Linking issues on Ice Touch

[ekfliu]

I attempted to compile an Ice Project in xcode but resulted in library not found for -lIce. I already put /opt/IceTouch-1.0/lib on the Library Search Paths but that did not resolved the problem. Anyone has idea on what is the issue?

The Objective-C Ice library is called IceObjC, not Ice. If you are a building a Cocoa, or iPhone application then you should use the IceTouch Xcode SDK (as documented in the RELEASE_NOTES file accompanying the distribution). In this case, you don't need to add any library to your linker options.

I highly recommend that you watch one of my screencasts which shows precisely how to setup an Xcode project for each of the project types for Xcode.

I have reinstall the IceTouch 1.0 Package and follow the video. I was able to build however when attempting to run on the iphone simulator it crashed with the following error.

Dyld Error Message:
Library not loaded: @executable_path/libIceObjC.dylib
Referenced from: blah blah
Reason: image not found

Looks like it cannot find the dylib file, do I need to set the library search path? That was not done in the video....

Hi,

You need to copy the IceObjC shared library to the application bundle for the simulator. This is documented in the RELEASE_NOTES, here's the relevant part:

For iPhone Simulator applications, the dynamically linked Ice libraries
must be copied into the application directory. For our iPhone demos,
this is done in the Xcode project with a post-build script as follows:

if [ $PLATFORM_NAME = iphonesimulator ]; then
  cp $ADDITIONAL_SDKS/usr/local/lib/*.dylib $BUILT_PRODUCTS_DIR/$CONTENTS_FOLDER_PATH
fi

How to add this post build script to the Xcode project is shown in the IceTouch Intro screencast (in the last quarter of the screencast).

Cheers,
Benoit.
