Símbolos no definidos de iPhone libxml2 (con gdata, kissxml, touchxml, etc.)

Question

Estoy tratando de usar cualquiera de los analizadores XML de terceros basados ​​en libxml, pero no puedo porque creo que tengo un problema libxml2 de algunos Ordenar

puse mis otras banderas de engarce a -lxml2

y rutas de búsqueda de cabecera a /usr/include/libxml2

pero aún así obtener una tonelada de símbolos no definidos cuando intento compilar. Los siguientes errores son el resultado de tratar de compilar TouchXML.

Tuve este mismo problema. Se fue cuando conecté el binario con la biblioteca.

Ir a Target -> Construir Fases -> Enlace binario con Biblioteca, haga clic en el signo más y añadir "libxml2.dylib"
