Summary: Curl OpenSSL not compatible with 7.17 or 7.18

Initial Comment:
Not compatible with open ssl on these versions, as you can't compile as it doesn't recognise where the ssl lib is

This problem seems to be that his version of OpenSSL needs -ldl added to
LDFLAGS and our configure script doesn't try that (and I don't think we
should either since that'll only turn into a futile race we cannot win).
The only sane work-around for users is to use the pkg-config approach as
mentioned by Dan F. Thus, I no longer consider this a bug.

Of course a less generic work-around is to explicitly add -ldl to LDFLAGS
when invoking configure.

This sounds like a duplicate of

Can you try the advice suggested there and report back?

first of all thankyou for assissting me. is there a single file curl is
looking for or a group of folders?
i installed openssl from source with the command ./config
--prefix=/usr/local/ssl . i don't know if it has shared libs, but i use
openssl with apache (if that is a shared lib)
config.log in 7.16 (ssl parts): ./configure --with-ssl:

Can you show us your config.log file, or at least the openssl related
parts of that file?

Do you have any shared OpenSSL libs in /usr/local/ssl/lib or are they
static only?

What if you run configure with just "--with-ssl" without specifying the
path? (You're using the default path anyway)

Please be more specific about exactly what doesn't work and what you did
when it failed.

curl has been built against OpenSSL for ages and countless people have
done so using the curl 7.17 and 7.18 series as well. Me included.
