FreeBSD freebsd 10.0-RELEASE-p1 FreeBSD 10.0-RELEASE-p1 #3 1c0248c(releng/10.0): Fri Dec 20 16:30:45 EST 2013 root@avenger:/usr/obj/root/pcbsd-build10.0/git/freebsd/sys/GENERIC amd64
>Description:
Hello,
When built with OpenSSL support enabled (which happens to be the default configuration) the libzrtpcpp port included in FreeBSD does not produce a functional shared library, because a bug in src/CMakeLists.txt in the source code of libzrtpcpp prevents the shared library from including essential object files.
The problem can be reproduced using the shell snippets in the "How to repeat the problem" section.
Please note: the linker warnings related to the version of libcrypto and libssl are not related to this bug.
Thank you,
M. Vefa Bicakci
