Hi Orion:
Thanks for your 5.9.8 test results. More below.

I am concerned about the above WARNING message. If you look at
plplot_test/plplot-test.sh.cmake, line 357 you have the following
case "$device" in
png|pngcairo|jpeg|xfig|svg|svgcairo|bmpqt|jpgqt|pngqt|ppmqt|tiffqt|svgqt|epsqt|pdfqt)
options="-fam -fflen 2"
;;
This works here (Debian Squeeze) so that familying is used for all -dev pdfqt
tests so I never see that warning message. So why doesn't that work there?
All the shell scripts in
question start with
#!/bin/bash
so bash should be invoked on your system and do the right thing unless
Fedora has /bin/bash symlinked to something other than bash?
I would appreciate you investigating this puzzling result on Fedora further
by running plplot-test.sh by hand for cmake option -DBUILD_TEST=ON.

DISPLAY has to do with X. Could this segfault be related to the fix that
Andrew just committed to turn off X for Qt for noninteractive tests?
What happens if you use plplot trunk? Does that fix help?

Qt4 comes in two versions (debug and optimized). I wonder if that
undefined symbol is caused by inconsistent linking of the two versions
on Fedora for qt.so? From my understanding of the discussion on the
CMake development list this choice of debug or optimized Qt4 is the
source of a lot of CMake/Qt4 issues. There is one simple bug fix for
CMake itself that is required to help sort out Windows problems with
choosing a consistent version for Qt4, but I wonder if it might also
be relevant to Fedora as well? Anyhow, I suggest you try
http://cmake.org/gitweb?p=cmake.git;a=commit;h=5a2b20 (a three-line
patch to one of the CMake run-time module files) to see if it makes
any difference. My understanding is that patch is almost a sure thing
to go into CMake 2.8.6.
The patch is for CMake-2.8.5, but if Fedora is using some version less
than that, that might also be a source of additional Qt4 trouble.
