Can this Errors be ignore?

[yoom@xxxxxxxxxxx (Yoom Nguyen)]

Can the following error to be ignore?

I received the following errors after ran     make test:

/usr/bin/ld:  cannot find -lssl
make[2]:  *** [link_app.gnu] Error 1
make[2]:  Leaving directory '/opt/software/openssl-1.0.2a/test'
make[2]:  *** [bntest] Error 2
make[2]:  Leaving directory '/opt/software/openssl-1.0.2a/test'
make[2]:  *** [tests] Error 2



I am trying to compile 1.0.2a on an Redhat 7 EN OS.
I compile with the following options.

export CFLAGS="-fPIC"
./config shared no-ssl2 no-ssl3 --openssldir=/usr/local/openssl


Any suggestion or advice will be much appreciate.

Thank you 
Y
