[Xymon] xymon with tls1.2

[Henrik Størner]

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
