'strcmp' इस दायरे में घोषित नहीं किया गया था

Question

मैं इस tutorial के साथ आईओएस टूलचेन बनाने पर काम कर रहा हूं। जब मैं कमांड चलाता हूं ENABLE_OPTIMIZED = 1 मुझे यह आउटपुट मिलता है।

मुझे यकीन नहीं है कि इस बारे में क्या करना है और मेरे गुगल ने बहुत मदद नहीं की है।

Answer 1

strcmp समारोह string.h में घोषित किया जाता है

#include <string.h> 

DynamicLibrary.cpp में

डाल करने के लिए कोशिश करते हैं और stderr stdio.h में defained है, ताकि भी

#include <stdio.h> 

समय-समय मैं करने के लिए रखा अनुपलब्ध हेडर फ़ाइलों के साथ ओपन सोर्स कोड भी मिला।
