I am a linux newbie. I use FC3. I wanted to install gtk+ 2.12.0. So I downloaded the source from gtk.org. While installing i realised that glib, pango, atk are also reqd. So i downloaded all of them and started off with installing glib. I installed glib into /usr (By installing into /usr i mean i put the prefix value of configure as /usr). I then installed pango and atk in that order. Assuming everything reqd. for the gtk installation has been done, i tried installing gtk. Here's the error message i got :

checking for BASE_DEPENDENCIES... Package cairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `cairo.pc'
to the PKG_CONFIG_PATH environment variable
No package 'cairo' found
configure: error: Package requirements (glib-2.0 >= 2.12.0 atk >= 1.9.0 pango >= 1.13.0 cairo >= 1.2.0) were not met:

So i downloaded the latest version of cairo and tried installing it into the same dir. (/usr again). Now, it needed libpng. So i downloaded libpng and installed it again into the same dir. (/usr). But I still get the same error message which is :
checking for cairo's PNG backend...
./configure: line 24790: --exists: command not found
./configure: line 24790: --exists: command not found
./configure: line 24790: --exists: command not found
configure: WARNING: Could not find libpng in the pkg-config search path
checking whether cairo's PNG backend could be enabled... no
configure: error: requested PNG backend could not be enabled

I am in a complete mess right now. I am not knowledgable enough to understand the error messages. Even if i understood it, I dont have the knowledge to correct the error. I browsed through all similar problems users encountered and didnt find any related to libpng etc.

I will be really thankful for any help.

Don't install things like glib or gtk from source. This is not necessary because Redhat uses intelligent package management software and glib and gtk are popular enough to find these packages out there. Download the rpm's and install them.

For RPM Packages I suggest www.rpmfind.net.When selecting the PAckage make sure that the distro and the arch r correct.

I've come across the same problem through trying to install Gnome Commander

Having spent 3 or 4 days trying to resolve it I've come across postings all over the net from people trying to resolve the same issue from FC3 right through to FC6, and it seems to affect a wide variety of programs

I've tried every 'solution' that I've seen suggested, installed packages through yum, downloaded rpms, downloaded packages as source code etc etc etc

Packages like cairo and libpng saying they can't be installed whilst at the same time saying they are installed and can't be UNinstalled because half the apps on the system depend on it (unless you specify --nodepends ... which unsurprisingly throws up yet more issues)

I've reinstalled FC6 three or four times in the process of all this to no avail

The conclusion I've reached as I've been unable to fix it myself and not one person I've seen posting about it on various forums has been able to either, that if you have this particular issue it isn't going to go away in a hurry, and as so many programs seem to depend on the libraries affected it almost makes using the os pointless

On that note, I'm off to install another flavour on the same machine ... with fingers crossed that I'll have more success!

Rune, the problems mentioned in the first post are solved by installing the corresponding development (devel) package of the package that the configure process said is missing. You can do this using YUM or YUMEX on Fedora Core.

Yeah I tried all that m8 and when I first ran into the problem, I did a fresh install and tried again, results were the same

I'm wondering if perhaps using the 32-bit version on an AMD 64 machine might've had something to do with it

I've put Ubuntu 64 on the same machine and installed the same packages without a glitch ... so far anyway!

I'm planning on trying the 64-bit version of Fedora on another drive in the same machine once I've played with Ubuntu a bit more to see if I get more luck

Thanx for the replies guys. I have decided to call it quits. I really dont understand what is going on. I have even tried installing using yum but could only manage to update to an old version (2.4.6). Still have to check if it works for the application i am going to install.

You need to update to a newer version of Fedora Core. Fedora Core 3 is now unsupported, so its unlikely that you will find any software repositories that contain new gtk2 rpms for FC3. Fedora Core is a fast moving distro and releases have a short life span.

Thank you once again, I will try installing more recent versions of FC.
