xcode: symbols missing when linking

niconico Member Nico MuellerOrganization: SiemensProject: client/server-based navigation in a car, remote
even after copying all of your hello-examples settings, setting the build-script (the one for the simulator-dynamic-libraries), i get the following error on xcode.
your example compiles without problems, so the plugin should be working.

the nav.ice is valid, it is directly from the developer, i am doing the interface to.

so, do you have any idea, what it could be ?

    as your wish was, i updated the information and you wanted to give me some help ?

    Hi,

    Can you confirm that you installed Ice Touch 1.0 using the installer?

    It sounds like the "Additional SDKs" setting for your target is missing (I don't see the -lIceObjC library added to the linker flags).

    Can you check that the "Additional SDKs" field is set to "/Developer/SDKs/IceTouch-1.0/$(PLATFORM_NAME).sdk" in your target properties? To access the target properties, in the "Targets" group, right click on the your target and select "Get Info".

    How to setup the project is also documented in the first few minutes of the Ice Touch introduction webcast here. You'll also find information on the setup of the project in the RELEASE_NOTES file installed in /Developer/Documentation/IceTouch-1.0/RELEASE_NOTES

    Cheers,
    Benoit.

    yes..

    it was missing, but adding didn't help either..

    some comment on your webcasts:
    it is hard to see a difference between I and l in the font used. on the other hand after some webcasts i believe, that you do different settings in different webcasts, so figuring out the right settings is not so easy
    You'll also find information on the setup of the project in the RELEASE_NOTES file installed in /Developer/Documentation/IceTouch-1.0/RELEASE_NOTES

    Cheers,
    Benoit.


    after adding and doing the things you wanted me to do, the output looks quiet similar then before. no changes.
    i'm just wondering, why your example works and mine not.

    Hi,

    Hmm, did you set it for "All Configurations"? I can't think of any other settings which would be missing :(

    Btw, why does -L/opt/Ice-3.4/lib shows up in the linker command? Did you add it to the "Other Linker Flags" settings? This shouldn't be necessary.

    Can you specify which versions of Xcode and the iPhone SDK you are using?

    The best way to figure this out would be to post your sample project here in a zip file (or if you prefer you can also send it to me directly at [email protected]). I'll be happy to take a look at it to try to find what is causing this linker error.

    Cheers,
    Benoit.
