Okay, the title is a bit of a lie; the port succeeds in building and installing.
I'm working on a new port for transcode [1] and am running into a problem. The port will be pulling HEAD from cvs so I am fully aware that the problem I am seeing right now could be related to instability in the trunk.
Again, I have the port successfully building and installing. However, executing the binary to do even simple operations results in a hang. The weird thing is that the command will execute to completion and then hang on exit.
For example, if I execute 'transcode --version' it successfully prints its version info and then hangs. I can also issue a command to transcode a movie from mpeg2 to h.264 which results in a good clean file, but it hangs during exit.
Is there a tracing facility on OSX I can use to track down this problem? Most of my coding experience is IOKit in-kernel so I'm not really good at this userland stuff. Thanks for any help or pointers.
For anyone wondering, the answers were 'ktrace,' 'kdump,' and 'gdb.' cr
