It was already correctly confirmed in this thread.

It's not paranoid, it's a logic and normal question.

For me, but as to be confirmed by freeswitch dev and c expert, FS compile with linked library by default. And doing :
$ ldd <path_to_fs>/bin/freeswitch 
show you the linked librairy with your binary on your system.

If someone else can confirm my post too, I'm not 100% sure.

Thanks

Yep, just being paranoid and want to absolutely confirm that the standard FreeSWITCH build links libraries (including glibc) dynamically.

There is no need to rebuild an application linked against a dynamic library.
