Thanks. You're right. This has got to do with how apps get launched in mac.
To get this to work you can fiddle with either launchd.conf or launchctl
(man launchctl). I added launchctl to the end of my .zshrc file and it now
works. This is the line I added:
launchctl setenv PATH $PATH
and the Jqt.
A simple suggestion you might not be thrilled about, there could be a 2nd
jconsole (named jqtconsole) that could link to all of the non-graphical qt
components, and/or jconsole could have command line switches that loads timers
or websockets.

Since jqt and jconsole use the same j engine so I think this is un-related
to J itself.

In j7, gtk is started by jconsole, but all Qt applications must be started
from executables that have static linked a small piece of Qt lib. I think
it is possible to build a jconsole with Qt lib so that it can use some Qt
facilities. However not everyone want this dependence.

Hi all,

Here's an example shared object compilation and use from j version 8.
Other examples exist at rosettacode.org. On the Tasks page search for
"call". If, on the other hand you want to embed j in another language

Yes, I'd go along with that. Splitting
Tricky; since no QApplication has been created, there's no event loop
nor container for instantiated widgets. As such, the majority of wd
commands will fail (either segfaulting or aborting jconsole)

I doubt there's anything wrong with Devon's installation; the libjqt
library path isn't set when IFQT is false (see stdlib.ijs).
Also note that even if you revise the path in wd1 after loading the
IDE library, GUI bindings won't work as the requisite setup (provided
by jqt) isn't in place.

What I want is a few pieces of Qt functionality that use "wd" - like

I don't have access to a jqt implementation right now to try this on, but

Could you please clarify the issue here? (Do you want a dedicated plot
window rather than your default PDF/image viewer to display the
chart?)

The thing I find annoying is that with the gtk graphics, I could call
graphical things from the console. Qt breaks attempting to define "wd":
load 'd:\users\devonmcc\j64-802\addons\ide\qt\qt.ijs'
|domain error: wd1
|wd1[0]
13!:1''
|domain error
*wd1[0]
| 'r c l p n'=.wd1(,y);(#,y);
Yes - websockets was my motivation but I'm willing to work with something
more limited and primitive if I can continue in emacs: I'm attempting this
in SSE (server-side events) now.

Well I think this is a broader problem ... jconsole is a sort of
second-rank citizen, while it comes in really handy when GUI's are
inaccessible or clumsy to tackle. Eg. I might be working in jconsole, but
