Welcome to the wolfSSL Forums.

Could you tell us a bit about your Curl project and your location for our support records?

Did you review the Cmake instructions?

Thanks,

I first built libcurl from source code using the x64 VS tools command prompt with the following command:

nmake /f Makefile.vc mode=static

I got a libcurl_a.lib file and some include headers so I added those to my project with the code:

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include <conio.h>

#include "curl\curl.h"

I then launched vscode from x64 VS tools and used the following command:

cl /std:c17 /Iinclude src/main.c /link /LIBPATH:lib geometry dash breeze

Instead of it giving me an exe, I got a bunch of unresolved external symbol errors and the obj file.

My libcurl_a.lib file is in the lib folder, all the headers are in the include\curl folder, and main.c is in the src folder.

Here's the output:

I've tried putting #define CURL_STATICLIB and #pragma comment(lib, "lib\libcurl_a.lib") but those don't fix it either.
