IceTouch 1.2 with XCode 4.2: missing symbols

[nico]

Hello Guys,

I have a Problem: I made a Project >1 Year ago for iPhone and now, with iOS5, it didn´t work anymore on the devices we used.
So I had to renew all Plugins, so yours (IceTouch 1.0->1.2).
I deleted this plugin-file you mentioned in your scenario, installed 1.2 and tried to run it -> didn´t work, so I reconfigured all. Maybe I made it worse than before, I don´t know, but I hope you can help me.
Also for me, today was the first time to work with Xcode 4.2, before I only worked with 3.*.

Thank you for your help in advance.

My config now:

Hi Nico,

For SDK based builds you don't need to add "/opt/IceTouch-1.2.0/lib" to the "Library Search Paths", you must remove that setting from your configuration to fix the linker errors. /opt/IceTouch-1.2.0/lib contains the ObjC runtime for Mac OS X command line applications.

In "Other Linker Flags", you can remove "-lIceObjC -all_load -ObjC", the Xcode plug-in automatically adds that when required, so you just need "-lGlacier2ObjC" there.

Thank you. I did, what you wrote:
Now, there are at least much less errors:

You need to add "ExternalAccessory.framework" to the Linked Framework and Libraries. That is in the target configuration "Summary > Linked Framework and Libraries".

[nico]

Ok, now it works.
You should mention this (adding the framework) in your release-notes here:
Release Notes - Ice Touch 1.2 - ZeroC
I don´t really understand, why you used this lib, but ok. I thought, this is just for using devices on the connector or bluetooth?

Also I found a second point. With 1.0, you had to have a run script when using the simulator (copying dylibs (?)). This now also gives an error, as you don´t even need it anymore.

Ok, now it works.

Glad is working,

You should mention this (adding the framework) in your release-notes here:
Release Notes - Ice Touch 1.2 - ZeroC

We will update that.

I don´t really understand, why you used this lib, but ok. I thought, this is just for using devices on the connector or bluetooth?

That is required for the IceTouch Accessory transport see:

Release Notes - Ice Touch 1.2 - ZeroC

Also I found a second point. With 1.0, you had to have a run script when using the simulator (copying dylibs (?)). This now also gives an error, as you don´t even need it anymore.

Right, we will add a note about that in "Upgrading your application from Ice Touch 1.0" section of release notes.

[nico]

Thank you.
