When I start BitTorrent Sync (btsync x64 build) 1.4.110 on a fresh install of Fedora 21, using a configuration file known to work on a different system, I get this perplexing error message:

$ btsync --config /home/user/.btsync.conf
btsync: /mnt/jenkins/workspace/Build-Sync-x64/linux/breakpad/client/linux/handler/minidump_descriptor.h:55: google_breakpad::MinidumpDescriptor::MinidumpDescriptor(const string&): Assertion `!directory.empty()' failed.
Aborted (core dumped)

I don't have Jenkins installed on this system. It looks like the BitTorrent Sync build compiled with symbols from the BitTorrent organisation's release engineering build server environment. Heh.

What is the problem? Here is my configuration file from /home/user/.btsync.conf:

{
  "device_name": "MyLaptop",
  "listening_port" : 0, // 0 - randomize port

  }

      [

      ]
    },
    {

The problem turned out to be the configuration of the following folders:

  • /home/user/.btsync -- the folder to hold BitTorrent Sync meta-data
  • /home/user/SyncFolder1 -- a folder to sync
  • /home/user/SyncFolder2 -- a folder to sync

When btsync started, the meta-data folder /home/user/.btsync did not exist. I created it, and made sure that it was writable by my user account. I also created both sync folders. After these folders were created, btsync started normally:

$ btsync --config /home/user/.btsync.conf

BitTorrent Sync forked to background. pid = 15949. default port = 8888
