Changing topics back to the Nightly case where the job is started in a
crontab environment rather than on the normal desktop command line as
above, further research indicates it is possible to set DISPLAY for
such environments (assuming that DISPLAY exists at the time the
crontab job fires as is typical for my case). So I am going to try
that to see if that change plus the above setting of XAUTHORITY solves
the Nightly issue as well.
Thanks to that crontab change to define the DISPLAY environment
variable, all is now well with the Nightly case, see
<https://open.cdash.org/testDetails.php?test=598968882&build=5135648>.
So that appears to be the end of the configuration issues with the
Contracts.PLplot test, and my thanks to Brad for implementing this
test in the first place, and both Brad and Ben for some key help with
my configuration of this test.
So for others here that might be interested, Contracts.PLplot tests a
build of the stage/master/nightly/latest branch of CMake by using
ExternalProject_Add to git checkout a specified version of PLplot and
to configure, build, and install that version with user control of the
PLplot version selected for the test and the CMake options used to
build PLplot. So this test is good from the PLplot perspective
because it makes it more difficult for some new CMake development to
cause PLplot developers problems without us knowing it long in advance
of CMake releases. And it is also good from the CMake testing
perspective since it is a test that exercises a lot of different CMake
functionality in a realistic way (i.e., as used in a rather complex
build system, warts and all). Additional notes are (1) because of the
relatively small size of the PLplot project (despite its build-system
complexity) this test adds less than ~30 per cent to the overall cost
of building and testing CMake, and (2) this test should work on
essentially all platforms (the build of PLplot is known to work on at
least Linux, Mac OS X, Cygwin, MinGW-w64/MSYS2, and MSVC). So if
anyone else is interested in trying this test on their favorite
platform(s), feel free to contact me for help with configuring it and
overcoming any PLplot build failures in the unlikely event of you
encountering those.
