genisoimage not available (MacOS 11.3) about ghidra-app-bundle HOT 7 CLOSED

I've pushed up a version that uses hdiutil to create the dmg. hdiutil is bundled with macOS and so you shouldn't need to install anything with brew.

Please try this new version.

from ghidra-app-bundle.

It doesn't seem to catch the exception (not working, still):

Oh apologies, I see the issue. There's a missing quotation mark.

I've just pushed a new commit. Please try again, this time it should work.

from ghidra-app-bundle.

Now it builds the dmg. However, the app bounces once and quits. I have tried code signing with no change. Console is giving me this:
May 5 14:25:48 MacBook-Air com.apple.xpc.launchd[1]: Coalition Cache Hit: app<application.gov.nsa.ghidra.13496623.13496627(503)> [19156]

Note: the build I did using my suggestion in the OP works.
Also possibly related or not:
bash-3.2$ ./update.py --dmg
[!] Neither path nor url were specified!

Can you please try running the Ghidra.app/Contents/MacOS/ghidra script directly from the terminal after building and extracting? The behaviour you described is what happens when the script can't find your JDK. You should at least get some output to help diagnose the issue.

Curious that your build with mkisofs works... Can you run the script directly as I described above and compare the output? It might also be worthwhile trying the --tar option.

Please note with the codesigning: I have placed the Ghidra install (which contains executables) into Resources which is a "non-code place". This will surely lead to an invalid bundle sig if you sign with --deep.

Sorry, my bad. As I had my successfully built app, I saved the latest as Ghidra 2.app. That screws up the load script as it is hardwired to expect just Ghidra.app. Working successfully once renamed.
However, the ./update.py --dmg does not work without a url (eg as in your second example).
