You need to check in your system where is the library installed.

In my system is in /usr/lib

Maybe you have it in /usr/local/lib

It's seems that ld can't find the library in your system paths.

Try to add the path where you have the libcurl.so.4 to your LD_LIBRARY_PATH variable, like this:

export LD_LIBRARY_PATH=/usr/local/lib

substitute the path with the one where libcurl is installed.

This is a temporary (session) solution. You will need to change system configuration as root to make it permanent.

Thanks for your answers, i did it and it compiled but when i try to execute with ./progam I have this error:

Error while loading shared libraries: libcurl.so.4: cannot shared object file: no such file or directory

Do I need to install another library??

You need also to link to the library.

If the library is installed in the system you just need to have a -lcurl in your gcc command line like this:

gcc -lcurl -o program program.c

You also need to change void to int as main return value.

Oggetto: curl_easy_init not defined

Hello!

Im a newbie in C programming, i have to program an application to use it as a daemon which sends periodically a http request to the server.

Im write this:

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#include <curl/curl.h>

void main(){

 CURL *curl;

 char *url;

url="http://192.168.0.63:80/admin/serverreport.cgi";

 curl = curl_easy_init();

 if(curl) {

   curl_easy_setopt(curl,CURLOPT_URL, url);

   curl_easy_setopt(curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

   curl_easy_setopt(curl, CURLOPT_USERPWD, "user:password");

   curl_easy_cleanup(curl);

 };

}

But when I try to compile, gcc -o program program.c,

The compiler says that

(.text+0x12) Reference to curl_easy_init not defined

(.text+0x36) Reference to curl_easy_setopt not defined

(.text+0x41) Reference to curl_easy_setopt not defined

(.text+0x64) Reference to curl_easy_setopt not defined

(.text+0x92) Reference to curl_easy_cleanup not defined

Thanks for your help!
