ciao-install

    Running ciao-install fails with: 

    ERROR: Unable to retrieve ftp://cxc.harvard.edu/pub/ciao/all/ciao-control
ERROR: Unable to download ciao-control
ERROR: Bad Download. Please try again. If the problem continues Please
contact the CfA helpdesk.

Error in server response, closing control connection.

    These messages indicate a conflict in FTP configurations between the user's machine the the CXC. (This is often seen with home internet providers such as a cable company.) If you have access to another computer and/or IP address, e.g. in a university office, you can run ciao-install with the --download-only flag to get the tarfiles. Then transfer them, if necessary, to the home machine.

    If you do not have access to another machine or IP address, contact Helpdesk for help with the download.

    Mac OSX 10.8: incompatible libraries

     (15 Oct 2012) [New]

    Mac Mountain Lion, OSX 10.8, users will see a problem running the smoke tests for several of the GUIs. The behavior is the same as Lion (below) 

      [5/42] Running test obsvis-smoke004 .obsvis-smoke004.sh:
  line 57: 75615 Trace/BPT trap: 5       $OBSVIS_DS9 -source
  obsvis_test.tcl >> ${OUTFILE} 2>&1

    Workaround:

    Users will need to modify their CIAO installation to link certain libraries to the system version. 

    cd $ASCDS_INSTALL/ots/lib
mv libfreetype.6.dylib libfreetype.6.dylib.save
mv libfontconfig.1.dylib libfontconfig.1.dylib.save
ln -s /usr/X11/lib/libfreetype.6.dylib libfreetype.6.dylib
ln -s /usr/X11/lib/libfontconfig.1.dylib libfontconfig.1.dylib

    Mac OS X 10.7: incompatible library

     (15 Mar 2012) 
      [5/42] Running test obsvis-smoke004 .obsvis-smoke004.sh:
  line 57: 75615 Trace/BPT trap: 5       $OBSVIS_DS9 -source
  obsvis_test.tcl >> ${OUTFILE} 2>&1
    [New]

    There is a conflict between CIAO and a system library on OS X 10.7.

    If you run the smoke tests without completing the workaround, obsvis-smoke004 will fail and the diff file will contain a library error: 

    unix% cat /tmp/smoke.username/obsvis-smoke004/diff.log

< dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib
<   Referenced from: /usr/X11/lib/libXft.2.dylib
<   Reason: Incompatible library version: libXft.2.dylib requires
    version 14.0.0 or later, but libfreetype.6.dylib provides version
    13.0.0

    Workaround:

    The workaround is to rename the link libfreetype.6.dylib in ciao-4.4/ots/lib, and then create a new link to /usr/X11/lib/libfreetype.6.dylib: 

    cd ciao-4.4/ots/lib
mv libfreetype.6.dylib libfreetype.6.dylib.ciao44 
ln -s /usr/X11/lib/libfreetype.6.dylib libfreetype.6.dylib

    If you are installing CIAO with the ciao-install script, the suggested steps are:

    1. run ciao-install, answering "n" at the "Run smoke tests?" prompt
    2. complete the workaround
    3. run ciao-install a second time, answering "y" at the "Run smoke tests?" prompt

    When running 32bit smoke tests on 64bit machine, obsvis or sherpa smoke tests fail.

    This occurs when switching from a 32 to 64bit build (or vice versa), leaving incompatible .fontconfig files cached on the user's system.

    Workaround:

    Remove the .fontconfig cache: 

    unix% rm ~/.fontconfig/*

    and the GUIs should run.

ChIPS

    Runtime Error: Chips Error: Unable to connect to server  (15 Dec 2011)

    If the X server takes too long to initialize, the ChIPS smoke tests will fail with this message. Run the smoke tests a second time and the errors should go away.

