Eric,
In all cases I install J in the default folder /Users/brian/ .
On my intel 64 Mac the install of j801 is not working: only jconsole will
open, not jhs and not gtk. When I launch either jhs801 or gtk801, I get no
terminal window to even open.
As a matter of fact, now that I have reinstalled j801, j701 jhs is not
working either, but both jconsole and gtk do work. When open jhs701 I get
the following error in terminal now.
brian$ /Users/brian/j64-701/bin/jhs.command ; exit;
|EADDRINUSE: sdcheck_jsocket_
| sdcheck_jsocket_ r
I thought that error message means another version of jhs is already
opened, but I have been very careful to close all such browser pages and
even emptied cache.
I am a little suspicious of a security issue on the Mac OSX 10.7.5 which
interrupts all of my attempts to open downloaded files. I am always now
presented with a Mac system dialog box warning that the file came from the
internet and do I really want to open it. But with this new download of
j801, no such dialog is presented. OTOH, I have not downloaded a j701 and
it not working either, but in a way that is different from j801 as I said
above.
The only thing I have editted in the j64-801/bin directory is profile.ijs.
In the file I changed the following line (\ to /). But the change does not
change any of the results I have described.
from:
userx=. '\j',('64-'#~16={:$3!:3[2),'801-user'
to:
userx=. '/j',('64-'#~16={:$3!:3[2),'801-user'
I am really disappointed that I cannot make this work, and especially that
I have even lost jhs701. I have been enjoying exploring webgl.
Thanks,
