Error from gcc compiler

What does the following error mean:

In function `get_ints`:
`l` undeclared (first use in this fu开发者_如何学编程nction)

Thanks, Josh

The compiler complains about variable l being undeclared. Just from experience - check your integer constants, there's a chance you have l instead of 1 somewhere there.

You used l somewhere and didn't define it.
