[Xymon] xymon with tls1.2

Hi Frank,

what happens if you leave out the --ssllib and --sslinclude parameters? It is an unusual location for OpenSSL to be installed, so I guess you compiled it yourself?

It also ought to pull in libdl.so automatically, but that probably requires some magic when compiling OpenSSL.

Anyway, I believe you can work around it by setting NETLIBS in xymon-4.3.27/build/Makefile.Linux like

NETLIBS="-ldl"

Regards,

Henrik

Hi everyone,

We are changing all our SSL web sites on windows over to tls1.2. So I have upgraded the openssl on the xymon server.

 I have run into an ssl issue compiling xymon-4.3.27 and xymon-4.3.28

openssl is in /usr/share/openssl-1.0.21

./configure.server --ssllib /usr/share/openssl-1.0.21/lib --sslinclude /usr/share/openssl-1.0.21/include

This is my error:
