Re: [Discuss-gnuradio] Best way to share/install hierarchical grc blocks?

I need to think about some of these ideas, but wanted to thank both of you for the replies. My inclination right now is to install the .py.xml into the grc installation-wide "blocks" directory, and the .py into the correct gr subdirectory for my additions,
and then have an install-time step that edits the .py.xml so that the execfile line points directly to that .py file. (I'm presuming that a hier-block .py.xml file, once installed in the "normal" place, won't try to mess with ~/.grc_gnuradio, but I haven't tried it yet.) I'm using the how-to-write-a-block framework, so the python install directory would be available to the Makefile in the build/grc directory (which right now has no build actions since it just is there for "make install")

Incidentally, I tried changing the execfile into "from dir import class", but it seemed to not quite produce the same state, in that I was not able to instantiate the module after that. But I may have just done something wrong and given up too early.

Hi,

I'm trying to figure out a good way to distribute some custom heir blocks that go with my low-level custom blocks I've written. The issue is that the xml and py files are both generated into my ~/.grc_gnuradio directory, and the xml files contain lines like

execfile("/Users/myname/.grc_gnuradio/file.py")

which obviously is not distributable. (Those lines get generated into any grc output files that use the block, so editing it at the point of use is not much of a solution.)

The obvious answer is to edit that line by hand, but the next problem is that I don't even know where the gnuradio directory is for other people (could be a different host platform, for instance). There also seems to be no "execfile search path" concept, which would allow me to perform some light editing of the xml file to remove the absolute path. So how do people share their created hierarchical blocks?

(I suppose the answer could be "give them my .grc_gnuradio files and tell them to edit all of the references", but that doesn't make for a nice delivery.)
