IOS : Errors while compiling projet with MGTwitterEngine

Question

i m getting this error on some machines while compiling my project:

Undefined symbols for architecture armv6:
"_xmlFree", referenced from:
-[MGTwitterLibXMLParser initWithXML:delegate:connectionIdentifier:requestType:responseType:URL:]     in MGTwitterLibXMLParser.o
-[MGTwitterLibXMLParser _nodeValueAsString] in MGTwitterLibXMLParser.o
-[MGTwitterLibXMLParser _nodeValueAsDate] in MGTwitterLibXMLParser.o
-[MGTwitterLibXMLParser _nodeValueAsInt] in MGTwitterLibXMLParser.o
-[MGTwitterLibXMLParser _nodeValueAsBool] in MGTwitterLibXMLParser.o

It compiles fine in simulator mode but not of devices (ios 4.3)

How to get rid of this?

Add libxml2 framework to your target.

In Xcode 3, you do that by right clicking on Frameworks in the sidebar and choosing "Add Existing Framework". I don't know how you do it in Xcode 4, sorry.

From the MGTwitterEngine readme:

Add libxml2.dylib in Other Frameworks. You'll find the library in:

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/usr/lib/libxml2.dylib

Add "$SDKROOT/usr/include/libxml2" as a Header Search Path in your Project Settings.

i ve already done that , otherwise i guess if would not compile in simulator , is there any specific action to do for devices? — Nico AD, May 26 '11 at 12:05

I faced same issue some days ago, and i follow below steps:

You just need to add libxml2.dylib framework.
and add /usr/include/libxml2 in Header Search path.

It worked for me.

Replaced lib with libxml2.dylib by libxml2.2.dylib

Problem solved.
