I'm trying to compile in dkim support into the 4.69 codebase on OS X
10.4.11
I've downloaded, compiled and installed openssl 0.9.8h and gotten
sha256 support there.
I downloaded the libdkim from here:
http://duncanthrax.net/exim-experimental/libdkim-1.0.16-tk.tar.gz
and compiled that and all looks good.
I've put my configs for adding dkim support into exim's Local/Makefile
My issue is at the end of make during the linking process:
cc -o exim
/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: Undefined symbols:
_SSL_CTX_set_info_callback
_EVP_sha256
_BIO_set_flags
collect2: ld returned 1 exit status
make[1]: *** [exim] Error 1
make: *** [go] Error 2
I'm stumped, anyone got any pointers?
