Re: gtk install problems

[Peter <peterbohning gmail com>]

What does ABI mean?

What I would love is for someone to explain to me in the most
technical way possible why this is occurring.  Not different versions
of libraries, obviously I have different versions of libraries
installed.  And not some pkg-config thing because then the other
libraries shouldn't have compiled in the first place, that's what
pkg-config is for.  Even if pkg-config had the wrong path, if the
libraries were the wrong version the configure script should have
choked.

What's this thing with g_prgname?  Why would such a variable not hold
the same string across two accesses?  Is that because there's two
different interfaces to g_prgname and in my case those two different
interfaces are on libraries with incompatible versions?

What's confusing to me is that the configure scripts in gtk and glib
find the right libraries, they compile with those libraries, but then
programs that use gtk and glib don't run with strange errors.  Whether
or not I have two sets of libraries installed for the same software
seems irrelevant.

I initially recompiled X because something needed the X headers and
the header packages from Xorg didn't match my libraries and at this
point dselect (debian package manager) wanted to replace my kernel
because it wasn't what was expected.  I've compiled X before and it
wasn't and shouldn't be that much of a problem.

But please tell me something interesting.  Like that g_prgname thing,
how does that happen?
