[kamailio] modules/websocket: ensure linkage to libcrypto (#439)
by Andrey Utkin 15 Dec '15

15 Dec '15

Fixes linkage for Ubuntu Wily (15.10). The issue manifests itself as "undefined symbol: SHA1" error at module loading. In Ubuntu 14 LTS (Trusty), ```pkg-config --libs libssl``` returns ```-lssl -lcrypto```, but in Ubuntu 15.10 (Wily) it returns only ```-lssl```. In the end, websocket.so gets SHA1 symbol (and some more) unresolved. For unclear reason, this change is not needed for tls.so - it gets linked to libcrypto automatically, despite it is linked only with ```-lssl``` flag. Maybe it is something symbol-specific, or something I am completely unaware of. SSL_BUILDER stuff in Makefile seems to become even more mostruous with the proposed change. Keep in mind that there is ~5 more modules with identical construction in their Makefiles. Rejection of this patch in favor of cleaner solution is appreciated.
