    Strange installation problem (g++)

    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:
    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.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    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.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
