**Contents** [[!toc levels=3]] # Things needed the latest stable NetBSD/i386 installation. The archivers/{zip,unzip} packages. The linux emulation packages suse_base and suse_compat. If you want to run binary modules (MEX), you also need the suse_devel-7.3 package; that is not (yet?) available as suse9.x version. Matlab 14.3 ships with a JDK 1.5 which runs nicely on netbsd-3, so no additional JRE needed. The three Matlab 7 / R14 Unix installation CDROMs. The patches listed below. A few GBytes of diskspace. # Work to do # A Short Cut While the following steps are kept for documentation and your own experiments, there is a [tar-ball](http://www.spg.tu-darmstadt.de/~hf/notes/patch_matlabcd.tar.gz) available with the patches and a shell script to apply them. Unpack, change to the patch_matlabcd directory, call sh patch-matlab.sh -m /path/to/cdcontent, optionally add '-v' for verbose output. # Footwork * Copy the three CDROMs to the harddisk (directories CD1, CD2, CD3). * mount_union(8) a scratch directory on top of the directory that contains CD[123]. This scratch directory will contain all the changes that you make to the content of the CDs. * chdir to CD1 * Apply the patch

Provide a proper license.dat, and you are ready for installation. chdir to the installation directory, call the /path/to/install script from CD1, and click OK a few times. At the end of the installation, there is a spurious rm -f with empty argument that can safely be ignored. If you find out where it hides, please tell me. * OK, there's still the license manager... FlexLM comes with a byzantine set of shell script tools. Of course, there is one more arch.sh to patch, this time under {MATLABHOME}/etc/util/arch.sh. Then create /usr/tmp, preferably as a symlink to /var/tmp, because FlexLM and the MLM backend have that hard-coded for logs, locks, preferences. Make sure you have got a proper license file in place - the procedure is well-documented. After that, you can either start the flexlm daemon from /etc/rc.local by using {MATLABHOME}/etc/rc.lm.glnx86 start|stop, or with the following rc.d script : #!/bin/sh # # $Id: how_to_run_matlab_r14.3_on_netbsd__92__i386.mdwn,v 1.2 2012/02/05 07:14:36 schmonz Exp $ # # PROVIDE: flexlm # REQUIRE: DAEMON . /etc/rc.subr name="flexlm" rcvar=$name flexlm_user="flexlm" matlabroot="/path/to/matlabr14" lm_license="${matlabroot}/etc/license.dat" required_files="${lm_license}" command="${matlabroot}/etc/glnx86/lmgrd" command_args="-c ${lm_license} -2 -p -l +/var/log/flexlmlog" load_rc_config $name run_rc_command "$1" -- you need to create a user to run flexlm as, and own the logfile to him. # Other patches # arch.sh For whatever reason there may be, a Matlab 14 installation has three instances of the arch.sh script that works out what platform Matlab is running on: > find . -name arch.sh -print ./bin/util/arch.sh ./etc/util/arch.sh ./update/install/scripts/arch.sh And (of course) the one that is sourced by {MATLABROOT}/bin/matlab is the original version which you should replace by e.g. {MATLABROOT}/etc/util/arch.sh once you get tired of adding -glnx86 to every matlab invocation. # MEX If you want to build binary modules with mex you need to make sure those modules (libraries) are linux libraries since you cannot use native NetBSD libraries with a program running in emulation. Make sure you install the suse_devel package as listed above, and apply this patch to {MATLABROOT}/toolbox/matlab/general/mex.m. It makes sure the mex shell-script (which calls the compiler) is executed by the linux shell. # Sound Add a symlink to the native /dev/sound like [hf@dreispitz] /<1>linux/dev > pwd /usr/pkg/emul/linux/dev [hf@dreispitz] /<1>linux/dev > ll audio 0 lrwx------ 1 root wheel 13 Sep 10 03:25 audio -> /../dev/sound # Linux pthread libs Matlab 13, at least, expects the pthread shared library under /usr/lib whereas NetBSD's suse*_base package installs it under /lib.

For a shell exit, it populates LD_LIBRARY_PATH like >> !echo $LD_LIBRARY_PATH /opt/matlabr14/sys/os/glnx86:/opt/matlabr14/bin/glnx86:/opt/matlabr14/extern/lib/glnx86:/opt/matlabr14/sys/java/jre/glnx86/jre1.5.0/lib/i386/native_threads:/opt/matlabr14/sys/java/jre/glnx86/jre1.5.0/lib/i386/client:/opt/matlabr14/sys/java/jre/glnx86/jre1.5.0/lib/i386 >> [NetBSD ELF](http://www.netbsd.org/Documentation/elf.html) binaries do not normally use LD_LIBRARY_PATH; instead, NetBSD compiles fixed library paths into shared libraries and applications. Nevertheless, non-setuid NetBSD binaries still look at LD_LIBRARY_PATH. The above path apparently confuses complex NetBSD binaries like NEdit, XEmacs, Mozilla, which try to pick up Linux libraries instead of the native ones. As a workaround, unset LD_LIBRARY_PATH before calling the application, either with per-application wrapper scripts, or a generic wrapper script like #!/bin/sh unset LD_LIBRARY_PATH exec "$@" # OpenGL Commands like bench that use OpenGL result in a [kernel panic](http://mail-index.netbsd.org/port-i386/2005/10/07/0004.html) . Christos Zoulas has provided a [kernel patch](http://www.spg.tu-darmstadt.de/~hf/notes/matlab7_opengl.patch). It is against 2005-10-10 NetBSD-current source and applies with offsets to the netbsd-3 branch; apply from within sys/arch/i386/. The patch avoids the panic; what functionality exactly is missing remains to be seen. _Workaround_: The Matlab command opengl software enforces software rendering which is slower than using hardware support - but appears to work, unlike the latter. You still need the kernel patch, though, as any OpenGL operation will panic otherwise. # Issues left Why Mathworks duplicate their set of install scripts everywhere and still keep a zipped copy around to drop on top of the installation is beyond me. The diffs above are clean and minimal - it's just that you have to have five instances of each. --Hauke Fath
