## #5336 — Brian J. France — 2003-11-11T04:19:36+00:00

I am having a problem building snmp as a shared extension since the move to 
PHP_SETUP_OPENSSL.

The big problem is libssl.so on FreeBSD doesn't have a dependence on 
libcrypt.so, but I don't think I can get fixed anytime soon.

When running ./configure for the shared extension it fails for the test of 
SSL_CTX_set_ssl_version because of undefined symbols.  This is because it is 
only linking with -lssl and not -lssl -lcrypto.

Short of hacking the generated configure script and adding:

   LIBS="$LIBS -lcrypt";

right before the SSL_CTX_set_ssl_version, I don't know how to fix it.

Any ideas?

Thanks,

Brian
