Or maybe I don't understand LD_DEBUG. I tried uncommenting the "share_folders" in the config file. First run, the the threads stay alive and the sync.log reports "MY_SECRET_1" is not a valid secret. I use the command-line to generate a secret and use this in the config file. Now, the threads die and stderr reports "./btsync: relocation error: ./btsync: symbol inotify_init, version GLIBC_2.4 not defined in file libc.so.6 with link time reference" So, I run "LD_DEBUG=bindings ./btsync | grep inotify". Nothing. This is why I'm thinking LD_DEBUG=bindings only shows SUCCESSFULLY bound symbols....
