How to build a static binary with libcurl?
Good day.
There is the following code:
#include <stdio.h>
#include <curl/curl.h>
int main(void){
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl == NULL)
return 0;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/getAccessAttributes?id=1");
res = curl_easy_perform(curl);
if(res != CURLE_OK) {
fprintf(stderr, "Error: %s\n", curl_easy_strerror(res));
return 0;
}
curl_easy_cleanup(curl);
return 0;
}
