Question

我刚开始使用C ++，但是我在使用libcurl编译Windows / Cygwin中的代码时遇到了问题。我相信我正确安装了库，但是当我尝试编译这段代码时：

#include <stdio.h>
#include <curl/curl.h>

int main(void)
{
CURL *curl;
CURLcode res;

curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* example.com is redirected, so we tell libcurl to follow redirection */ 
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

/* Perform the request, res will get the return code */ 
res = curl_easy_perform(curl);
/* Check for errors */ 
if(res != CURLE_OK)
fprintf(stderr, "curl_easy_perform() failed: %s\n",
curl_easy_strerror(res));

/* always cleanup */ 
curl_easy_cleanup(curl);
}
return 0;
}

我收到以下错误：

回答这个问题。

对于resumate：通过在“属性”选项卡中包含Curl库，您可以成功避免错误。
