dev-cpp-users Mailing List for Dev-C++

Hyia Hugo.
This kind of error is common if you don't have set the Include and Library
files path (normaly, when you install the DEV-C++ without MinGW)
First of all, you must set up the correct path of the Include and Library
files in compiler options.
To have a better view of it, try to install he standard DEV-C++ with MinGW,
open it, go to "Compiler Options", "Directories", "C++ Includes".
You'll shall see in the box something like:

X:\Dev-Cpp\lib\gcc\mingw32\3.4.2\include
X:\Dev-Cpp\include\c++\3.4.2\backward
X:\Dev-Cpp\include\c++\3.4.2\mingw32
X:\Dev-Cpp\include\c++\3.4.2\
X:\Dev-Cpp\include

change the paths to the new 4.4.0 might  be like:

X:\Dev-Cpp\lib\gcc\mingw32\4.4.0\include
X:\Dev-Cpp\include\c++\4.4.0\backward
X:\Dev-Cpp\include\c++\4.4.0\mingw32
X:\Dev-Cpp\include\c++\4.4.0\
X:\Dev-Cpp\include



And, as Per answear says, the other lines is because the recursive inclusion
of files.
If you look inside the iostream header, you'll see ohter include files that
apears in the erros.


Change de C++ includes will make de Dev-Cpp look at the correct libraries
and includes.

Programador e Depurador Assembly em Arquiteturas RISC Microchip 8 bits
(eca!).
(famílias PIC12*, PIC14*, PIC16* e PIC18*).

Seems to be a problem with the MinGW installation. If your MinGW
installation doesn't allow you to build your source from the command line,
then the Dev-C++ IDE will also have problems.

That your source code file only has 10 lines is irrelevant. If you look
closer at the error messages, they not only mention line numbers, but also
the corresponding source file. The recursively included files most
definitely have more than 10 lines...

I am working with DEV-C++ version 4.9.9.2 and MinGW compiler version GNU 4.4.0. 
I downloaded the following files:
    binutils-2.19.1-mingw32-bin.tar.gz
    w32api-3.13-mingw32-dev.tar.gz
    mingwrt-3.16-mingw32-dev.tar.gz
    mingwrt-3.16-mingw32-dll.tar.gz
    gmp-4.2.4-mingw32-dll.tar.gz
    libiconv-1.13-mingw32-dll-2.tar.gz
    mpfr-2.4.1-mingw32-dll.tar.gz
    pthreads-w32-2.8.0-mingw32-dll.tar.gz
    gcc-core-4.4.0-mingw32-bin.tar.gz
    gcc-core-4.4.0-mingw32-dll.tar.gz
    gcc-c++-4.4.0-mingw32-bin.tar.gz
    gcc-c++-4.4.0-mingw32-dll.tar.gz
    mingw32-make-3.81-20080326-3.tar.gz

And I installed the decompressed files into Dev-C++ directory to have a C++ enviroment

To test the enviroment and the compiler, maker and linker, I run the following source code that was write in a file with name: 

No_Bytes.cpp:

#include <iostream>

using namespace std;

int main()
{
    return 0;
}
Only 10 lines of source code

And the compiler gave me the following messages:

The compiler gave me other messages:

Like I told you, the original source code file only has 10 lines, BUT THE COMPILER TELL ME SOMETHING ABOU LINES: 42,39, 40,2 

159, AND 166. What it means?

There is only one error, ...but I do not know why the compiler talks about functions not declared (swprintf and vswprintf. Are 

they C functions? Who call it and why?
