Curl on Windows

Building libcurl on Windows

As of curl-7.35.0 please apply the following patches.

1. http://curl.haxx.se/mail/lib-2014-02/0003.html
2. http://curl.haxx.se/mail/lib-2014-02/0097.html
3. http://curl.haxx.se/mail/lib-2014-02/0118.html

This works with dmd 2.065 beta 3. It does not work with dmd 2.064.

Required tools

• MinGW (http://www.mingw.org)
• Digital Mars' implib (http://ftp.digitalmars.com/bup.zip)
• MinGW-w64 (http://mingw-w64.sourceforge.net/)
• Microsoft Librarian (lib.exe)
• pexports (http://sourceforge.net/projects/mingw/files/MinGW/Extension/pexports/)
• Sample program app.d

import std.net.curl;
import std.stdio;

void main()
{
	writeln(get("https://google.com/"));
}

Building libcurl 32 bit
