| Naturally. Try "man gcc" and search the rather lengthy list of options. In particular:
-Werror
Make all warnings into errors.
You need to take that out of your makefile. |

| | By consulting "man write" ( you may need to try "man 3 write" ) and seeing which includes it lists as required in the page that discusses the function. This method will work for most glibc library code. | | Top |

| | As Nick showed, the required include files will be noted in the manual of what you're using. |

| | It was sort of a lucky guess on my part the first time I tried something like "man 2 write". I had noted that at the bottom of a man page I was looking at that some of the listings had (1) or (3) after them. So I figured I'd find out what using those would do for me and found what I was after :) | | Top |
