Check this code:
String error;
String result = HttpClientGet("someserver.com/somefile.txt", NULL, &error);
if(result.IsEmpty())
Cout << "Error: " << error << "\n";
Runs OK on windows, but prints this error in linux:
Error: socket(3) / connect(someserver.com:80): Operation now in progress
HttpClientGet is supposed to download the file during the call, and not return until ready or timeout, correct?

On linux WSAEINPROGRESS is sent when "An operation that takes a long time to complete (such as a connect) was attempted on a non-blocking socket." I tried with blocking sockets and it works. I modified one line in HttpClient::Execute, instead of:
if(!socket.IsOpen() && !ClientSocket(socket, sock_host, sock_port, true, NULL, 0, false)) {
rather:
if(!socket.IsOpen() && !ClientSocket(socket, sock_host, sock_port, true, NULL, 0, true)) {

Now, this is clearly an error and one that I hope to fix easily. It is not very handy to create the socket itself as blocking because it can hang the application for a long time during the connect / receive calls. The trouble is probably caused by the fact that Windows and Linux use different error codes to report an unfinished blocking operation (Windows = EWOULDBLOCK, Linux = EINPROGRESS).
