Astronomical Image Processing System
Special MacIntosh OS X instructions
31DEC15 version of AIPS
is available as our active development version. It is likely to
change on a daily, weekly, and monthly basis. The older
31DEC14 version is "frozen"
although some patches for it may be made. They both contain ports
to the MacIntosh OS X (Darwin) operating system for PPC and Intel
cpus. These ports are no longer new and the code and instructions
below have become stable.. Binay installations,
where possible, are recommended and have become fairly routine. Users
doing a text installation will need to follow instructions to install
the full set of GNU compilers and readline from GNU-provided source
code. However, a binary installation is now available, including the
update process known as the "Midnight Job." The binary installation
provides load modules and run-time libraries build by the (somewhat
expensive) IBM xlf or Intel ifort compilers. These executables appear
to run up to 50% faster than those produced by the GNU
compilers. Most Mac users run the binary version of AIPS and the
instructions below may well not be current. Ignore them and simply
follow A Guide to the Install Wizard
unless you have to compile the code yourself.
The new Mac OS versions have caused some issues. Yosemite and El
Capitan both appear to delete some (not all) of the XWindows
libraries. See <
http:xquartz.macosforge.org/landing.> to re-install X11.
El Capitan also limits the use of run-time libraries. You may need
to copy of link (
ln -s) the libraries in the
$LIBR/INTELCMP directory into
/usr/local/lib to get AIPS to run.
Many thanks to Kristy Dyer and Michael Rupen of NRAO who loaned an
iBook computer for this development and who provided much need help
and encouragement in the process. Boyd Waters (NRAO) and Miguel F.
Morales (MIT) also provided considerable advice. Juan Cabanela (St.
Cloud State University) was at the forefront in dealing with problems
that arose therafter. A number of other Mac owners have also
contributed time and effort. Wes Young, formerly of the NRAO AIPS
Group, was instrumental in developing the binary installation process
and debugging recent OS/X issues.
Table of Contents
Binary installations of AIPS will need the basic tools "cvs" and
"XWindows" in non-developer form. If you are doing a text
installation, i.e. are compiling the code yourself, then you will need
Fortran and C compilers and a variety of software developers tools
including those for XWindows.
- Mac OS X Developer Tools: You will need the basic software
developers' kit from Apple. It contains the C compiler and
lots of other goodies, and is available for free. The
developers' kit may be available in
"/Applicatons/Installers/Developer Tools". Use the finder to
see if it's there, click on Applications, then Installers,
then Developer Tools. If it exists then double click on the
package icon and install the compiler. If the Developers'
Tools are not available on your hard drive, they may be
available from CD if you bought Jaguar or Panther. If you
have the CD's locate the Developers' Tools CD (Xcode disk for
Panther) and install the "Developers' Tools" package from
disk. One final place to get the "Developers' Tools" is from
the Apple Developer Connection (ADC). Details on the ADC are
available at the ADC
membership page, while details of the Developer Tools are
available at the tools
page. Once you're a member, you can go to http://connect.apple.com
site log in and snag the software.
- You will need XWindows for either a binary or a text
installation. With the Panther (X 10.3) version, X11 is
installed from disc 3 of the Panther distribution. The
developer tools may be installed from the Xcode CD.
Alternatively, the sites mentioned below may be used to
- Apple supplies X11R6. Go to the X11
download page and click on "Download X11". Do the usual
installation by clicking on the icon of the downloaded
object. Note that the version of X11 now available only
works on Panther. Jaguar users see below.
- For a text installation, you also need the XWindows software
developers kit which contains the C include files needed to
compile XAS. Apple gives this away too. Go to the main X11 page.
At the bottom to the very right hand side is, in small
letters, a button to click which will download the SDK.
Do the usual installation by clicking on the icon of the
- Jaguar users may obtain X11 via sourceforge. The easiest way
to do this is to grab
XonX. Go to XonX
homepage and get
Download of X11 4.3.0. That is a simple Mac Installer
based package for installing X11 including all the libraries.
Next, you need a simple Xserver window server. The most
"mac-like" one other than Apple's is OroborusX available at:
homepage. It provides a nice installer and users can
then just double click the OroborusX application to launch
their X11 server.
- Download the GNU tar balls from GNU or, more simply, from NRAO. They are
(31548232 bytes) and
- Disable the line
source /sw/bin/init.csh; rehash
from your account's .tcshrc, .cshrc, or
.bashrc file if present.
Note that this may have dire consequences for other
Fink-supplied utilities and is probably not needed any more.
