Attached my code. I tried to make it work for linux but was unable to
test it, I don't know much about linux. I get this error when running
dmd on debian:
./dmd: error while loading shared libraries: libstdc++.so.5: cannot open
shared object file: No such file or directory
I tried to install libstdc++ libs but the error remains.

I'd appreciate it if someone could help by getting the code to work for linux or helping me fix my problem :)

From my own experience, that means you have to update a lot of things, not only that one, and with very recent versions.

I've attached a slightly modified socket.d. From what I can remember:
- version(linux) instead of Linux
- declared fd_set for BsdSockets
- blocking in Socket class was only defined for Windows, although being used
in both versions. Commented out the line
- errno declared as extern(C)

I think that's it.

I tested it on RedHat 9, and it compiled without a problem, but when testing it, I got "Socket select error". Any ideas?

Yes, fd_set is handled differently for linux, I'm working on it now. I got DMD to work on linux. Thanks for your help.

I have tested it on Slackware and run fine with some changes....

At first, the "Socket select error" is right, because you haven't a http server listening at 127.0.0.1 port 80

The second is that Socket.select is not right implemented for linux (at first reading of socked.d) comment it on and will run ok.

try this modified version for sockettest.d (watch the commented lines, real IP number and s.send string with a true http site.... ;-) :

import socket;

// dmd sockettest socket ws2_32.lib


int main()
{
	
	/+	//regular blocking
	Socket s = new Socket(AddressFamily.INET, SocketType.STREAM, ProtocolType.IP);
	s.connect(new InternetAddress("127.0.0.1", 444));
	s.send("Foo!");
	printf("Local=%.*s, Remote=%.*s\r\n", s.localAddress().toString(), s.remoteAddress().toString());
	s.close();
	+/
	
	
	/+
		//nonblocking with select()
	Socket s = new Socket(AddressFamily.INET, SocketType.STREAM, ProtocolType.IP);
	s.blocking = false;
	assert(s.blocking == false);
	SocketSet sset = new SocketSet(1);
	sset.add(s);
	s.connect(new InternetAddress("127.0.0.1", 444));
	printf("select=%d\r\n", Socket.select(null, sset, null, 1000)); //wait for connection
	s.send(cast(dchar[])"Foo!");
	sset.reset(1);import socket;

// dmd sockettest socket ws2_32.lib


int main()
{
	
	/+	//regular blocking
	Socket s = new Socket(AddressFamily.INET, SocketType.STREAM, ProtocolType.IP);
	s.connect(new InternetAddress("127.0.0.1", 444));

Here we go, Socket.select() is working on linux! Seems to be all good now.

Only change in socket.d

extern int errno; to ->  extern (C) int errno;

at line 144

It's already in an extern(C) block, and I think extern(C) is different from just extern..

Sorry, I'm wrong. I didn't realize extern was short for extern(D).

I guess this one could be considered socket.d 1.0. I've tested it pretty well, even made a test server that accepts multiple connections, listener.d included. It works good for windows and linux.

Still needed:
- Host name resolving
- Socket stream class
