That last question is the correct guess. /etc/ld.so.conf will tell
you what your default paths are (and if it includes other files, so
The are two ways to handle this. One is with the usual setting of
$ LD_LIBRARY_PATH=`pwd` ldd libssl.so.1.0.0
The other is, when you compile your application, to use
Incidently, I think that when you do this, you'll find that it finds
your libraries all right:
$ ldd /prefix/openssl/bin/openssl
The reason is that the application has been built with said -rpath
A last note: with OpenSSL 1.1.0 and on, rpath isn't automatically
applied to the openssl application, but is a matter of extra
