Problem with two versions of glib...

["Henry W. Peters" <hwpeters jamadots com>]

Hi,

I am not sure this is the exact list to bring this up with, so please feel free to redirect me & my problem (appropriately).

I was in the process of building Ardour, which uses GTK, the below pasted dialogue shows, what I think is my problem. I have done this before, going to the GTK web site, getting the dependencies, working my way to the GTK libraries themselves. Short of story, I now have two versions of glib on my Linux Debian Lenny system... both have what it looks to me, to be (somewhat differing) critical dependencies... (GNOME desktop, etc.). My question is: How do I get rid of one of them (probably the earliest version, which is 2.22.0), with out destroying my system? 

Thanks much in advance, for any help.

Henry

Looks like you have a confused glib installation! It appears you might
have components of two different versions of glib on your system.
Specifically, your pkgconfig file seems to be indicating glib 2.22.0,
while the actual library appears to be reporting 2.22.3.

Your best bet is to fix your glib installation.  Barring that, you can
manually edit your broken pkgconfig file, which on my system is
located at:
/usr/lib/pkgconfig/glib-2.0.pc.

This might break other builds on your system, and is not in any way a
"fix", but should get your build to work.  Change the "Version: line
to match the version of your installed library, which in this case,
looks like 2.22.3.  Of course, this approach guarantees that you will
have a broken glib installation until you fix it!

Note, you should be able to test what pkg-config returns by manually
executing the line:
$ pkg-config --modversion glib-2.0

Better yet, fix your glib installation!  ;) 

Hope that helps.