    Gtk-Message: Failed to load module "gnomebreakpad": libgnomebreakpad.so:
    cannot open shared object file: No such file or directory
    OR
    Gtk-Message: Failed to load module "canberra-gtk-module": libcanberra-gtk-module.so:
    cannot open shared object file: no such file or directory
    OR
    Gtk-WARNING **: Unable to locate theme engine in module_path: "clearlooks"  (16 Apr 2010)

    The warning is cosmetic and doesn't impact how ChIPS works. It does, however, cause all the ChIPS smoke tests to fail, e.g.: 

    Running test chips-smoke001
chips-smoke001 FAILED
  Review /tmp/smoke.user/chips-smoke001/diff.log for details
make[1]: *** [test-chips-smoke001] Error 1

    Examining the diff.log files will show that the warning message is the only difference: 

    % cat /tmp/smoke.user/chips-smoke001/diff.log
3d2
< Gtk-Message: Failed to load module "gnomebreakpad": 
libgnomebreakpad.so: cannot open shared object file: No such file or 
directory
3d2

    Workaround:

    The gnome session sets GTK_MODULES to load some debugging tools. If the user simply unsets the GTK_MODULES environment variable, then the warning messages will disappear: 

    unsetenv GTK_MODULES


    *** Cannot find the double-buffered visual.
*** Trying single-buffered visual.
*** No appropriate OpenGL-capable visual found.
     (26 Jul 2010)

    The messages may be accompanied by a traceback error: 

    Traceback (most recent call last):
  File "/tmp/smoke.al/chips-smoke001/chips-smoke001.py", line 2, in <module>
    strip_chart(3)
  File "/usr/ciao-4.4/lib/python2.7/site-packages/pychips/extensions.py", line 3436, in strip_chart
    __pychips_base__.grid_objects(1, entries,0, gaps,1)
  File "/usr/ciao-4.4/lib/python2.7/site-packages/pychips/pychips_base.py", line 935, in grid_objects
    return _pychips.ChipsRemoteMod_grid_objects(*args)
RuntimeError: chips ERROR: No current window to perform operation on

    Workaround:

    • This error may indicate that the necessary graphics drivers are not installed on the machine running CIAO. For example, if you have a Nvidia graphics card and are running the 32-bit version of CIAO, you must have the 32-bit Nvidia drivers installed.

    • If you have SSH-ed into another machine to run CIAO, be sure that the -X or -Y (or both: "ssh -XY") options were used to enable X11 forwarding. If that doesn't resolve the issue, set 

      setenv LIBGL_ALWAYS_INDIRECT 1

      This should happen by default when logging into a remote machine, but occasionally the system needs it set explicitly.

    If this information does not resolve the problem, contact Helpdesk for additional diagnostic help.

    libGL warning: 3D driver claims to not support visual 0x4b  (15 Dec 2008)

    All chips smoke tests may fail due to this warning produced by some ATI graphics cards. The warning is benign and can be ignored.

    CIAO is installed as root and the Chips/GUI smoke tests fail  (16 Apr 2010)

    The ChIPS and the GUI applications, such as prism and obsvis, open windows as part of running the smoke tests. Often the root account is not allowed to open a window on the machine, which causes these tests to fail.

    The path to diff.log indicates this test was run as the root user: 

    /tmp/smoke.root/prism-smoke001/diff.log

    It is is strongly suggested that CIAO be installed as a non-privileged user and not as the root user. If CIAO must be installed in a directory owned by root and you are following the manual process, then

    1. unpack CIAO as root (so creating the ciao-<ver>/ directory);
    2. use the chown utility to change ownership of this directory to the installer's username.

    ChIPS smoke test comparison fails due to comma in place of decimal point  (02 Apr 2010)

    Some system languages (e.g. Italian) use a comma in place of decimal point by default. This will cause the ChIPS smoke test comparison to fail, because the file packaged with CIAO uses decimal points: 

    unix% cat /tmp/smoke.user/chips-smoke001/diff.log
5c5
<     Plot [plot1]   (0,15,0,65)  .. (0,90,0,90)
---
>     Plot [plot1]   (0.15,0.65)  .. (0.90,0.90)
11c11
<     Plot [plot2]   (0,15,0,40)  .. (0,90,0,65)
---
>     Plot [plot2]   (0.15,0.40)  .. (0.90,0.65)
20c20
<     Plot [plot3]   (0,15,0,15)  .. (0,90,0,40)
---
>     Plot [plot3]   (0.15,0.15)  .. (0.90,0.40)

    If the decimal point/comma difference is the only thing recorded in the log file, ChIPS is fine to use.

