hmm, it is curious that it would do this.

Certainly with C and gcc you would compile your c program with

gcc prog.c

this would give you an a.out binary

or more usually you would do

gcc -o prog prog.c

which will give you a binary called prog

this .o stuff is for when you have multiple source files that you want
to compile and produce individual object files which can then be linked
with your main program file which contains the 'main' function.

e.g

gcc -c strfuncs.c
gcc -c mathfuncs.c

will produce strfuncs.o and mathfuncs.o

which can then be linked in with your main program

gcc -o prog prog.c strfuncs.o mathfuncs.o


prog.c contains the main function and will also call functions contained
in the two .o files.

OK, heres a VERY basic example.

add.c

int add (int a, int b)
{
        int c;

        c = a+b;

        return c;
}


mul.c

int mul (int d, int e)
{
        int f;

        f = d * e;

        return f;
}


sums.c

#include <stdio.h>

void main ()
{
        printf ("addsum = %d, mulsum = %d\n", add (2, 3), mul (5, 8));
}


gcc -c add.c
gcc -c mul.c

gcc -o sums sums.c add.o mul.o



I would have thought that this would be pretty much the same for C++/g++
