Hi,
The default settings for CC and USE_DB for FreeBSD seem to be out-of-date.
1. Since FreeBSD 10.0-RELEASE on most platforms, FreeBSD has not included
gcc in the base OS --
https://www.freebsd.org/releases/10.0R/relnotes/#userland
I'd suggest setting CC=cc in OS/Makefile-FreeBSD to use the clang compiler
instead.
2. Makefile-FreeBSD enables the use of FreeBSD's built-in Berkeley DB,
which is no longer useful because it's Berkeley DB v1. That causes the
error below. I'd suggest removing USE_DB from OS/Makefile-FreeBSD. Since
FreeBSD also includes ndbm.h, Exim will use that instead.
Thanks,
David Siebörger
