Software requirements

Further considerations are required on Mac OS X in relation to X11 and Qt (see below).

SAOImage ds9

• ds9 stable version 3.0.3 works fine with SAS 7.0.0
• ds9 3.0.3 binaries are available here
• Latest beta version 4.0b9 seems to work fine as well.
• Each version of ds9 requires the xpa software, which can be obtained from the same site as ds9. For ds9 3.0.3 the required xpa version is 2.1.6. Notice that XPA is not part of ds9.
• Warning: xpa 2.1.6 does not work on Red Hat 9 and Fedora Core 1. For these systems please download xpa 2.1.6-2.

Grace

• SAS 7.0.0 works fine with grace 5.1.18.
• Source code for grace 5.1.18 can be found here

Heasoft

We recommend the installation of HEASOFT version 6.0 (HEADAS), since SAS 7.0.0 was built with that version (except for Mac OS X where version 5.3 was used).

Perl

The perl binary installed in your system must be adapted to work with SAS as /usr/local/bin/perl, either as a real binary or as a soft link to any other perl (typically in /usr/bin/perl).

On some GNU/Linux distributions you may have to create a symbolic link as:
ln -s /usr/bin/perl /usr/local/bin/perl

Requirements for Mac OS X

For SAS 7.0.0, as we did for 6.1.0, we have chosen X11 as the basis for SAS GUIs (e.g. sas, xmmselect, calview, odfbrowser, etc. Such choice has been possible thanks to the availability of Qt on X11 or Qt/X11, provided from the Fink software repository.

• X11

  To work with this release of SAS on any Mac OS X version, the X Windows software or X11 (a.k.a X11R6) for Mac Os X must be installed.

  Although this software is provided by Apple for each specific Mac OS X version, as far as we have experienced, the Apple implementation of X11 for Mac OS X 10.2 is incomplete and can not be used.

  However, that is not the case neither for Mac OS X 10.3.X(Panther) nor for 10.4.X(Tiger), where the Apple provided X11 software works fine.

  Therefore for Mac OS X 10.2, the only alternative is to install Xfree86 on Mac OS X as provided by Fink.

  For specific versions of Xfree86 for your Mac OS X version, please refer to this link.

  Notice that the installation of Xfree86 requires the deinstallation of the X11 from Apple or at least to rename /usr/X11R6. Look here for details.

• Qt

  There should not be any need to install Qt/X11 for Mac OS X since the SAS 7.0.0 distribution provides already a Qt library within the libextra tar.gz archive:

  • libqt-mt.3.2.2.dylib for the Mac OS X 10.2.X and 10.3.X versions
  • libqt-mt.3.3.5 for Mac OS 10.4.X.

  Then, if you install 7.0.0 on a Mac OS X 10.2 system, you do not need any additional installation of the Qt/X11 software.

  But unfortunately the libqt-mt.3.2.2.dylib library provided for the Mac OS X 10.3.X release can not be used on it. Thus, for Mac OS X 10.3.X you must install Qt/X11 version 3.2.2-12. This software will place the Qt/X11 library libqt-mt.3.2.2.dylib (and softlinks) in /sw/lib.

  For your SAS 7.0.0 binaries to take this library and not the already installed in $SAS_DIR/libextra, you need to modify the DYLD_LIBRARY_PATH variable as follows:

  • export DYLD_LIBRARY_PATH=/sw/lib:$DYLD_LIBRARY_PATH (sh/bash/ksh)
  • setenv DYLD_LIBRARY_PATH /sw/lib:$DYLD_LIBRARY_PATH (csh/tcsh)

  For Mac OS X 10.4.X (Tiger) there is not need to install any additional Qt software under Fink. Tests have shown that the Qt library libqt-mt.3.3.5.dylib provided with this release works properly on Mac OS X 10.4.X (Tiger). Notice than on this platform, you need to assure your DYLD_LIBRARY_PATH includes the $SAS_DIR/libextra directory. Such a setting is provided by the setsas.(c)sh scripts produced during the installation.
