編譯libxml2的出現 「Error：的 '提示' 存儲大小是不知道」

Question

我下載的libxml2 2.9.4在here，當我./configure; make，我得到以下錯誤：

nanohttp.c: In function ‘xmlNanoHTTPConnectHost’: 
nanohttp.c:1073:18: error: storage size of ‘hints’ isn’t known 
    struct addrinfo hints, *res, *result; 
       ^

我嘗試2.9.2版本2.9.3和我得到同樣的錯誤，如何編譯libxml2的成功呢？

Answer 1

我找到了解決辦法：

在nanohttp.c

，錯誤行：

#if defined(HAVE_GETADDRINFO) && (defined(SUPPORT_IP6) || defined(_WIN32)) 
    { 
    int status; 
    struct addrinfo hints, *res, *result; 

這樣我就可以禁用IPv6以不編譯這個代碼塊中。我嘗試下面的代碼將工作：

./configure --enable-ipv6=no LIBS="-lpthread"; make 

我發現 「--enable-IPv6的」 在 「的libxml2-SRC /配置」

Answer 2

對於使用 「的getaddrinfo」 你必須使用POSIX。 對於清潔C，使用gcc flag -std=gnu11或-std=gnu99代替с11/с99。 檢查POSIX您可以使用此代碼：

#ifdef __USE_POSIX 
    #warning POSIX compatible 
#else 
    #warning no support POSIX 
#endif
