Vcomponents in Mach-O Package

[Dave Addey]

Hi Ruslan,

No, I'd already read that thread and tried everything it suggests.  The
problem is that when you compile as a Mach-O application in REALbasic, the
application is *already* a bundled .app folder, with the structure in place.
So, AppBundler can't do anything with it.

I think the Mach-O term for it is a Package rather than a Bundle, but the
structure is essentially the same.

If you compile a REALbasic project as a Mach-O app, and then right-click on
the application in the Finder, you should have an option to "Show Package
Contents".  This opens the .app as a folder, and lets you look inside.

I'm pretty comfortable with packages.  I already have an applescript that
will copy a .dylib file (for using HID input devices) into a
/Contents/Frameworks/ folder once REALbasic has built the Mach-O
application.

To be honest, having worked with the "package" format, I wouldn't use
AppBundler anyway, excellent as it is.  I just do the file copying myself
after I have comiled the Mach-O application.

Here's a page from the Apple site, which talks about loading code at runtime
for Mach-O:

http://developer.apple.com/documentation/DeveloperTools/Conceptual/MachOTopi
cs/Articles/loading_code.html

My guess is that the V4RB plugin is looking for the files it needs in the
executable application's folder (@executable_path) and looking in CFMSupport
if it can't find them there first.  What it *could* do instead is to:

* Look in the application bundle's /Contents/Frameworks/ folder first
* Look in the application's folder (as it does at the moment)
* Look in the CFMSupport folder (as it does at the moment)

My guess is that it isn't doing this first step, which is why it never finds
my files.

This would mean that we could copy the files inside the Mach-O Package if we
wanted, and then the plugin code would check each location in turn at
runtime until it found the files it needs.

Hope this helps!

Dave.
