iPhone libxml2 simboli non definiti (con gdata, kissxml, touchxml, ecc.)

Question

Sto provando a utilizzare uno qualsiasi dei parser XML di terze parti basati su libxml, ma non posso perché penso di avere un problema libxml2 di alcuni sorta

ho impostato il mio altre bandiere linker per -lxml2

e percorsi di ricerca intestazione per /usr/include/libxml2

ma ho ancora un sacco di simboli non definiti quando provo a compilare. Gli errori seguenti sono il risultato del tentativo di compilare TouchXML.

Ho avuto lo stesso problema. È andato via quando ho collegato il binario con la libreria.

Vai a Target -> Crea Fasi -> Collegamento binario con libreria, fare clic sul segno più e aggiungere "libxml2.dylib"
