Hi Marek,
Thanks for your reply.
I think the libssl.a and libcrypto.a should be ok. Maybe myAPI.a had failed to link libssl.a and libcrypto.a into itself?
Later I try another way: when I make myUI, I link to not only myAPI.a, but also libssl.a and libcrypto.a all. It seems that the openssl api can be found.
Now, my question is: Can I link a lib(.a) into another lib(.a)?
Thanks a lot!
Best Regards!
Best Regards!

Your static library is only a set of object files created with ar
command - nothing more. You may look inside with command:
$ ar tv myAPI.a
to check its contents, you may look in OpenSSL library:
$ ar tv libcrypto.a
to check that this object files are not in your library.
Best regards,
