Greetings,
I'm working on an FLTK app that so far, has been ported and works quite
nicely on OS X. I'm not actually developing it, but I'm working on
finding solutions for a few issues we're having with this OS X version
for the developer while he's polishing up the Windows and Linux
versions. My developer experience on OS X is quite limited, please
forgive any newbie gaffes (my other hat is design/marketing).
The beta download page for the application is here:
The application is a encrypted anonymizer that creates a SSH tunnel
between the client machine and our proxy servers in Europe, anonymizing
the network connection and protecting it from local eavesdroppers. It
uses FLTK for the GUI, which controls the OpenSSH tunnels.
The app bundle executes a shell script (Tunneler.sh) that does does some
maintenance (I admit that I don't know exactly what it's doing - but it
looks like it's doing more than just setting environment variables) and
then launches the FLTK application (a FLTK Carbon app called
metropipe_tunneler).
This all works just fine if the application is launched from the Finder,
but there are a couple problems that arise when interaction with the
Dock is considered:
1) If the application is added to the Dock by dragging from the Finder,
when the Tunneler is launched from the Dock, it launches the
metropipe_tunneler FLTK application, which appears in the Dock - leaving
what appears to most users as two running Tunnelers in the dock.
(In this situation, the _CFURLString in com.apple.dock.plist =
/Applications/Tunneler.app)
2) If the user launches the Tunneler from the Finder, then adds the
application from the Dock (by relocating it on the Dock, or selecting
'Keep in Dock'), the next time it is launched from the Doc, it will
crash. This is because the actual FLTK application is launched instead
of the launch script, which presumably must run or else it can't find
its configuration files.
(In this situation, the _CFURLString =
/Applications/Tunneler.app/Contents/MacOS/data/metropipe_tunneler)
I've been messing around with the Info.plist file, but I think the
problem will require more tweaking than that.
The questions that I have at this moment, that if answered might lead to
a solution are:
1) Is using a shell script to launch a Carbon app an acceptable method
of launching a bundled application?
2) If not, I assume that the metropipe_tunneler FLTK carbon application
itself needs to be the value of the CFBundleExecutable plist item, not
the Tunneler.sh shell script. Is this the case?
3) Given that the preparation in the Tunneler.sh script must be
performed, what is the best way to do it if the script cannot be called
as the CFBundleExecutable?
I would greatly appreciate any help that can be offered. If the work
required to get this done extends beyond what is appropriate to expect
from a free email list, then I would be interested in paying for a
solution as well, pehaps via Google Answers.
Regards,
Josh Ellison
