Re: gtk version--importance of version 2.12 versus 2.10?

[John Darrington]

In pspp 0.6.2, if you pass --enable-anachronistic-dependencies it's supposed to 
relax the gtk dependency back to Gtk+-2.8 - however some features will then
be missing.  Also I don't think anyone has actually tested this flag recently.

Good luck.

     pspp INSTALL file says that gtk2 >= 2.12 is required, along with
     libglade > 2.6.
     
     In RedHat/Centos 5.4, the included version of libglade is sufficient
     (libglade2-2.6.0-2), but unfortunately the  version of the gtk2
     libraries is ancient:
     
     gtk2-2.10.4-20.el5
     gtk2-devel-2.10.4-20.el5
     
     My first try at this was last Friday.  I've had a somewhat strange
     experience.  I was building pspp from the Fedora repository SRPM.
     That SPEC file requires libglade 3, but that is a mistake ( 2.6 would
     suffice).  However, the newer gtk2 is needed.  I built a series of rpm
     packages that were needed to use a newer gtk2, including glib2,
     pango, libthai, gsl, gnutls, and some others I can't name.
     
     I was able to build & use pspp, but I caused some deep, deep trouble
     on that one workstation.  There were no RPM system warnings once I
     simultenously upgrades the packages (no "force" required).
     "Upgrading" glib & gtk2 seems to cause the system to become quite
     unstable--apps running on the screen randomly lose connection with the
     keyboard/mouse.   (gtk2-2.10 and 2.12 seem to use the exact same so
     names on shared libraries, so programs don't notice the mismatch??)
     The symptom of the problem is sometimes referred to as a "soft
     freeze," programs on the screen don't respond at the keyboard, but one
     can ssh into the machine and reboot or restart gdm. There is no
     evidence of a kernel freeze and no errors in the logs.  I suspected a
     hardware failure (sounds like bad RAM or MOBO to me), but diagnostics
     found nothing.  In the Internet, I found many complaints about random
     hangups with this particular kind of computer (DELL Optiplex 760), but
     I do not have any reason to say.  I re-mastered the operating system
     and now it does not hang any more.  That seems like pretty good
     evidence that the libraries were at fault.
     
     I can install the pspp RPM I built with gtk2-2.12 on a system that
     only has version 2.10, and psppire appears to run well enough.  There
     are no warnings about gtk version mismatches in the stderror. I
     include the ldd output below from that system, where the shared
     library set *appears* OK.
     
     That makes me wonder what elements in gtk+ 2.12 are needed in new-ish
     pspp, and why one needs 2.12 to compile, but only 2.10 to run pspp.
     
     This is from the pspp built against gtk2-2.12 but installed into the
     system that only has 2.10
