‘strcmp’ không được khai báo trong phạm vi này

Question

Tôi đang làm việc để xây dựng chuỗi công cụ ios với số tutorial này. Khi tôi chạy lệnh, hãy tạo ENABLE_OPTIMIZED = 1 Tôi nhận được kết quả này.

Tôi không chắc phải làm gì với điều này và googling của tôi không giúp được gì nhiều.

Answer 1

chức năng strcmp được khai báo trong string.h cố gắng đưa

#include <string.h> 

trong DynamicLibrary.cpp và stderr được defained trong stdio.h nên đặt quá

#include <stdio.h> 

Thỉnh thoảng tôi tìm thấy mã nguồn mở với các tệp tiêu đề bị thiếu.
