Errors importing after running macosx_setup.comman
Oct 11th, 2007, 4:59am  
Hi there,

In order to get the serial library working on OS-X, I ran the macosx_setup.command file and then rebooted.
After I started up processing again, it seems that any sketch which I run that tries to import a processing library fails with the message:

From what I have read online, these sorts of errors usually indicate that Java isn't in the path, but I am certain it it. As well, sketches that don't import any libraries seem to work fine (though have trouble running when exported...)

Anyone have any ideas how I could fix thie?  I have tried reinstalling java, and downloading different versions of processing...

Hmm, after experimenting some more and trying different $PATHs, I found that if I run processing by doing a "Show Contents" on processing.app, and running "JavaApplicationStub" it works just fine...
As far as I can tell this is like running it in the terminal.  Now if only I could figure out why I can't just double click on it....

that's awfully weird. what happens when you type "java" in a terminal window?

i don't suppose you installed one of the developer releases of java?

Typing java in the terminal gives me the list of java options (as it should), and java -version gives me:

java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-164)
Java HotSpot(TM) Client VM (build 1.5.0_07-87, mixed mode, sharing)

No developer version of java.

This is on a Macbook Pro with os-x 10.4 and all the latest updates.  

It almost seems as though $PATH isn't being used when I double click on processing.app....  The same problem appeared in mobile processing at the same time.  

It's very strange becasue running the macosx_setup.command and rebooting are the only things I did between it working and not-working.  I've tried undoing, and redoing the changes made by it, but to no avail (besides which, they look to be harmless changes...)

maybe try a blank processing sketch with:

println(System.getenv("PATH"));

and let me know what's inside? i'm pretty stumped on this.

Alright, I figured it out, and it was a result of me mucking around in ~/.MacOSX/Environment.plist .  I deleted some values in there that I thought were doing nothing, but the problem didn't manifest itself until I rebooted.  
So really it was not a problem with the setup.command, but with me having to reboot after it Wink
Oops.
Thanks for your help though!
