At the beginning of the GNURadio install, I took all of the defaults, so it was put into
Home/doug/target/. I am still feeling my way around Linux. Can you tell me where I need to be
looking to insert the path to gnuradio.i?
Thanks for the snappy reply,

Yesterday, I built a new Ubuntu 14.04, installed the new GNURadio 3.7.4 and installed gr-op25. This all works, except that the gr-baz Op25 Decoder block, and other blocks, have unresolved baz imports. I ran ./pybombs install gr-baz and it ended with errors as shown in the Terminal log below. The error appears to be that it cannot find gnuradio.i.
I have built this system before, with GNURadio 3.7.2 and have the same error. I have done lots of searches and have reported this problem on op25-dev, but have had no answers. Can someone please help?

It's likely that the problem is just a missing swig include directory. Like gcc, you can tell swig other directories to look into for header and interface files. We set these up in GNU Radio using the SET(GR_SWIG_INCLUDE_DIRS) variable and passing it information about the location of the .i files for the required components.
My guess is that your gnuradio is installed into a "non-standard" directory, that is, one that swig doesn't look for by default, and that gr-baz isn't finding it and/or isn't passing the directory to swig. You'll find the gnuradio.i file in $prefix/include/gnuradio/swig, where $prefix is whatever directory you installed GNU Radio into, like /usr or /usr/local.
This isn't exactly a fix for your problem; I'd have to look at gr-baz to figure out why it's not using it, but hopefully it's enough info for you to work off of.
