I have been runninng exim-4.96 since RC0 on FreeBSD (I think from
12-RELEASE, thanks to @Jeremy Harris <jgh@???> and others) and what
I have is:
/etc/make.conf:
CC=clang
CXX=clang++
CPP=clang-cpp
The Makefile in use in exim-4.96/Local/Makefile is:
https://pastebin.ubuntu.com/p/5zDnWMYwPx/
I hope one day exim-4.96 will make it into the ports, but I did not have to
wait.
At some point, @Jeremy Harris <jgh@???> advised me that I could use
the below if I want to move from BDB:
For TDB:
USE_TDB = y
DBMLIB = -ltdb
For gdbm:
USE_GDBM = yes
DBMLIB = -lgdbm
I have successfully used tdb on my Linux servers, but I have not done so on
FreeBSD - because I never bothered to.
I am running exim-4.96 on a few FreeBSD 13-RELEASE servers and also a few
Linux (Ubuntu & Debian) for quite some time now.
HTH.
