According to Florent <greenpenguinNOSPAM at free.fr>:

I think you're picking up the wrong OpenSSL on your system.

Here's what 0.9.4's HMAC_Update looks like:

    $ egrep HMAC_Update /usr/include/openssl/hmac.h
    void HMAC_Update(HMAC_CTX *ctx,unsigned char *key, int len);

Here's what 0.9.6's looks like:

    $ egrep HMAC_Update /usr/local/include/openssl/hmac.h
    void HMAC_Update(HMAC_CTX *ctx, const unsigned char *data, int len);

The OpenSSL you're linking with is probably built without -DBIO.

SSL_MODE_AUTO_RETRY is new in 0.9.6. 0.9.4 doesn't have it.


Check that you are indeed using the correct OpenSSL includes and libraries.

Cheers.
