I have tried googling, and found no solution to my problem. I’m trying to learn how to use libcurl, a c networking library. I tried compiling a program that was automatically generated from curl, and a few examples i found online but nothing happened. I got no errors or logs, the program stopped “sucessfully” but i get no output. I also cant write to the console either while the library is included.

Any help is appreciated.

      Does hello world work? You should’ve gotten at least some console output.

      #include <stdio.h>

int main()
{
    fprintf(stderr, "Hello world\n");
    return 0;
}

        That works perfectly

        PS C:\Users\username\3ds> gcc test.c -o test.exe 
PS C:\Users\username\3ds> ./test.exe
    Hello world

          Try adding some prints to stderr through my earlier test program then and see if you can find where it stops giving you output. Does output work before curl_easy_init? After it? Somewhere later on?

          Note that I did update the program to add the line with CURLOPT_ERRORBUFFER – that’s not strictly needed, but might provide more debug info if something goes wrong later in the program. (Forgot to add the setup line initially despite writing the rest of it… 🤦‍♂️️)

          You could also try adding curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); to get it to explain more details about what it’s doing internally if you can get it to print output at all.
