Porting PackageMaker command line build installer to pkgbuild

Unfortunately the answer to this question wasn't exactly what I was looking for. I couldn't figure out how to eliminate PackageMaker from the process. However there is a solution that includes pkgutil along with PackageMaker to create an installer with custom welcome message, license and background image entirely on the command line. The PackageMaker GUI is NOT required. The steps are as follows:

1. Run the packagemaker command line executable on the special directory structure. This directory structure reflects the Mac file system. Read more in the old but reliable "PackageMaker How-to" tutorial.
2. Run pkgutil (pkgutil --expand) to extract the package contents
3. Take a look at the contents and identify what you want to alter. Some options are the welcome message, license and background image.
4. Add commands to alter these files via the command line. Review the "Automating Apple's PackageMaker" tutorial for more information. The easiest way is just to run something like this echo '<background file="your_background.png">'.
5. Run pkgutil (pkgutil --flatten) to rebuild the package.

First of all, are you sure that you need an installer? You could put the framework inside the application. The Installer and pkgbuild are a bit flaky, to say the least.

Now to the problem at hand: Relocation has to do with the fact that a user could move the Application from /Applications to say /WorkApplications /PrivateApplications. In your case the Installer probably finds your Application in the build folder and installs it over this one.

I think the Installer uses the Application Bundle Identifier and Spotlight for the relocation, so for testing you could add the build folder to the Spotlight ignore list.

You can define in the Component Property List BundleIsRelocatable. If you really have to install a framework global, this is one bundle where you want to set BundleIsRelocatable to false.

The question you reference has pretty much everything you need to eliminate Package Maker entirely. One thing I added is to use sed after the productbuild --synthesize ... invocation to insert lines into the distribution file. For example, here are some Terminal commands I use once I've already built the component package:

productbuild --synthesize --package "components/SubPackage.pkg" "distribution.xml"
sed -i "" \
-e '$ i\
\    <title>Installer Title</title>' \
-e '$ i\
\    <background file="background.png" alignment="left" scaling="proportional" />' \
-e '$ i\
\    <welcome file="welcome.rtf" />' \
"distribution.xml"
productbuild --distribution "distribution.xml" --resources "resources/" --package-path "components/" "Installer.pkg"

This avoids having to use pkgutil --expand and pkgutil --flatten to modify the installer.
