c - GCC 无法编译 libcurl 示例 : ‘CURLINFO_TOTAL_TIME_T’ undeclared

Question

我正在尝试编译libcurl的示例代码fileupload.c在 Ubuntu 18.04 LTS 上使用 GCC 时，出现以下错误:

~ gcc fileupload.c 
In file included from /usr/include/x86_64-linux-gnu/curl/curl.h:2738:0,
                 from fileupload.c:27:
fileupload.c: In function ‘main’:
fileupload.c:76:31: error: ‘CURLINFO_TOTAL_TIME_T’ undeclared (first use in this function); did you mean ‘CURLINFO_TOTAL_TIME’?
       curl_easy_getinfo(curl, CURLINFO_TOTAL_TIME_T, &total_time);
                               ^
fileupload.c:76:31: note: each undeclared identifier is reported only once for each function it appears in

作为 libcurl，我安装了 Ubuntu 的 libcurl4-openssl-dev 软件包。谁能告诉我为什么 CURLINFO_TOTAL_TIME_T 未声明，尽管它应该是 part of the library ？

这是示例代码:
