 |

could someone throw me a bone (even a frikkin' one) here, it's late and i'm pretty sure i'm missing something obvious.
| Code: | $ g++ Vector.cpp -o Vector.o
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/../../../crt1.o(.text+0x18): In function `_start':
: undefined reference to `main'
collect2: ld returned 1 exit status |
thanks.

What's the code you're trying to compile?
Do you have a main() function defined? g++ is trying to create an executable, so its looking for main() when its linking. Try going this:
| Code: | | g++ -c -o Vector.o Vector.cpp |
That should let it compile...
HTH
edit: The -c tells g++ (or gcc for that matter) that it should only compile, not link.
