Hi!

I'm trying to compile exim on Debian because I need SMTP authentication.

But I got a compile error on 'pcre.h' since that file is in the pcre directory.

here is the whole process :

root@mail 12:55:55 /home/elmer/exim/exim_3.12-10.1.deb/exim-3.12$ make
`Makefile' is up to date.

Am I doing something wrong?

Thanks for any responses!
