Follows report of test suiet on Ubuntu 12.04, CentOS 5, CentOS 6, and
CentOS 7.  All CentOS installations are up to date with EPEL activated
for their respective versions.

General notes
-------------

Missing the following dependencies do not appear on the list of warnings
at the end of configure:

* libsndfile
* portaudio
* GraphicsMagick

There are a bunch of tests failing because although it was built with
portaudio, apparently there are "no audio devices found or available!".
Should these tests check for HAVE_PORTAUDIO and also if there's devices?

When X is not available but octave was built with native graphics (for
example, ssh without X forwarding), the plotting test are not skipped
and fail with "graphics_toolkit: fltk toolkit is not available".


Ubuntu 12.04.5 LTS --- AMD Opteron Processor 6284 SE --- gcc 4.6.3
------------------------------------------------------------------

Passes all tests with:

  * Native graphics disabled
  * Audio disabled
  * JIT disabled
  * GUI disabled


CentOS 5.11 --- Intel Xeon E5504 --- gcc 4.1.2
----------------------------------------------

Configured with:

  * GLPK disabled
  * GUI disabled (no mrc on Qt 4.2.1)
  * JIT disabled
  * Audio disabled (see bug #44976)

Throws loads of warnings (but I am building with gcc 4.1.2) of the type

  corefcn/symtab.cc:1517: warning: converting to 'int' from 'double'
  corefcn/oct-stream.cc:3212: warning: converting to 'char' from 'double'
  ./octave-value/ov.h:71: warning: 'class octave_value' has virtual
functions but non-virtual destructor

should I report these as bugs?

Failing tests:

  * chol.cc: hangs forever on test for bug #42587

  * legend, copyobj, and hgsave: these tests fail because of an old version
    of gnuplot installed.  Reported as bug #44978

  * sqrtm: maybe needs more tolerance

      ***** assert (sqrtm (2*ones (2)), ones (2), 3*eps)
      !!!!! test failed
      ASSERT errors for:  assert (sqrtm (2 * ones (2)),ones (2),3 * eps)

  * __osmesa_print__.cc: OSMesa too old, reported as bug #44979


CentOS 6.6 --- Dual Core AMD Opteron Processor 280 --- gcc 4.4.7
----------------------------------------------------------------

  * JIT disabled

Failing tests:

  * __osmesa_print__.cc: maybe needs more tolerance but may be related to
    a nvidia graphics card

    libGL error: failed to open drm device: Permission denied
    libGL error: failed to load driver: nouveau

Other problems:

  * ssh with X forwarding, starting with "octave --no-gui", causes exit
    of the ssh session to hang forever.


CentOS 7.1 --- Intel Core i5-2500K --- gcc 4.8.3
------------------------------------------------

  * JIT disabled

Test failures:
  * not failures but many tests (all related with figures) throw:

      XRequest.156: BadValue (integer parameter out of range for operation) 0x0

  * libinterp/dldfcn/__osmesa_print__.cc-tst: segfaults

Other problems:

  * ssh with X forwarding, starting with "octave --no-gui", causes exit
    of the ssh session to hang forever.
