I am attempting to add SPF to an Ubuntu 18.04 Exim installation (compiled from source, not the Ubuntu package), but Exim compilation fails:
cc -DMACRO_PREDEF macro_predef.c
In file included from exim.h:494:0,
from macro_predef.c:12:
spf.h:17:10: fatal error: spf2/spf.h: No such file or directory
#include <spf2/spf.h>
^~~~~~~~~~~~
compilation terminated.
I have this in Local/Makefile:
SUPPORT_SPF=yes
CFLAGS += -I/usr/include
LDFLAGS += -l/usr/lib/spf2
Ubuntu has libspf2 installed (in /usr/lib) but this does not include spf.h
I have tried compiling libspf2-1.2.10 from source but this fails with several errors, finally:
Makefile:228: recipe for target 'all' failed
make: *** [all] Error 2
(It looks like libspf2 is now quite old (2010?) and links to their support forums are dead.)
There is spf.h at exim-4.94/build-Linux-x86_64/spf.h. Can I use this and if so where should it go?
