cannot compile with DomainKeys

[Code Chump]

I wonder if anyone can help?

I've been on this for days now!... and have tried everything I can think of
and find through Googling.

I cannot get Exim to compile with DomainKeys support..

I've followed all the instructions at:
http://wiki.exim.org/DomainKeys

My OS is CentOS-5.3

I can compile fine when I comment out:

EXPERIMENTAL_DOMAINKEYS=yes
CFLAGS  += -I/<path to my>/libdomainkeys-0.69
LDFLAGS += -ldomainkeys -L/<path to my>/libdomainkeys-0.69

I'm using the latest libdomainkeys 0.69 if that might be an issue.

Anyway during compile I get the error:
gcc -o exim
/usr/local/src/libdomainkeys-0.69/libdomainkeys.a(domainkeys.o): In function
`dk_free':
domainkeys.c:(.text+0x30c): undefined reference to `CRYPTO_free'

...and it's all downhill from there :-(

I have openssl & openssl-dev installed and even ended up using yum to
install the whole 'Development Tools' group from CentOS, to make sure I'd
got all the libraries.

I'd appriciate if anyone can help?

Thanks for your response. Yes I do have openssl & openssl-dev installed, as
mentioned. I wonder if they're being picked up by the compiler. They were
installed by yum, so they're were you would expect them for CentOS.

Does anyone know how to explicitly express their locations in config? Thanks

This is what I did to make it work:

To build it, I put the libdomainkey.so to be in someplace that the
linker could find it, and told exim about it:
echo "LDFLAGS += -ldomainkeys" >> Local/Makefile

Then I built it.

After installing exim, I copied the libdomainkeys.so to $LIB/exim and
can verify that it's seen by the exim binary:
CentOS52[root@ivwm51 ~]# ldd /usr/sbin/exim | egrep 'domainkeys|dkim'
        libdomainkeys.so => /usr/lib64/exim/libdomainkeys.so (0x00002ae197a6f000)
        libdkim.so => /usr/lib64/exim/libdkim.so (0x00002ae197c75000)

Truth be told, I modified an exim spec file for 4.69-7 from fc10 to
build a CentOS 5.2 rpm with dk/dkim support using the shared library
method I described above.

Thank you Todd.

To follow up for 'the record' this did work and compile under CentOS 5.3. w/
libdomainkeys-0.69 and exim-4.69. The makefile below got wrapped by email,
but following the changes, I was able to get a successful make. From there I
had to type 'make libdomainkeys.so to make the actual library and then
install it manually into the library path for CentOS, using a conf file and
ldconfig.

After that exim would build OK against this library and I'm rolling along,
thanks to your help.

Hey

I'm still not able to get it. Can you please detail out the steps a little bit more.
I've my ssl etc installed. i can't make the libdomainkeys.so file you are talking abt. What is the target in the libdomainkeys to make the .so file please?
