Hmmm. That means I have to specify the directory users must start grc from to keep from erroring out?

This a very generic Linux thing.  Nothing to do with GRC or Gnu Radio specifically.  When you hand the operating system a relative path, it is
  interpreted in the context of the current directory.  That is uniformly true.

If that "doesn't work for you", you can always come up with a little wrapper script that places your user process in the desired directory before
  starting the actual thing you're wanting to run.

You're probably not running the script from where the .py is, but from where GRC started. Relative paths are relative to that folder.
That means that if you run gnuradio-companion from your home directory (which is probably the default when you just open it from some menu), then paths are relative to /home/user1.

Easy question here. I'm trying to use a relative path with file sink/source. It errors out with "can't open file".

I'm assuming the path is relative to the location of the .grc file location.

If the location of the .grc file was: /home/user1/proj1/devel/myfile.grc

And a data file was here: /home/user1/proj1/dat/datafile.dat

Then the path I use in file source is: ../dat/datafile.dat

What do I need to change to make this work?

Thanks,

Rich
