MinGW 上的 GCC：libcurl 中不支持或禁用协议“https”

Question

I'm using MinGW on Windows 10 Professional.

I installed libcurl with the following commands:

$ git clone https://github.com/curl/curl
$ cd curl
$ ./buildconf.bat
$ mingw32-make mingw32
$ cp lib/libcurl.a /c/MinGW/lib
$ cp -r include/curl/ /c/MinGW/include

Then I wrote the following toy C++ program to test it:

#include <iostream>
#include <curl/curl.h>

int main(void) {
    CURL *curl;
    curl_global_init(CURL_GLOBAL_ALL);
    curl = curl_easy_init();
    curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
    curl_easy_setopt(curl, CURLOPT_URL, "https://api.ecs.rocks/v0/util/removeMessageHeader");
    curl_easy_perform(curl);
    curl_free(curl);
    return 0;
}

Then I compiled it with the following command:

$ g++ main.cpp -o curltest -m32 -DCURL_STATICLIB -lcurl -lws2_32 -lwldap32 -lwsock32 -lwinmm

Everything looks good at this point. My pwd now contains a new file named curltest.exe .

I try running it:

$ ./curltest.exe

And I get this output:

* Protocol "https" not supported or disabled in libcurl
* Closing connection -1

What have I done wrong? How do I enable support for HTTPS in libcurl built from source on MinGW?

You have built libcurl without any TLS library. I suggest you having a look at the official curl guide on how to build curl on MingW32. It also explains what to do to enable TLS.