The default Fink gcc has also been of an acceptabloe flavor
- Install the compilers using
sudo gnumake install
- Install readline using
setenv CC /usr/local/gnu/bin/gcc
./configure --prefix=/usr/local/gnu --with-curses --disable-shared
sudo gnumake install
- Intel sells a compiler designed for Intel chips running
under Mac OS/X. The latest versions have been
problematical. They apply rules of the latest Fortran
standards rather strictly without options to ignore some
or all of them. AIPS fails to compile with such rules even
though it works just fine. Users who tried Intel compilers
finally reverted to GNU compilers.
- IBM sells a Mac OS/X version of their xlf compiler but it
does not work for the new Intel chips used in Macs. This
has produced improved performance in our tests and is now
- Go to IBM
and fill out their marketing survey to get a temporary free
trial version of the compiler.
- Install it following IBM's instructions.
- We have made binary versions of the Mac load modules build
with the xlf compiler available to our users, including the
necessary run-time libraries. This is now offered for the
31DEC05 and later releases.
- The file systems that you use for AIPS should be fully
modern ones. Please use "MACos extended, with lower-case
support" file systems. The "FAT32" file system does not allow,
among other things, the rename system operation which AIPS
- Following the instructions for
installing the 31DEC15 version of AIPS. After
install.pl has been downloaded, it will need to
be made executable. Run it with the command
install.pl or edit it to set /usr/bin/perl rather than
/usr/local/bin/perl in its first line. (The command
perl install.pl -n is used for the binary
- Make sure on screen 10 that readline points to the
- When the installation has finished, copy /etc/services to
some area you own and edit it, adding the lines
sssin 5000/tcp SSSIN # AIPS TV server
ssslock 5002/tcp SSSLOCK # AIPS TV Lock
msgserv 5008/tcp MSGSERV # AIPS Message Server
tekserv 5009/tcp TEKSERV # AIPS TekServer
aipsmt0 5010/tcp AIPSMT0 # AIPS remote FITS disk access
aipsmt1 5011/tcp AIPSMT1 # AIPS remote tape 1
aipsmt2 5012/tcp AIPSMT2 # AIPS remote tape 2
You will have to comment out some conflicting services, all
of which we believe are obsolete. Then
sudo cp services /etc
and enter your password when required.
- Start up
- In the xterm that this creates, type the aips command line
and begin your aips session.
- If things do not work properly, e.g. the TV does not start,
see the AIPS Manager FAQ for
suggestions. On leopard systems, you will need to reset the
DISPLAY environment variable
setenv DISPLAY localhost:0
in the xterm that you run aips from to get the local tv. Ob
later systems, do NOT set the DISPLAY variable since that
will make everything fail.
- The default Mac system limits shared memory pages to 4
Mbytes. When XAS starts it tells you that it is making a
screen x pixels by y pixels. The memory you will need is at
4 x y bytes. For the new large screens
this is more than 8 Mbytes. On Panther stsems (X 10.3), you
can change this limit by changing (as root or admin) the rc
file in /etc, adjusting the
#Setting the shared memory to something a bit more reasonable.
sysctl -w kern.sysv.shmmax=10485760
sysctl -w kern.sysv.shmmin=1
sysctl -w kern.sysv.shmmni=32
sysctl -w kern.sysv.shmseg=8
sysctl -w kern.sysv.shmall=4096
- On the latest "leopard" systems, /etc/rc is gone and
creating it will have no effect. You need to create an
/etc/sysctl.conf file and put the values in it,
You should use the values you had when you were running
tiger. Those could be in /Previous\ System/etc/rc, assuming
you have "Previous System". So three different OS upgrades
and three different ways to adjust the default shared
- On older Jaguar systems (X 10.2), you can change this limit
by changing the SystemTuning file in
Look for the lines
sysctl -w kern.sysv.shmmax=4194304
sysctl -w kern.sysv.shmall=1024
Change the 4194304 to 10485760 (for 10 Mbytes) and
change the 1024 to 4096 (allows 16 Megabytes).
- Note that you must re-boot the computer after making the
above changes to the shared memory.
If your site has a need for the current version of AIPS with
updates via the Internet and the so-called midnight job, Read this information. It has additional
information and instructions. Or contact Eric
Greisen for further information.
Since releases of AIPS are planned to be only on an annual
basis, the midnight job (now with easier setup and NO ssh) will be the
only way for AIPS users outside of NRAO to avail themselves in a
timely fashion of whatever enhancements, changes, or new functionality
we add to Classic AIPS.
