Problems with ssl acceleration on 2.5.PRE

Hi All,

Been having problems compiling squid with ssl acceleration on Redhat 6.2. I
was having problems on 7.2 as well but seem to have fixed these. I've now
worked out the problem with 6.2 and hence are submitting this bug report
(but I'm not sure of the best way to fix it) with compiler output at them
bottom of the message.

When it compiles the squid binary and tries to link in the ssl/crypto stuff
in fails with the undefined reference to dlclose/dlopen/dlsym functions. The
reason this is happening is because it needs to use the -ldl (dynamic loader
library) compiler option. If I manually compile the line after it fails and
add the -ldl compiler option into the line it compiles just fine. The line
compiles fine in 7.2 without this option (not sure why) but is needed in
6.2. The Makefile makes mention of this option with the DLLIB=-ldl line but
doesn't appear to use it. From what I've read on the openssl lists this
problem appears with openssl versions 0.9.6b and later (I'm using both
0.9.6b/c). There is mention of this problem on the openssl-users mailing
list here
http://www.mail-archive.com/openssl-users@openssl.org/msg23323.html

Unfortunately I'm just learning about the wonders of autoconf and make and
aren't sure the best way fix this so any pointers to good doco (and a patch
for my current problem) would be much appreciated so I can get on to my next
problem.

Regards
Peter
