I've received a few requests for the Mathematica installation procedure on OpenBSD, so I thought that I'd take a moment to post it on this mailing list. I have tested this procedure with Mathematica 6 on OpenBSD 4.4. I plan to experiment with Mathematica 7 on OpenBSD 4.5 in May, and will post my results. This procedure assumes that you are running OpenBSD 4.2 or later on the i386 architecture, and that you have a licensed copy of Mathematica 6 For Linux. I also assume that you have enabled compat_linux and have installed the fedora_base package, as described at http://www.openbsd.org/faq/faq9.html#Interact To install Mathematica, do the following: (1) Apply the patch at http://marc.info/?l=openbsd-misc&m=119479722118605 to the OpenBSD kernel. Instructions for downloading the kernel source code and building the patched kernel are available at http://www.openbsd.org/faq/faq5.html#BldGetSrc http://www.openbsd.org/faq/faq5.html#BldKernel (2) Create the directory /tmp/mathematica and copy the Mathematica 6 For Linux installation files into that directory. (3) The MathInstaller file should now be located at /tmp/mathematica/Unix/Installer/MathInstaller Type the following command to edit that file ed -s /tmp/mathematica/Unix/Installer/MathInstaller << EOF 1c #!/usr/local/emul/fedora/bin/sh . /DefaultManPageDir=/c DefaultManPageDir="/usr/local/man/man1" . g/Linux)/s/Linux)/OpenBSD)/ g/chgrp -fhR/s/chgrp -fhR/chgrp -fR/ g/chown -fhR/s/chown -fhR/chown -fR/ wq EOF (4) Make sure that you have superuser privileges, and run the installer by typing /tmp/mathematica/Unix/Installer/MathInstaller When you are prompted for Mathematica's installation directory, enter /usr/local/emul/fedora/usr/local/Wolfram/Mathematica/6.0 And when asked to create a new directory, type "y". Accept the default options at all subsequent prompts. (5) Again, make sure that you have superuser privileges, and edit the Mathematica executables by typing the following command. for i in math mathematica mcc Mathematica MathKernel do ed -s /usr/local/emul/fedora/usr/local/Wolfram/Mathematica/*/Executables/$i << EOF 1c #!/usr/local/emul/fedora/bin/sh . g/Linux)/s/Linux)/OpenBSD)/ g/cat .proc.cpuinfo | grep processor/s/cat .proc.cpuinfo | grep processor/dmesg | grep '^cpu[0-9]* at '/ wq EOF done (6) Mathematica's "Paclet" system requires Sun's Java binary, which does not function under Linux binary emulation on OpenBSD. See http://archives.neohapsis.com/archives/openbsd/2006-11/1099.html To disable the Paclet system, remove or rename the file /usr/local/emul/fedora/usr/local/Wolfram/Mathematica/*/Documentation/English/PacletInfo.bin (7) You are now ready to run Mathematica. The first time you start Mathematica, you need to change some of the default configuration options. In particular, on the menu at Edit > Preferences... > Internet Connectivity you should uncheck the box labeled "Allow Mathematica to access the Internet", since the Paclet system is required for that functionality. Furthermore, you need to configure the MathLink connection to use pipes rather than shared memory. The procedure for doing this varies, depending on which version of Mathematica you are using. On my version, I go to the Evaluation > Kernel Configuration Options... menu, edit the local kernel, click "Advanced Options" in the "Kernel Properties" menu, and change the word "SharedMemory" to "Pipes" in the "Arguments to MLOpen" box. You're done!
