I have a little stupid problem using gcc under MOS SDK in c++ mode.
Here a piece of the file:
-----------------------------------------------------

include <iostream.h>

// simple oo example

class animal {
int legs; // private
public:
animal(void); // costruttore
~animal(void); // distruttore
void animal::putlegs(int legs); // prototipi
void animal::putlegs(void); // polimorfismo...
int animal::readlegs(void);
};
animal::animal(void) {
cout << "Amimal initialized\n";
legs=0;
}

... and so on...
------------------------------------------------------
The OO part seems to be complied OK but I get this nasty error message
if I try to use cin/cout functions:

/t/ccjnK8bm.o: In function `animal::animal(void)':
/t/ccjnK8bm.o(.text+0x22): undefined reference to `cout'
/t/ccjnK8bm.o(.text+0x26): undefined reference to `cout'
/t/ccjnK8bm.o(.text+0x30): undefined reference to `ostream::operator<<(char const *)'
collect2: ld returned 1 exit status

What I'm doing wrong? Why I am not able to use cin/cout functions??
Thanx 4 replying this stupid question but I'd really like to learn c++!!

P.S.:Ah, I'm forgetting this little piece of code is inspired by the little
Fabio Ciucci's(aka Randy/Ram Jam in the good 90's Amiga years) c++ course.
Thanx RJ!!

Just link with libstdc++ : -lstdc++

And don't forget to put an extra space at the end of the line if you put -lstdc++ at the end.

Thanx 4 your reply Fab!
I've tried to compile with:

gcc -noixemul -lstdc++ filename.cpp

but I get always the error message.
Is the command line ok or have I missed in the source
file some #include ?
Thanx a lot & ciao!

try to add the line:
using namespace std;

Leo.

try using g++ instead of gcc.

Hi,
I've tried the clasue:
using namespace std;
+ invoiking g++ but I get always the error.
Bah, this gcc is too much "unix/style" for my experience.
Gazillions of dir with header files, softlinks, obscure
command line syntax... Not very much Amiga style!
If only I was able to start the old good HisoftC++ with the integrated IDE... But it only freeze my Peg at startup! Damnit!
Any more suggestions please?

g++ within the sdk is broken. Some links are missing. Get the proper archive from Cisc (? or whoever it was).

It would be great if the sdk would be updated...

Example:
#include <iostream> // .h is deprecated in the current C++ standard
using namespace std; // otherwise you will have to prefix calls to the std lib by 'std::'

int main(void) {
cout << "Test" << endl;
return 0;
}

The g++ that comes with the SDK should work for this simple code. AFAIK the biggest problems are with templates.
CISC's GCC can be fetched from here: http://www.morphos.org/meanmachine/files/gcc-2.95.3-bin.tar.bz2
Keep everything from the current SDK and only replace g++, cc1plus and libstdc++ wit hthe files from CISC's archive. Disabling the memory resident GCC also help resolve some problems.

@dholm
Like U've suggested I've downloaded the fixed version of CISC's GCC and replaced the 3 files as satated in your post.
Then I've launched g++ with my c++ code and i've crossed my fingers and... bang, finally it worked!
Now I can compile & run my c++ killer application, an higly OO program that displays "hello world"!!
Dholm, thanx to your precious tips AFAIK my SDK is patched and working.
-------------------------------
(Here I'd like to be able to put many dancing bananas to express my happiness! )
--------------------------------
Again, many Thanx to dholm and to other nice guys that have tried to help me.
Aloha.
