Strange installation problem (g++)

[boabear]

Hi all, I am trying to install ddd on my debian and I am getting the : c++ compiler cannot create executables error massage. The log file shows the following :

configure:1314: checking whether we are using GNU C++
configure:1323: g++ -E conftest.C
configure:1342: checking whether g++ accepts -g
configure:1530: checking whether the C++ compiler (g++) compiles a simple program
configure:1551: g++ -o conftest    conftest.C  1>&5
configure:1545:22: error: iostream.h: No such file or directory
configure: In function 'int main()':
configure:1547: error: 'cout' was not declared in this scope
configure: failed program was:
#line 1544 "configure"
#include "confdefs.h"
#include <iostream.h>
int main() {
cout << "hello, world!";
; return 0; }

I guess this is a backwards compatibility problem… I have compiled and ran the following program:

#include<iostream>
int main(){
	std::cout << "hello world";
	return 0;
}

And it runs perfectly.
So I guess what I need is some flag I can place in CXXFLAGS so it will run programs from back in the day when include<iostream.h> was exactable. or some other solution. Any help will be appreciated.

What version of gcc/g++ are you running? You may need to install an older compiler if you can't get the CXXFLAGS set properly. FWIW, you can have multiple gcc environments installed on your system simultaneously. I usually have 3 or 4 for just such reasons, such as 2.95, 3.4, 4.1, and 4.4 or 4.5.
