Disabling exception handling (if/where possible) may save you another 8-10%.

if( (master_socket = socket(AF_INET , SOCK_STREAM , 0)) == 0)
creates a TCP socket, not an UDP one. Later on, you bind that socket to an address and listen on it.
UDP sockets work a...

If position is > vector.size(), the vector will throw an out_of_range exception.

It looks like your server is only listening on "127.0.0.1". You need to listen on any available address, or at least on a network address reachable from the outside.
This leaves you with a memory leak. The new Worker object is a temporary object you can never delete. Since you are not using it anyway, your method could be defined like this
template<class T> ...
Apart from what OReubens suggested, I recommend not to return a raw pointer to the object, but a smart pointer. This relieves the caller of createObject from the question of the ownership of the...
Is UTILITIES_EXPORT in your program defined correctly?

IIRC, something like
printf("%*s", countBackspaces, tmpString );
but shouldn't this be "spaces" or "blanks" instead of backspaces?

While your PATH point to D:\mingw32\bin, your shell complains about "/D/mingw64/bin/make.exe", so maybe there is a colon missing after the "D"?

In VS2010, it's "Debug - Start without Debugging" or Ctrl + F5.
In other versions, it might be similar.

A scalable server, this looks like a task for IO Completion Port. My first thought was about ::select(), but that cannot handle a large number of sockets, IIUC.

Did you run the program in the debugger? That should be pretty straight forward and show you what's going on.

Well, it tells you what's wrong:
"error: directory name must immediately follow -I"
This means that in your line
g77-3.3 -I ./src/src_common_depend/
there is one blank too much: between the I and...
Yes, that's what I was thinking of, but didn't want to post because it is so simple.
First of all, please use code tags when posting source code.
Then, never place a "using" directive in a header file. For a discussion, see this link:...
It is most likely that the compiler does not know of the Idle class as it is defined after its first use in line 1. Moving the first line after the class definition should solve this issue.
I think you are confusing two things:
1. when setting up a connection, you always use the host byte order, because that is what is used internally on the system you are working on. It is the OS's...

ios::out erases an existing file. So if you open an existing file with that option, then seekp to a position, all bytes before that position are filled with 0x0.
It's not Philip Nicoletti's...

I only have g++ 4.6.1, but looking at /usr/local/include/c++/4.6.1/mutex it seems that the mutex class is protected by some #defines.
I found a (german) article on the web which mentions that you...

Did you use the debugger to debug your code?
What if either con, stmt or res are nullptrs? The example relies on them not being nullptrs, but if they are, your program will crash as it does.

What compiler do you use?
What error messages do you get?
