Hi All,

I have three very simple files as below.
When I try and compile these with g++ -ansi -Wall -pedantic -o crap
Base.h Other.h

Why are you trying to compile a header? You compile code (.cpp) files,
not code files.

My bad. I meant to say, You compile code (.cpp) files, not header (.h)
files.

I don't use g++ but with your sample line I think you should be doing:
g++ -ansi -Wall -pedantic -o crap crap.cpp

crap.cpp itself will pull in the headers IF you use include statments.
That is, change crap.cpp to be:

#include "Base.h"
#include "Other.h"

int main()
{
}

I get an error:

Base.h:7: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Other.h:7: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make: *** [all] Error 1

Can anyone tell me why? If I remove the #include <iostream> it compiles
without error.

Thanks for your help

Michael

-----------first file--Base.h--------

#ifndef _Base_
#define _Base_

#include <iostream>
class Base {

};

#endif

-------------second file--Other.h-------

#endif

#ifndef _Other_
#define _Other_

#include "Base.h"

class Other {

#endif

-------------Third file---crap.cpp-------

int main(){
