ie newbie
I have downloaded and installed cygwin, but I'm not sure what I do with it other than install it. Also, what is the best compiler to use for this? I'm using MSVC.NET, but maybe that's not the best for this.

Make sure you have installed the development tools. That is, typing:

gcc --version

... should show something like:


$ gcc --version
gcc (GCC) 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125)
Copyright (C) 2004 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.


rather than an error message.

You need to start up the "bash shell" that gets installed when you install cygin.

Now copy the tinymudserver_v2.tgz file into your "home" directory one way or another, and then from the bash shell unpack it:


tar xvzf tinymudserver_v2.tgz


That should create a directory "tinymudserver" with various files in it. Change to that directory:


cd tinymudserver


Then compile by typing "make:


make


That should create an executable.

I just tested it. That works, except because of tighter compiler rules I found I had to remove a semicolon from the end of lines 146, 208, 259, and 265. If you get an error you better edit the file tinymudserver.cpp and fix those lines up:



$ diff tinymudserver.cpp ../../tinymudserver/tinymudserver.cpp
146c146
<   };   // end of FindAndReplace
---
>   }   // end of FindAndReplace
208c208
<     };
---
>     }
259c259
<   void operator() (const T* ptr) const { delete ptr; };
---
>   void operator() (const T* ptr) const { delete ptr; }
260a261
>
265c266
<   void operator() (const T item) const { delete item.second; };
---
>   void operator() (const T item) const { delete item.second; }


Fixed lines in bold.

For some reason gcc didn't install the first time. I did reinstall cygwin and gcc is now in there. My gcc --version looks identical to yours now.

make still does not work... just "command not found".

Better install "make" then - that is one of the options under developer tools.

I seem to have completely different line numbers (using a win text editor)-- I think I removed the right semi-colons, but I still get errors. Just to be sure, where exactly is 208c208?

I think that 208c208 means that it's line 208 of the 'left' file compared with line 208 of the 'right' file. Basically it's complaining about there being semi-colons after function definitions. The gcc suite is getting rather good at enforcing language standards, which might seem annoying but is actually a good thing because it forces people to write cleaner code.

The line numbers should not be completely different, unless you are using a different version or something.

However you should only see one place in the source with:

// end of FindAndReplace

in it. If there is a semicolon after the } at the start of that line, that is the one to get rid of.

The place in your file should be roughly where the error message line points to.

For some reason, when I open it in Notepad++, it doublespaces the lines which causes the odd line numbers, but I guess that makes then approximately double yours. Could the double spaces be causing errors?

When I try to make after fixing those semi-colons, I get a few errors ...

I wanted to verify where exactly 208c208 was to make sure I didn't remove the wrong semi-colon...and a line of }; isn't exactly the rarest thing to find. Also, what did 260a261 indicate?

Try Crimson Editor:

http://www.crimsoneditor.com/

That is freeware, and doesn't seem to have that problem.

Or, use vi in the bash shell.

Yes, adding extra lines might throw out compilation under certain circumstances.


// string find-and-replace
string FindAndReplace
  (const string& source, const string target, const string replacement)
  {
  string str = source;
  string::size_type pos = 0,   // where we are now
                    found;     // where the found data is
  if (target.size () > 0)   // searching for nothing will cause a loop
    while ((found = str.find (target, pos)) != string::npos)
      {
      str.replace (found, target.size (), replacement);
      pos = found + replacement.size ();
      }
  return str;
  };   // end of FindAndReplace  <-- line 146




  // output to player (any type)
  template<typename T>
  tPlayer & operator<< (const T & i)  
    {     
    outbuf += MAKE_STRING (i); 
    return *this; 
    };     <-- line 208




// see Josuttis p12 and Meyers p38
struct DeleteObject
  {
  template <typename T>
  void operator() (const T* ptr) const { delete ptr; };  <-- line 259
  };




// similar concept for maps
struct DeleteMapObject
  {
  template <typename T>
  void operator() (const T item) const { delete item.second; };  <-- line 265
  };


I must have added a blank line which is why 265 became 266.

All right, this time I deleted the directory, reunpacked the file, and removed those semi-colons using Crimson Editor. There's no extra new lines now. I'm still getting several errors though:

I just downloaded that file again, and unzipped it and put it into my Cygwin directory. I typed "make" and got this:


$ make
g++ -g3 -Wall -w -pedantic -c tinymudserver.cpp
tinymudserver.cpp:146: error: extra `;'
tinymudserver.cpp:208: error: extra semicolon
tinymudserver.cpp:259: error: extra semicolon
tinymudserver.cpp:265: error: extra semicolon
make: *** [tinymudserver.o] Error 1


I love these error messages. What is the difference between "extra ';'" and "extra semicolon"?

I removed those 4 semicolons, and typed "make" again and got this:


$ make
g++ -g3 -Wall -w -pedantic -c tinymudserver.cpp
g++ -g3 -Wall -w -pedantic -o tinymudserver tinymudserver.o

$ ./tinymudserver
Tiny MUD server version 2.0.0
Accepting connections from port 4000


The file I used was:

http://www.gammon.com.au/files/muds/tinymudserver_v2.tgz

I can't explain your errors - did you use that file?

Thought I should add this in case anyone tries this later on that when you try to compile tinymudserver_v2_2.tgz (the one with seperate source files) that in addition to removing those four semi-colons, you might need to add #include <sys/errno.h> to player.cpp and #include <fstream> to utils.h before it will compile under cygwin.
