Hello,
In the past I've done a mediocre amount of PackageMaker
installation packages, strictly through the GUI interface.
Typically it was only when I needed a KEXT installation, as most
other products could handle manual installation procedures. I've
changed jobs and now I'm the resident "Mac Guy" and have been
prompted with a more complicated installation request. I've read
over the Package Maker docs, and the Software Distribution docs,
but I'm still a bit confused on a few issues.
First I'll explain my goal for the installer.
•The installer needs to first determine the system version being
installed onto and make a logical branch for various components
based on that. I've been able to easily replicate this by selecting
the component title, not item, and setting the specific
Requirements. After the installer makes the first logical branch,
the end user is to be displayed a message at which point they can
either continue with the installation, or quit (long winded
explanation why). This message is NOT needed on the other logical
branch. Is there anyway for the UI of the installer to be dynamic
with respect to Requirements?
The answer might be yes.
This would require writing an Installer Plugin (if your package
format is FLAT, you can't do that).
According to the APIs, you can know whether a choice will be
installed or not.
- [InstallerState choiceDictionaryForIdentifier:]
InstallerState_Choice_Installed
So you can check your branch this way in the [ willEnterPane:] method
of your InstallerPane subclass.
Then you can either display the explanation and the quit button or
just force Installer.app to go to the next pane (You would need to
take into account the Go Back case for the next pane).
•Some of the installation content are packages from a third party.
Only the issue is these packages contain multiple items to install,
such as Frameworks and KEXTs. How can I adjust my Distribution
Package in PackageMaker GUI (or through command line) to properly
install these packages? When I add them as an item in PackageMaker
they set their Installation Location to /. In previous PM I was
used to the notion you had to create a file structure which
mirrored the installation locations, does current PackageMaker not
notice this and adjust it's installation locations accordingly?
If you're not using a flat package, it should be possible to make a
reference to an existing package.
Other Issues:
•I've noticed some weird "radial" behavior on the customized
install screen. If say I have 2 packages and PDF as content to be
installed, and I try to select / deselect various items I'm getting
some toggling between the content. What is causing this and how/can
I get it go away?
Not sure what you mean here.
