Upgrade to Gtk 2.6 but keep my old Gtk 2.0?


Hi guys

I want to upgrade to the new GTK 2.6 - how can I do this WITHOUT losing my existing 2.0 library binaries?

I think I need to know where the existing 2.0 library binaries are on my Rh9 installation, and then somehow compile and install the new GTK 2.6 library so it does not overwrite the old one.

How can I do this and make applications' configure scripts find the GTK 2.6 even if it is not where they expect it to be (i. e. I did not allow 2.6 to replace 2.0, so configure scripts won't find 2.6 since it is in a "nonstandard" location?)

How thus can I keep my GTK 2.0, but also have GTK 2.6 on my system for applications that need them? How can I force a configure script to "find" either at my choice? I have legacy apps that use 2.0 that I suspect won't compile if I have 2.6. Other apps I need to run only want 2.4 or higher, and won't even configure with 2.0.

Any help appreciated - anybody tried this before?

Thanks!

Run the configure script for gtk+ 2.6 with the --prefix switch, like this:
./configure --prefix=/opt/gtk2.6
This will force the root of the installation to be /opt/gtk2.6 so the lib dir will likely be /opt/gtk2.6/lib, and so on.

Whenever you want an application to use the new libs, simply tack on the new lib directory to your $LD_LIBRARY_PATH:
LD_LIBRARY_PATH=/opt/gtk2.6/lib:$LD_LIBRARY_PATH mozilla
This will place the gtk2.6 lib directory before the regular lib directories in your $LD_LIBRARY_PATH (so the new ones are preferred) and then launch mozilla with these settings.

Similarily, to compile new software against the 2.6 libs you will need to pass the full path of the new lib dir to the configure script using the appropriate parameters (check the help options of the configure script).

most likely your old one is in /usr, so you need to pick a place (/opt/gtk-2.6 sounds good). I'd recommend giving it it's own directory like above, so if you want to remove it a simple "rm -fr /opt/gtk-2.6" and it's gone. you will also need to upgrade glib2, atk, and pango ( I'd install the all to /opt/gtk-2.6.

before you start, verify a file called xft.pc is in /usr/X11R6/lib/pkgconfig and do the following:
Code:
export PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig:$PKG_CONFIG_PATH
also go ahead and do the following:
Code:
export PKG_CONFIG_PATH=/opt/gtk-2.6/lib/pkgconfig:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=/opt/gtk-2.6/lib:$LD_LIBRARY_PATH
the first one tells pkg-config (the program the gnome libs (and some others) use to set up include and linking flags) where to find what it wants to compile the new libs. the second one appends /opt/gtk-2.6/lib as a path the linker needs to search ( both when linking libraries at compile time and at runtime). note that we're not using ldconfig.

for the commands ( the order is glib, atk, pango, gtk):
./configure --help ( look over your options, though most of the gnome libs these days are straight forward)

./configure --prefix=/opt/gtk-2.6
make
make install ( or optionally make a rpm and install it)

when you configure pango, when configure is done it will print a summary of what backends are to be built. make sure xft is listed, or gtk will refuse to use it.


when you are done, you will need to set up a couple environmental variables to force the system to ignore the default gtk-2.0 libs and use your new ones. to do this, you can add the following to /etc/profile or another script that /etc/profile sources for the variables to take effect when you login:

export PKG_CONFIG_PATH=/opt/gtk-2.6/lib/pkgconfig:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=/opt/gtk-2.6/lib:$LD_LIBRARY_PATH

you should be set with that, let me know if I forgot something.

Hi, people.
I just did everything that was described in the last posts.
Plus, i've added the environment variables to my /etc/profile and to ~/.bashrc.
The problem is, eventhough when i do "echo $LD_LIBRARY_PATH" it shows the correct path to /opt/gtk2.6/lib, gimp wont run, cuz it still thinks only the old gtk is installed. If, however, i do manually a "export LD_LIBRARY_PATH="/opt/gtk2.6/lib" it works fine! What am i doing wrong?

I'm on Slack10, kernel 2.6.11 btw.

Just one more thing. The output to "echo $LD_LIBRARY_PATH" is actually "/opt/gtk2.6/lib:", because i've added ":$LD_LIBRARY_PATH" to the end of the var value and it is undifined just before that line. Is there a problem?

Thanks!

** FIXED **
I just "su" and "ldconfig" and it all got fixed. Sorry about that, folks.

Anyways, now it can't recognize .jpeg files and there's also a few other Warning messages that make me uneasy... What should I do?

I could manage to solve that problem just now, i had a few packages missing from the gnome directory and also some other package that were not on the slack 10 cd. I did filename searches at the slackware site and downloaded the missing packages. All seems ok, but it still complains about some hi-color theme that i've already installed. Anyways it's just a warning.

Sorry about that folks, didnt mean to bother.

Shalom!

H Guys

Firstly to __J thanks!! that was so easy even I understood it... and this is my fist time playign with linux.. thanks again.

However, I am failing to install other GTK dependant things. for example I try to install the GTK-industrial-engine with the autogen.sh and get this:

Code:
/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/X11R6/include -I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/freetype2/confi g -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
checking GTK2_LIBS... -Wl,--export-dynamic -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0  -lgdk_pixbuf-2.0 -lm -lpangoxft-1.0 -lpangox-1.0 -lpango-1.0 -lgobject-2.0 -lgm odule-2.0 -ldl -lglib-2.0
./configure: line 20841: syntax error near unexpected token `1.2.9,'
./configure: line 20841: `AM_PATH_GTK(1.2.9, ,'
Can someone perhaps suggest why? I assume its because I havnt told the install where to find the proper GTK but I thought that adding the lines below to /etc/profile would have meant that I wouldnt need to change the configure every time I install a GTK dependant package.

export PKG_CONFIG_PATH=/opt/gtk-2.6/lib/pkgconfig:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=/opt/gtk-2.6/lib:$LD_LIBRARY_PATH

Thanks

=^_^=
