[Perl-openssl-users] Re: Crypt-OpenSSL-RSA-0.22 won't compile.

John,

I'm not sure why this isn't working for you; this is the first report
I've had of behavior like this.

The constants it's complaining about *should* be defined in the openssl
include files.  For example (in my installation, version 0.9.7e), both
the MD5_DIGEST_LENGTH macro definition and the MD5 function declaration
are in /usr/include/openssl/md5.h, which is included
by /usr/include/openssl/evp.h, which in turn is included
by /usr/include/openssl/pem.h, which gets included
by /usr/include/openssl/ssl.h.  Finally, RSA.xs contains the line:

#include <openssl/ssl.h>

which means that (again, with my installation), MD5_DIGEST_LENGTH is
defined, and MD5 declared.  The question is then why it's not getting
defined on your installation.   

You mention you are using slackware 10.2; what version of openssl does
that come with?  Does it contain the aforementioned files (either
in /usr/include, or some other place in your include path).  If so, does
md5.h contain a definition for MD5_DIGEST_LENGTH and a declaration of
the MD5 function?
