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 algún tipo

Configuré mis otras banderas de vinculador en -lxml2

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

pero aún obtengo un montón de símbolos indefinidos cuando intento compilar. Los errores a continuación son el resultado de intentar compilar TouchXML.
