Can't build proton-c undefined symbols ERR_get_error etc

Hi all

We are having problems building proton-c on our dev boxes (Red Hat
Enterprise Linux Server release 5.3 (Tikanga)).  I've done a git
bisect and discovered that it was Andrew's commit last Wednesday (rev
1417553) that has introduced/exposed the issue.  Before that point, we
could build without this issue.

It appears to be a link issue with openssl.  The following version of
openssl is installed:

$rpm -q openssl
openssl-0.9.8e-7.el5.x86_64
openssl-0.9.8e-7.el5.i686

Make is failing with the following (complete cmake/make output attached below)

I am not able to determine the underlying cause (my C skills are ten
years rusty), would someone be able to take a look and advise?

Kind regards Keith Wall.

For reference, the complete make output:

Looks like -lcrypt might be missing.

It seems that the link process is not resolving all the symbols it
needs.

That change introduces checking to be sure that all symbols used by the
link are actually present somewhere. The simplest explanation is that
openssl is not being linked in the final link, but is being detected
enough to activate the code using it.

Could you run "make VERBOSE=1" and post the final link line (only).

As a workaround you can turn this checking off with "cmake
-DENABLE_UNDEFINED_ERROR=OFF". However if the warning is good then you
shouldn't actually be able to run code with ssl connections (unless you
link the final executable with openssl, which isn't really necessary).

Another useful datapoint would be to build with the above flag and then
post the results of "ldd libqpid-proton.so".
