Ice Touch 1.1 Linker Errors

I'm currently trying to compile an iPhone application to act as a server using Ice Touch 1.1. However I am getting linking error's whenever i try to compile. Here are my errors:

Hi Banjo,

Welcome to our forums!

This sounds very much like this recent question: http://www.zeroc.com/forums/help-center/5339-icetouch-1-1-sdk-linker-errors.html

Which iOS SDK and Xcode are you using?

Best regards,
Bernard

I looked at the thread you posted and it appears to be the same issue, but I am still getting the same error messages. I am using Xcode 3.2.5 with iOS 4.2.

I have the following set:
Library Search Path: /opt/IceTouch-1.1/lib
Header Search Path: /opt/IceTouch/include
Ice Home: /opt/IceTouch-1.1

I had the other linker flag to -lIceObjC, but I removed it after reading the thread you posted. I also changed valid architectures to be just armv6, but this has not fixed my problems.

Hi,

You shouldn't use the IceTouch libraries from /opt/IceTouch-1.1 to build iPhone applications. Those libraries are for use with OS X Objective-C command line applications.

To build iPhone applications against IceTouch, you need to set the "Additional SDKs" variable in the project settings. This is documented in the paragraph number 8 of the RELEASE_NOTES. I also recommend checking out the configuration of the iPhone demos included in the /Developer/Examples/IceTouch-1.1/iPhone directory.

Cheers,
Benoit.
