这是我的第一个C程序,我在他们的网站上使用这个示例libcurl代码:
#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, "https://google.com/");
#ifdef SKIP_PEER_VERIFICATION
/*
* If you want to connect to a site who isn't using a certificate that is
* signed by one of the certs in the CA bundle you have, you can skip the
* verification of the server's certificate. This makes the connection
* A LOT LESS SECURE.
*
* If you have a CA cert for the server stored someplace else than in the
* default bundle, then the CURLOPT_CAPATH option might come handy for
* you.
*/
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
#endif
#ifdef SKIP_HOSTNAME_VERFICATION
/*
* If the site you're connecting to uses a different host name that what
* they have mentioned in their server certificate's commonName (or
* subjectAltName) fields, libcurl will refuse to connect. You can skip
* this check, but this will make the connection less secure.
*/
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);
#endif
res = curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
}
return 0;
}
所以在xcode中我创建了一个名为curl的“组”并添加了curl目录中的所有文件:
现在我收到这些Build错误:
我做错了什么?任何建议都会有所帮助,谢谢!

Mac OS X附带了libcurl的副本,因此您的应用程序不需要自己的副本。
您没有提到您正在使用的Xcode版本。以下内容适用于3.2,但可能无法在4中使用。
要使用系统提供的libcurl版本,请转到Project
,然后转到Add To Project
。在出现的对话框中,键入/usr/lib
并按Enter键。在文件列表中找到libcurl.dylib
,然后点击Add
。

对于Xcode 4.5:
现在,当你构建它时,它应该能够链接到库。

对于XCode 7,只需右键单击要放入lib的项目或组,然后选择Add Files to "Project Name"...
,最后找到libcurl.dylib
目录中的/usr/lib
。