Sherpa

    Sherpa: "ERROR: test_image (sherpa.image.tests.test_image.test_image)"  (13 Jul 2010)

    The Sherpa smoke test fails and the log contains these errors: 

    ERROR: test_image (sherpa.image.tests.test_image.test_image)
----------------------------------------------------------------------
Traceback (most recent call last):
ValueError: total size of new array must be unchanged

    This is an intermittent error in the code that Sherpa uses to talk with DS9 via XPA. Run the smoke tests a second time and the errors should go away. If they do not, contact Helpdesk for further assistance.

    sherpa-smoke001 fails with an AssertionError  (13 May 2011)
    (Linux 64-bit) 

    .........................................ERROR: XSXSabsori model evaluation failed

AssertionError

----------------------------------------------------------------------
Ran 180 tests in 24.795s

FAILED (failures=1)

    Running the smoke tests again often reports a success for this test; the instructions for running smoke tests are in the Installing CIAO thread.

Prism

    (prism:2236): Gtk-WARNING **: GModule (/usr/lib64/gtk-2.0/2.10.0/engines/libclearlooks.so)
    initialization check failed: Gtk+ version too old (micro mismatch)  (01 Feb 2011)

    This warning messages may be generated when prism is run during smoke testing or run from the command line. The warnings are harmless, but annoying.

    Workaround:

    Remove or rename the $HOME/.gtkrc-2.0 and/or $HOME/.gtkrc-2.0-kde4 file to eliminate the warnings.

    Segmentation fault  (18 Feb 2010)

    The prism smoke tests will segmentation fault if there are incompatible .fontconfig files cached on the user's system. Remove the .fontconfig cache: 

    unix% rm ~/.fontconfig/*

    If this does not fix the prism problem, contact Helpdesk.

    CIAO is installed as root and the Chips/GUI smoke tests fail  (16 Apr 2010)

    The ChIPS and the GUI applications, such as prism and obsvis, open windows as part of running the smoke tests. Often the root account is not allowed to open a window on the machine, which causes these tests to fail.

    The path to diff.log indicates this test was run as the root user: 

    /tmp/smoke.root/prism-smoke001/diff.log

    It is is strongly suggested that CIAO be installed as a non-privileged user and not as the root user. If CIAO must be installed in a directory owned by root and you are following the manual process, then

    1. unpack CIAO as root (so creating the ciao-<ver>/ directory);
    2. use the chown utility to change ownership of this directory to the installer's username.

ds9

    The ds9 smoke test results may differ in the least significant figure. [New] (22 Dec 2011)

ObsVis

    Mac OS X 10.7: incompatible library

     (15 Mar 2012) 
      [5/42] Running test obsvis-smoke004 .obsvis-smoke004.sh:
  line 57: 75615 Trace/BPT trap: 5       $OBSVIS_DS9 -source
  obsvis_test.tcl >> ${OUTFILE} 2>&1
    [New]

    There is a conflict between CIAO and a system library on OS X 10.7.

    If you run the smoke tests without completing the workaround, obsvis-smoke004 will fail and the diff file will contain a library error: 

    unix% cat /tmp/smoke.username/obsvis-smoke004/diff.log

< dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib
<   Referenced from: /usr/X11/lib/libXft.2.dylib
<   Reason: Incompatible library version: libXft.2.dylib requires
    version 14.0.0 or later, but libfreetype.6.dylib provides version
    13.0.0

    Workaround:

    The workaround is to rename the link libfreetype.6.dylib in ciao-4.4/ots/lib, and then create a new link to /usr/X11/lib/libfreetype.6.dylib: 

    cd ciao-4.4/ots/lib
mv libfreetype.6.dylib libfreetype.6.dylib.ciao44 
ln -s /usr/X11/lib/libfreetype.6.dylib libfreetype.6.dylib

    If you are installing CIAO with the ciao-install script, the suggested steps are:

    1. run ciao-install, answering "n" at the "Run smoke tests?" prompt
    2. complete the workaround
    3. run ciao-install a second time, answering "y" at the "Run smoke tests?" prompt

    OBSVIS Error: Retrieving calibration updates from server produced the following error: 'Network timeout' [New] (27 Jan 2012)

    Occasionally the connection to the server times out during the smoke test before ObsVis can get the data it needs. Try running the GUI from the command line: 

    unix% obsvis

    If the problem persists, contact Helpdesk.
