When I run exe on windows xp system, it's throwing following exception:

the procedure entry point gettickcount64 could not be located kernel32.dll

My code:

#include <curl/curl.h>
int main()
    CURL *curl;
    CURLcode res;
    curl = curl_easy_init();
    curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "POST");
    curl_easy_setopt(curl, CURLOPT_URL, "xxxxxx");
    struct curl_slist *headers = NULL;
    headers = curl_slist_append(headers, "Content-Type: application/json");
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "{\n\t\"UserName\":\"abc\", \n\t\"Password\":\"xyz\"\n}");
    CURLcode ret = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
    return 0;

So, how to solve that error? Please help. Thanks in advance.

From [MS.Learn]: GetTickCount64 function (Requirements section):

Minimum supported client               Windows Vista [desktop apps | UWP apps]

Alternatives:

  • Don't run it on XP (MS no longer supports it), switch to Vista (or newer) that has the function in Kernel32.dll (this is the most obvious one)

  • If you're using a downloaded cURL (prebuilt) library:

  • Rebuild it using the same tools as your app, and either:

  • #define _WIN32_WINNT 0x0501

  • Pass /D_WIN32_WINNT=0x0501 to the compiler

  • If you're including the cURL sources directly, specify the above compiler flag into your VStudio project ([MS.Learn]: /D (Preprocessor Definitions))

  • While browsing the official download page ([curl]: Releases and Downloads), I found [WinampPlugins]: curl 7.53.1 for Windows.
    So, apparently it's possible to download a binary that is XP compatible. It's an older version, and 032 bit only (064 bit XPs are rare anyway), but it can get you going

    I'm trying to run a game on XP and i get the same error as this post's title. After some search, I realized that there's a file named libcurl.dll in the game's folder, which calls this function. I tried to download this XP compatible binary, but I don't know what to do then. Could you help me? – Kobayashi Aug 16, 2019 at 4:45 @Kobayashi: You need to overwrite (back it up first) the libcurl.dll from your project that calls this function with the one you downloaded. – CristiFati Aug 16, 2019 at 7:16

    I guess you have used pre-built version of libcurl from downloads section of site. I never had this problem myself, but since GetTickCount64 is Windows Vista+ API, it means that they have not compiled library with Windows XP compatibility.

    Try to build library yourself and then see if you program runs with any problem or not.
