Compiling Exim 4.94 with SPF on Ubuntu

Oct 9, 2020, 5:29 AM

Post #1 of 6 (826 views)

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?

Do you have the development package
libspf2-dev
as well as
libspf2-2
?

Thanks again. Yes capital L allows spf.c to go through (as does commenting that line out) but it now fails at cc exim.c:
...
cc spf.c
cc srs.c
cc utf8.c
cc version.c
cc -o exim
//usr/bin/ld: spf.o: undefined reference to symbol 'SPF_server_set_rec_dom'
//usr/lib/libspf2.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

It’s not clear to me if this is an EXIM config issue or an error in spf2.so.2 (libspf2.so.2.1.0)

Have you tried

LDFLAGS += -lspf2

This is what the sample Makefile recommends.

Thanks again. Still the same error but I came across this <https://lists.archive.carbon60.com/exim/users/110074> . One of the commenters suggested ‘make distclean; make’, and that fixed it.

Now to configure it - and DMARC, which was the starting point of the exercise for me.
