creating dmg files about osxcross

osxcross is just a toolchain. What it has to do with creating dmg?

Ha ha. But seriously, yeah. Just create an image formatted ISO or UDF, add .dmg, presto.

The toolchain does not contain Rez and DeRez, and some other tools.
Also simply creating a .dmg file with genisoimage doesn't give you the look and feel of a native mac app bundle including icons and so on.
The goal is to be able to create a shippable product and not just some lose binaries.
Also I specifically said "for future reference" since I thought some people in this particular community might be interested.
A more constructive contribution than simply doubting the need would have been appreciated.

They are not open source.

This doesn't seem to be osxcross goal.

If you are looking for references, creating fancy dmg:

Working with dsstore:

I'm using https://github.com/andreas56/libdmg-hfsplus with buildbot. While you can technically create them with genisoimage, there are two drawbacks. Can't set extended attributes (setting background image, or creating symlinks), all files will be read only and the permissions carry over when copying off the dmg. So, when the user copies the application to their desktop and tries to delete it later, Finder will popup asking for permission (password).

$ OUTSIZE=$(du -S ./disklayout/) # get the output disk size
$ dd if=/dev/zero of=temp.dmg bs=1124 count=${OUTSIZE}
$ mkfs.hfsplus -v "Project Name" temp.dmg
$ hfsplus temp.dmg addall ./disklayout/
$ hfsplus temp.dmg symlink " " /Applications
$ dmg dmg temp.dmg compressed.dmg

This is essentially what Firefox will be using soon. They are going to be cross compiling OSX on linux very soon.

1. As @noscript's answers implies, what makes "fancy" .dmgs fancy is completely independent of how the disk image is formatted. Likewise, tools like Rez and DeRez are very much deprecated; this information is now stored in files like .DS_Store and .background, which you can create yourself with on another platform with some ingenuity. But I'd agree this really isn't an issue for osxcross, any more than the reverse would be an issue for, say, crosstools-ng.
2. I wouldn't say "node-appdmg" is close to cross-platform so long as it still calls utilities like hdiutil...
