[Dev-C++] compilation problem

[<mar...@po...>]

Hi,

I am newbie in DevC++ and gcc so excuse me my question.
And sorry for my English.
I have got the C++ sources which I can compile successfully with gcc 3.2 at
Cygwin.
What changes should I make to these sources in order to compile them in
DevC++.

Does DevC++ 5.0 use gcc 3.2 ?
May I use gcc makefiles in DevC++ ?


Below, there is a fragment of code that causes compilation error -
strstream, strstreambuf,
istrstream and ostrstream - not declared.

I could be wrong here, but: are you sure the compiler you use with Cygwin 
is *version 3.2* of Gcc?  Don't you get an error related to the header file
"strstream" when using Gcc 3.2 under Cygwin?

IMHO, You should, because the header "strstream" does not exist; generally,
one has:
 - pre-ISO C++ compilers:  "strstream.h"   or   "strstrea.h" (8-char issue)
 - ISO-C++: "sstream"

No changes is required to the source files, as these are processed by
the underlying compiler

AFAIK, you may set up any version of Dev-C++ to work with any version
of Gcc, because, basically, what Dev-C++ uses is the name of the compiler
(Gcc) and a few options, other stuff is under the control of the user.
In principle, you may hack Dev-C++ (without recompilation ;-) to use
other compilers too. 



> May I use gcc makefiles in DevC++ ?

The answer is both: no and yes :-)
 - no because there doesn't seem to be (yet) an utility that converts 
   makefiles into Dev-C++ project files 
 - yes because you probably have the program Make (which comes with
   Gcc) and so can use the makefiles directly to compile your program
