The symbol get_rfc3526_prime_8192 is part of OpenSSL even in 0.9.8.
Let's try to find out, why it can't be found.
Assuming Linux for the following.
First look at your library file
/home/admin/tomcat/tcnative/tomcat-native-1.2.10-src/native/.libs/libtcnative-1.so.0.2.10.
Check whether is has an external dependency on libcrypto, what is the
RUNPATH and/or whether the symbols are statically compiled in:
- What is the output of "objdump -p
/home/admin/tomcat/tcnative/tomcat-native-1.2.10-src/native/.libs/libtcnative-1.so.0.2.10"?
- What is the output of "nm
/home/admin/tomcat/tcnative/tomcat-native-1.2.10-src/native/.libs/libtcnative-1.so.0.2.10
| grep get_rfc3526_prime_8192"?
Next: assuming you linked against the dynamic libcrypto library, where
is your libcrypto.so.1.0.0 for OpenSSL 1.0.2 located? Is it inside
/home/admin/tomcat/tcnative/tomcat-native-1.2.10-src/native/.libs
(unlikely) or somewhere else? How is Java expected to find it there? Did
you add the directory to LD_LIBRARY_PATH?
Finally check the libcrypto.so.1.0.0 from OpenSSL 1.0.2 whether it
contains the symbol: what's the output of "nm
/path/to/my/libcrypto.so.1.0.0 | grep get_rfc3526_prime_8192"?

Rainer
