Hi,

I wrote a (very) small program in C++, and I wanted to compile it with
DJGPP.

/* hello.cc */

#include <iostream.h>

int main()
{

cout << "Hello!" << endl ;

}

Then I wrote its makefile:

hello:	hello.o
	gcc hello.o -o hello.exe -lm -ansi

hello.o:	hello.cc
	gcc hello.cc -c -ansi

Then I tried to make it but it failed at linking saying:

hello.o(.text+0x12):hello.cc: undefined reference to 'endl (ostream&)'
hello.o(.text+0x1C):hello.cc: undefined reference to 'cout'
hello.o(.text+0x21):hello.cc: undefined reference to
'ostream::operator<<(char const*)'
hello.o(.text+0x2C):hello.cc: undefined reference to
'ostream::operator<<(ostream &(*)(ostream &))'

I looked in the libraries with nm and it seems that they are there.

I have been trying to solve the problem myself for hours and hours but I
didn't succeed, so I wrote this message to ask for help.

Thanks.
