Problema Gcc En Dev

[jask2007]

Que tal compañeros:

Les expongo mi problema:

Desde hace ya tiempo programo en C++, y desde que descubrí el DEV cambie de borland a DEV. Ahora actualicé el compilador y ya no compila nada. Las librerías no aparecen, ya las volví a copiar de otra PC pero sigue sin funcionar.

Espero que alguien me pueda ayudar.
Saludos.

A ver...compilaba en borland...luego pasaste a DEV c++ y segui compilando??

Por ultimo actualizaste el compilador....como hiciste eso??

Postea algun error para orientarnos...o borra todo y reinstalalo.

De Borland a DEV y sigue compilando salvo algunas librerías que supuestamente son "Actualizaciones" del propio DEV, compilaba "bien". El problema es que al bajar la "actualizacion" del compilador a la 4.5 ya no compila nada de C++, es decir todas las funciones cout, cin, etc. son errores. Probé con un printf con la librería stdio y va bien. Al reinstalar compila nuevamente los cout, pero el problema es al actualizar el compilador.

Dev c++ esta descontinuado, pasate a codeblocks por ejemplo. si pones el codigo mejor, pero seguro que estas haciendo los includes con *.h.

[jask2007]

de hecho el codigo es bien simple:

#include <iostream>
#include <cstdio>
using namespace std;

main(){
cout<<"Hola"<<endl;
system("PAUSE");

}

con algo tan simple y marca error.

[enrique4480]

tendriamos las cosas mas claras si pones de primeras el codigo y los errores, caso contrario tenemos que adivinar. el caso uno no es, pues vamos por el segundo. cuando creaste el proyecto ¿seleccionaste c++ o c? .

Otra cosa, main no tiene que estar sin tipo y tiene que devolver un valor. y si ahora tampoco se te soluciona el problema pon los errores y terminaremos antes.

[jask2007]

Si el problema ya lo "resolví" agregando al compilador -enable-auto-import.

Ya compila el codigo que puse abajo. Los errores que obtenia auto-importing has been activated without, falta de librerias dll (libstdc++-6.dll y libgcc_s_dw2-1.dll)

Vaya problema, ahora con cualquier otro programa genera numerosos errores. Con la librería RAD para hacer interfaces y el siguiente codigo:

#include <radc++.h>

//create new form
Form Form1("Text event - RAD C++ Example");

//create new text box
TextBox text1("Type here", AUTO_ID, 10, 15, 200, 25, Form1);


//create new control procedure for form, procedure1 is procedure name
FormProcedure procedure1 (FormProcArgs) {

//capture event ON_CLOSE which is fired when form is closed, [X] is clicked
ON_CLOSE() {
//exit application
Application.close();
}
//capture text change event, means text hs been changed
ON_TEXT_CHANGED ( text1 ) {
Form1.caption = "Changed : " + text1.text;
}

//always return 0
return 0;
}

//rad c++ main program
rad_main()

//attach the created procedure with form
Form1.procedure = procedure1;

//set focus to textbox when program starts
text1.focus();

rad_end()

Genéra todos estos errores:
