Transitioning a GLX based Mac OS X app to Levure - problems with preferences

[MartinKoob]

Hi Trevor

I have a Mac OS X application that is based on the GLX application framework that I need to transition to LC 9. (I am still using the LC 6.7.3 IDE for development of this app.)

Complicating this transition is the fact that I have been using Monte’s lcVCS plugin for version control. (I use SourceTree and BitBucket.) I want to move the application to using Levure so I can continue using source control.

I can open my app in LC 8.1.9 Stable with a few tweaks but I can’t use that for development because of issues with the transition from using the mergAV camera to the new cameraControl. I need feature improvements in LC 9 to the cameraControl as well as some other new features.

I have taken stabs at this over the last year at trying to convert my application to LC 8.1.x and now 9.0 but have run into a road block there.

When I try to open the application in the IDE with LC 9.0 I get an error on launching it.

“An error occurred while loading the application preferences: unable to load all externals (preferences library not found.)"

I tracked this down and found it originates in

Stack: glxApplicationFramework Handler: _loadExternals

The preferences.bundle external is in the components/externals folder but it seems it can’t load the external in LC 9.0 even though it can load it in LC 8.1.9.

I looked through my application for the calls that are made to the GLX framwork and there are only these: glxAppSetProp, glxAppGetProp, glxAppSetPref, glxAppGetPref, glxapp_savePrefs, glxApp_updateAvailable

So externals are pretty much all that I use in the GLX application.

I was wondering if there is a way to get around the load preferences external error for now so I can have the GLX based application running in LC 9.0 IDE to be able to I work on transitioning the application to Levure?

If that is not the right approach what do you suggest?

Thanks.

@MartinKoob LC 9 opens as 64-bit by default on macOS. The preferences external is 32-bit. In the file info panel for the LC 9 app you can specify that it should open as 32-bit. Do that and then try again.

I'm working on creating extensions using LCB for all of the Objective-C code I use. Updating the preferences helper in Levure to use an extension rather than an external is on the list. Once that is done the prefs helper will work in 64-bit.

@trevordevore Thanks for the quick reply. LC 9.0 running in 32bit mode is able to load the preferences external and open my app.

Looking forward to the prefs helper.

@MartinKoob You're welcome. I'm glad it is working for you now.
