How-To: Headless transmission-daemon on OS X

As MacPorts is rather unhappy with Xcode 4.3 (understandably, with all those changed paths), I invested a fair amount of effort to get it recompile rTorrent (which I’d been running in a screen-session on my Mac mini). I got it work (xcode-select + setting the Developer-folder in /opt/local/etc/macports.conf to either “/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain” or “/”), but while searching around, I also came across Transmission‘s headless daemon and web-interface.

So, here’s how I built and configured the headless daemon on OS X (with Xcode 4.3):

  1. Get the source-package, e.g. transmission-2.50.tar.bz2
  2. Copy the source of libevent2 into “third-party/libevent” (“mv ../libevent-2.0.17-stable third-party/libevent” inside the Transmission-directory).
  3. Build via “xcodebuild -project Transmission.xcodeproj -target transmission-daemon -configuration Release”.
  4. Run the daemon so it creates its initial config in “~/Library/Application Support/transmission-daemon”.
  5. Edit the configuration in settings.json (whitelist, watchdir, ports, speeds, …).
  6. If you want to use the web-interface, copy its files: “cp -R web ~/Library/Application Support/transmission-daemon/”
  7. Re-start the daemon.

This worked well for me and I’m quite impressed with both the web-interface and Transmission itself.

    Hello, Im trying to build it into OSX too, but having the following problem:

    Undefined symbols for architecture x86_64:
    “_libiconv_open”, referenced from:
    _tr_utf8clean in libtransmission.a(utils.o)
    “_libiconv”, referenced from:
    _tr_utf8clean in libtransmission.a(utils.o)
    “_libiconv_close”, referenced from:
    _tr_utf8clean in libtransmission.a(utils.o)
    ld: symbol(s) not found for architecture x86_64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

    Any suggestion?
    Thanks

    And just to complement,
    to use the web you should copy it to
    “cp -R web ~/Library/Application Support/transmission-daemon/web”

    Works in pkgsrc on x64/Mountain Lion if you edit the ./configure file and just remove the lines around 19900 that quit if no MacOSX10.5 SDK. It fails the build … but daemon, cli and remote are all functional and can be taken from their folders manually.
