Hello Dan,

Difficult to tell from here. ;-)

What (and how) are you trying to compile?

This may also mean that they are expected to be defined somewhere else.

As a minimal test case, could you try to compile this one:

        #include <openssl/ssl.h>

        int main()
        {
                SSL_CTX * ctx;
                ctx = SSL_CTX_new(TLSv1_2_method());
        }

so as to check the consistency of the -I, -L and -l options passed to gcc?
