[kepler-users] Mac OS, Matlab, and library paths

[Joe Futrelle]

Hi, I'm trying to run Matlab codes from Kepler in Mac OS (Snow Leopard). As an inexperienced user I'm simply firing up the prepackaged Mac OS distribution of Kepler and double-clicking on the app icon.

It's no problem constructing a workflow with a "Matlab expression" in it, but when I run I get a stacktrace about the Matlab libraries not being on the DYLD_LIBRARY_PATH.

I'm having no trouble finding those libraries manually; they're right where they should be in my Matlab install, and they're 64 bit, and everything seems in order.

Setting DYLD_LIBRARY_PATH doesn't seem possible in Mac OS; I can set environment variables in launchd.conf, but launchd appears to silently ignore DYLD_LIBRARY_PATH; maybe it's special-casing it for some reason.

I'm having trouble finding a previous post on this list, or a bug in Kepler's bugzilla database, or a documentation section or FAQ entry that explains how to solve this. It's clear that some people have had problems with this in the past, but I don't see a clear description of what I should be doing. Any and all advice welcome.

Mac OS version: 10.6.7
Java version: 1.6.0_24 (Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode))
Kepler version: 2.2
Matlab version: R2011a
