Hi Tharindu,

This message

ld warning: in /Users/tharindu/Documents/XMPPiPhone/libidn/iphoneos/
libidn.a, missing required architecture arm in file
  

indicates you're linking against the iPhone version of libidn when compiling for the simulator.

Double-check step 5 from here: http://code.google.com/p/xmppframework/wiki/iPhone

Make sure you're using "$(SRCROOT)/libidn/${PLATFORM_NAME}"

This way, when compiling for the simulator, your compiler will automatically use:
/Users/tharindu/Documents/XMPPiPhone/libidn/iphonesimulator/libidn.a

Hi
Thanks, I tried to follow step 5, but i could not successfully make it, how ever in the end I have hard coded the right version when I compile for device or simulator, then it worked finally
Thanks again.

Hi, i am facing the same problem.

May you show me how u hard coded the right version?

[Robbie Hanson]

Did you follow the instructions from here:
http://code.google.com/p/xmppframework/wiki/iPhone

Make sure you follow step 5 very carefully.

Hi,

I have follow the step 5 very carefully. I am using the libidn from
the svn.

My project folder is "Messenger", then

/Messenger/libidn/iphoneos/libidn.a
/Messenger/libidn/iphonesimulator/libidn.a

and i add "$(SRCROOT)/libidn/${PLATFORM_NAME}" to the Library search
paths
and i add -lxml2 and -lidn to the other linker flag

Check to see what the ld command is doing when you're compiling:

This is the path "-L/Users/hanyighost/Workspace/Projects/XMPP-

Thanks

That's very odd. Would it be possible for you to send me the
project? Or does the project already include a bunch of your own
private code?

The project after i zip is still more than 4mb, so i provide a
download link for my project.

Thanks.

Hi,
"$(SRCROOT)/libidn/${PLATFORM_NAME}"
this did not work for me, then I have hard coded the path and put the correct libidn.a file there manually, when ever bulding to device or simulator.
Have a try. some times this might solve it. If its a linking issue. I am not sure.

Hi,
Just hard code the linking path, it just worked in my machine. :) I tested with your code.

You have them backwards. You have the iphone libidn file in the
simulator folder, and vice-versa.
