Build failure on Catalina

[jasonshanks]

HI – I noticed after running Catalina Beta that Zoom isn't 64bit. Tried to build project with most recent Xcode failed. Is getting this working on 64-bit going to be a lot more more?

Thanks for keeping this alive over the years!!

I've pushed my latest version that compiles with Mojave. That's all it does at the moment: there's some kind of incompatibility with the newer framework version that causes it to crash on startup, combined with something that's causing XCode's debugger to fail to attach properly, which is getting in the way of working out what's going wrong.

Note that you can find a version I compiled a few years ago that should have 64-bit support over at https://logicalshift.io/zoom/Zoom-20150906.zip

Nope.
Doesn’t.

Hope this helps:

Any news on this? I tried compiling the code but it fails due to not being able to find code in the babel project that was installed in the directory above the source code for zoom. Installing the babel transpiler does not help.

[Logicalshift]

I think the source code for babel that can be retrieved from http://babel.ifarchive.org still works with the current version of Zoom: the version I have is 0.2b from 2006.

I've got it compiling and it seems to be working (still on Mojave here) but the Glulx plugin isn't working at the moment: it's the cause of the crashes I think - when compiled with a more modern library it returns a nil value for the principal class: the errors aren't that helpful but it looks like something is linking both the client and the view (which then fails to load as the communication classes are defined in both libraries)

[cocranfill]

Okay. That version of babel works. When setting a breakpoint in the init method of ZoomAppDelegate.m, I get the following dialogs:

For security reasons, updates to Zoom need to be served over HTTPS and/or signed with an EdDSA key. See https://sparkle-project.org/documentation/ for more information.

In looking at the pList, I see that SUFeedURL is http, not https, and the URL does not exist on logicalshift.co.uk; I'm assuming it would only exist if an update were available. Same with ZoomPluginFeedTestURL.

When accessing ZoomPluginFeedURL, though, the following error appears:

This page contains the following errors:

Has anyone successfully compiled in Catalina?

[cocranfill]

Yes. I submitted my code changes that enabled me to get Zoom compiled under Catalina. Chad Cranfill

[Logicalshift]

It's building for me (it seems there are some circular dependencies that upset the latest version of XCode: I've made some tweaks that might fix this). Zoom's definitely a bit tricky to build as it's a rather old project: the ZoomServer target in particular is of a kind that can only be created in Project Builder!

Not sure what's going on with Catalina at the moment: it's crashing with a null dereference without generating any useful log messages or stack traces. This also happened on Mojave and was to do with the dynamic loading of the various libraries (though it was actually fixable there): see 8e8f093 - I don't think it's getting that far now, but the nature of crash makes it rather hard to debug.

[Logicalshift]

(Just for extra fun: the similar bug in Mojave disrupts the debuggers ability to reliably set breakpoints, presumably due to the crash occurring while loading executable code)

I can't see a PR or branch, nor a fork under your account. @cocranfill

[Logicalshift]

In the meantime, I've made some progress and the latest version will actually run - somewhat badly and only with the Z-Machine interpreter.

There's a bunch of graphical glitches with the iFiction window to be worked through. The old plugin code seems to break something on Catalina and was responsible for the debugger failing, so it's been replaced by a no-op - I think the right thing to do there is to load everything directly and ditch the dynamic loading. There's another graphical glitch in the main game window: no editing cursor.

The crash was due to an invalid operation in an image drawing instruction: it's in an animation so non-critical and I've commented it out for now, not sure if it'll be noticeable if it's just left that way.

[dylanbromby]

@Logicalshift when you say running -- albeit badly -- do you mean on Catalina?

[Logicalshift]

Yes - the current latest version is starting up for me in Catalina: I managed to track down the crash on startup to a (slightly bizarre) crash while rendering an image, which I fixed by just not rendering that image. The problem with debugging turned out to be something to do with the plugin loading system, so I disabled that too.

There's a bunch of calls to obsolete APIs and some warnings about invalid JPEG2000 data that makes no sense at all (I don't think there are any JPEG2000 images in the package), and disabling the plugins means that only the Z-Machine is working, but it's definitely starting up successfully now.
