0.9.5, and the latest Galeon as well. Along the way, I als ohad to upgrade libpng from version 2 to 3. Everything seemed to go well, I was able to meet all dependencies with a minimum of hassle, and libpng upgraded just fine. BUT ... now, neither Mozilla not Galeon are able to renger .png images! If I look in /usr/lib/, I can see both libpng2 and libpng3: libpng.so.2 -> libpng.so.2.1.0.12* libpng.so.2.1.0.12* libpng.so.3 -> libpng.so.3.1.2.0* libpng.so.3.1.2.0* I assume this is correct, because there are still many apps on my mostly-stock 8.1 system that require libpng2. I renamed the old libpng2 libraries, and made links with the same name to libpng3, but that did not seem to work. In fact, Galeon would not even launch! So, I named the libpng2 libraries back. At this point, I am at a loss, not knowing enough about how shared libraries work, and especially using different library versions. Any help? Dave -- Life is a series of rude awakenings. -- R.V.

What you actually have to do in the case of the libpng2 -> libpng3 shift (and many other major library upgrades, too), is to rebuild *all* of the libpng2-dependent apps against the new libraries. Often, this can be accomplished by simply downloading the src.rpm and issuing an rpm -bb command, but it can get a lot trickier hth -- john in syd Want to buy your Pack or Services from MandrakeSoft?

Doing a forced rpm install of cooker nautilus* got some of my icons back, but there are still problems. What application (or module) is actually responsible for drawing png's on the desktop so I can target that?

Mozilla 0.9.5 and Galeon (both from Cooker) required the libpng3 (from Cooker) in the first place! They shouldn't need to be recompiled. And I have had no problems with other apps using the older library, since both libraries currently exist on my system. What I am thinking is that somehow Mozilla/Galeon are loading the wrong version of libpng, and thus are not able to properly render .png images. Is there any way I can confirm if this is the case, or is there something I am missing? Dave -- Chemist who falls in acid is absorbed in work. msg44244/pgp0.pgp Description: PGP signature

You may very well be right. If X Windows is pre-loading the shared library, and only loads libpng2 but not version 3, then this could be the issue. Hrrmmm... wish I knew how to test this theory. Isn't there a way to use multiple versions of the same library? I am sure I read about that once! Dave -- I enjoy the time that we spend together. msg44307/pgp0.pgp Description: PGP signature

What you should have done was download the Mozilla .src.rpm, and rebuild it. If you had libpng2-devel installed (you might have to install some other -devel .rpm's), it would then require libpng2, not libpng3. Right now the one from Cooker requires libpng3 because that's what it was built against. As you found out, forcing an update from libpng2 to libpng3 is a bad idea... Generally it is best to rebuild anything from Cooker if you want to try it out (unless you're running a scrictly Cooker system to begin with).

Since I originally started this thread, I will tell you the solution someone else gave me: 1. Get the Mozilla RPM for RedHat 7.x and install/upgrade it. 2. I got a conflict with some library which I don't remember, but I forced the install anyway with --force. 3. Get the Galeon RPM for RedHat 7.x and install/upgrade it. 4. Enjoy!

why not just get the source for both and rebuild them yourself, you can even use checkinstall to add them to your rpm database mark On Tuesday 27 November 2001 19:41, you wrote: > On Mon, 2001-11-26 at 22:20, mike wrote: > > On Monday 26 November 2001 20:43, Tom Brinkman wrote: > > > On Monday 26 November 2001 09:24 pm, skidley wrote: > > > > I have both libpng2 and libpng3 installed here, there is no need to > > > > force an update they are 2 different libraries. > > > > > > Search 'libpng' on http://marc.theaimsgroup.com/?l=mandrake-cooker > > > and I believe you might come around to thinkin this is sor'ta kind'a > > > a naive notion ... you just haven't found out what you broke yet ;) > > > > > > Content-Type: text/plain; charset="iso-8859-1"; name="message.footer" > > Content-Transfer-Encoding: 8bit > > Content-Description: > > > > > > I hope this is not true, distinct versions of a library coexisting > > together is what makes Linux a more stable operating system, and avoids > > dll-hell.

In my case, I actually was going to try that route, but I didn't know where to look in Cooker for source RPMs. I was just browsing a Cooker mirror in Galeon, and all I saw were binaries. So, rather than spending a bunch of time trying to find the SRPMs, I got the RedHat binaries.
