Cannot link with SSL Library
New installation of Xymon 4.3.21 on OpenSUSE 13.2. Xymon won't compile with SSL support even though I have OpenSSL and libopenssl-devel installed. When I run "openssl version" it says OpenSSL 1.0.1k-fips. Here is what I see when I run ./configure: (note: I also tried running configure.server with -sslinclude and -ssllib). When I run "openssl verions -a" I don't see gcc listed under compiler. I see "-I. -I.. -I../incluse -fPIC" etc. I may have installed gcc after openssl, but gcc is installed.
Checking for OpenSSL ...
Compiling with SSL library works OK

Warning: Cannot link with SSL library

Although you can use Xymon without OpenSSL, you will not
be able to run network tests of SSL-enabled services, e.g. https.
So installing OpenSSL is recommended.
OpenSSL can be found at http://www.openssl.org/
If you have OpenSSL installed, use the "--sslinclude DIR" and "--ssllib DIR" options to configure to specify where they are.

It seems that your openssl libraries do not automatically pull in the libdl library when you link with it.
As a workaround, you can change build/Makefile.test-ssl: The "test-link" command reads @$(CC) $(CFLAGS) $(OSSLLIB) -o test-ssl test-ssl.o -lssl -lcrypto $(NETLIBS) Add a "-ldl" after the "$(NETLIBS)".
That should allow the configure script to complete. After that, you must change the top-level Makefile: It has a line with SSLLIBS = -L/usr/lib -lssl -lcrypto Change that to SSLLIBS = -L/usr/lib -lssl -lcrypto -ldl

Thank you. This work-around, worked. I had to delete my Xymon install folder and un-package a fresh copy, but once I did that and followed these instructions, Xymon compiled with OpenSSL support.
