curl.h没有这样的文件或目录

我安装了curl这个命令(我使用的是Ubuntu):

sudo apt-get install curl

当我使用g++ test.cpp

测试简单程序时
#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");

    /* 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;
}

g++告诉我:

fatal error: curl/curl.h: No such file or directory
compilation terminated.

任何人都可以帮助我吗?

sudo apt-get install curl-devel

sudo apt-get install libcurl-dev

(将安装默认备选方案)

OR

sudo apt-get install libcurl4-openssl-dev

(OpenSSL变体)

OR

sudo apt-get install libcurl4-gnutls-dev

(gnutls变种)

那些使用centos并偶然发现这篇文章的人:

 $ yum install curl-devel

在执行你的程序&#34; example.cpp&#34;时,链接到curl外部lib:

 $ g++ example.cpp -lcurl -o example
 $ ./example

 -o example : creates executable example
 the next line runs example

而不是下载curl,而不是libcurl。

curl只是应用程序,libcurl是您的C ++程序所需要的

是的,请按照上面的说明下载curl-devel。 也不要忘记链接到lib curl:

-L/path/of/curl/lib/libcurl.a (g++)

安装-apt-get install libcurl4-openssl-dev没有帮助。

luarocks install Lua-cURL
Installing https://luarocks.org/lua-curl-0.3.9-1.src.rock

Error: Could not find header file for CURL
  No file curl/curl.h in /usr/local/include
  No file curl/curl.h in /usr/include
You may have to install CURL in your system and/or pass CURL_DIR or CURL_INCDIR to the luarocks command.
Example: luarocks install lua-curl CURL_DIR=/usr/local

我什至尝试过,但还是不行-

luarocks install Lua-cURL --server=https://luarocks.org/dev CURL_DIR=/usr/bin/curl

如果在安装curl-dev luarocks之后看不到标题,则

find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h

luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/
