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? ---- Terminal Log ---------------------------------- Current step: (gr-baz :: make) make(’\n make -j4\n’, ‘\n make -j$makewidth\n’)(’\n make -j4\n’, ‘\n make -j4\n’) bash exec (/home/doug/pybombs/src/gr-baz/build):: make -j4 [0%] Built target baz\_swig\_swig\_doc [5%] Built target pygen\_python\_beed0 [7%] Built target \_baz\_swig\_swig\_tag [82%] Built target gnuradio-baz [84%] [87%] Swig source Swig source/home/doug/pybombs/src/gr-baz/swig/baz\_swig.i:3: Error: Unable to find ‘gnuradio.i’ /home/doug/pybombs/src/gr-baz/swig/baz\_swig.i:3: Error: Unable to find ‘gnuradio.i’ make[2]: \*\*\* [swig/baz\_swigPYTHON\_wrap.cxx] Error 1 make[1]: \*\*\* [swig/CMakeFiles/\_baz\_swig.dir/all] Error 2 make[1]: \*\*\* Waiting for unfinished jobs… make[2]: \*\*\* [swig/baz\_swigPYTHON\_wrap.cxx] Error 1 make[1]: \*\*\* [swig/CMakeFiles/pygen\_swig\_ae455.dir/all] Error 2 make: \*\*\* [all] Error 2 ERROR:root:PyBOMBS Make step failed for package (gr-baz) please see bash output above for a reason (hint: look for the word Error) doug@doug-GA-880GA-UD3H:~/pybombs$ ---

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. Tom ---

It looks like gr-baz updated it swig/CMakeLists.txt file and hard coded the path /usr/local/include/gnuradio/swig into it (line 35). But it should be set to ${GNURADIO\_RUNTIME\_INCLUDE\_DIRS}/gnuradio/swig, instead, in order to find it in other locations. See if making that change to your file in src/gr-baz/swig works. Tom ---

Looks like Balint’s doing the right thing on his github branch; pybombs’ recipe was pointing to the wrong repo. I’ll push a fix for this soon. Tom
