[Gvsig_english] gvSIG and Java on Mac OS X

Mon Oct 20 13:12:34 CEST 2008

OK. I have unbundled gVSIG and adapted the startup_script accordingly.

The only issues that still need to be resolved now are:

1. I cannot manage to get the shell script started from within the App
folder. It works fine from the command line, but a double-click on
the App package silently fails. I have created a minimal Info.plist
(attched) but that does not seem to do the job. Not sure whether the
problem is with that or with the shell script.

2. I actually don't know whether the SoyLatte JRE runs on PowerPCs
and 32Bit Intel. Could someone on those platforms test, please?

3. Minor cosmetic differences between using a system-wide JRE and
the bundled SoyLatte: SoyLatte does not apply transparency to the
UI elements. The main application menu bar also has the "X11" menu
instead of "gvSIG" (see attached screenshot). A more problematic thing
might be that there is no hardware-accelerated Swing UI with SoyLatte.
I do not know how badly that would affect the user experience, though.

I have uploaded a current version of the bundle here:

ftp://88.208.250.116/gvsig-unbundled.zip

Please test.

Given that it is impossible to resolve the Java situation consistently
on all variations of the Mac OS, I think there should be a choice for
users to run either the bundled SoyLatte JRE or the system-wide one
(particularly on OS X 10.5, as there is an "official" 1.6 JRE
available). This can be done easily by setting the "JAVA_VM=" variable
in the startup script.

How can I reliably check for the CPU architecture on Mac OS X (without
having to look it up in some C header file)?
