आईफोन libxml2 अपरिभाषित प्रतीकों (gdata, kissxml, touchxml, आदि के साथ)

Question

मैं किसी भी libxml आधारित तृतीय पक्ष XML पार्सर्स का उपयोग करने का प्रयास कर रहा हूं, लेकिन मुझे नहीं लगता क्योंकि मुझे लगता है कि मेरे पास libxml2 समस्या है तरह

मैं अपने अन्य लिंकर झंडे -lxml2

को हैडर खोज पथ करने के लिए सेट और/usr// libxml2

लेकिन जब मैं संकलन करने की कोशिश मैं अभी भी अपरिभाषित प्रतीकों में से एक टन मिल शामिल हैं। नीचे दी गई त्रुटियां TouchXML को संकलित करने का प्रयास करने का परिणाम हैं।

जाओ लक्ष्य बनाने के लिए -> निर्माण के चरण -> लाइब्रेरी के साथ लिंक बाइनरी, "libxml2.dylib"
