This technique is worth knowing about: http://obvioushints.blogspot.com/search/label/J Running JLang on Snow Leopard<http://obvioushints.blogspot.com/2010/01/running-jlang-on-snow-leopard.html> by Alvaro Videla Thursday, January 14, 2010 Running JLang on Snow Leopard<http://obvioushints.blogspot.com/2010/01/running-jlang-on-snow-leopard.html> For this new year I started playing with J <http://www.jsoftware.com/>, a language that I discovered last year –but that I've never found time to play with–, while installing it, I had the problem that I didn't run on Snow Leopard.
After asking on twitter on how to solve this problem, @kaleidic<http://twitter.com/kaleidic>pointed me to this guide<http://www.jsoftware.com/jwiki/System/Installation/Mac/MacSnowLeopardInstallBug>, which tells you to modify the Java preferences to run in 32 bit mode. What I didn't liked from that approach is that it seems to modify the general preferences of Java. After some searches I found that there's an option for the *java* executable *-d32*, that makes it run in 32 bits. To apply this option simply go to the place where you installed *J* and there edit *bin/jwd*. In that file you will find a line like this: java -Xss8000000 -Xdock:name=J -Xdock:icon=bin/icons/jred.icns -jar bin/j.jar "$@" which you have to modify to: java -d32 -Xss8000000 -Xdock:name=J -Xdock:icon=bin/icons/jred.icns -jar bin/j.jar "$@" And that's it, then simply double click on the J icon and it should work as expected.
