18.1 Qmail Won't Compile

You have unpacked the qmail sources and typed make, but it won't compile. If you're receiving error messages about errno, you've run into a compatibility problem between qmail and recent versions of the GNU C library. The fix is very simple. See Building with Recent GLIBC and Fixing the errno Problem in Chapter 3.

(This is the number one question on the qmail mailing list, so frequent that there's an autoresponder that mails back the answer to any message that contains the word "errno".)
