Re: [Discuss-gnuradio] Making and Installing a New Block
I'm running the python code squaredaudio.py in its own directory. Make install with the additional files is what breaks the entire howto module. The only thing that changes between when squaredaudio.py runs and doesn't are those files I attached and then running ./configure, make, make install. Returning the build tree back to the way it came in the tar.gz file and then going through ./configure, make, make install fixes the howto module so that squaredaudio.py runs. Of course this means that howto_square3_ff isn't available. I hope I replied to the list correctly this time.

Be sure to NOT be in the directory containing the code. This avoid potential problems with how python resolves imported files. Have your done a make install? Note that the error message above indicates that it's looking in the installed path. If you haven't installed the code yet with make install it'll be pulling in the old libs. Let me know if this helps. Eric ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

[Discuss-gnuradio] Problem Making and Installing New Block
I'm trying to write a new block called howto_file_modulator_f to be used in gnu radio. I'm new to programming using autotools and I believe this is where I'm having problems. I found a tutorial for writing a new block here: http://www.nd.edu/~jnl/sdr/docs/tutorials/11.html. I am also using How to Write a Signal Processing Block article on the Gnu Radio site. I'm using Gnu Radio version 3.0.4 on a machine running Fedora 7. So first I extracted the tar file into my home directory /home/franklin/gr-howto-write-a-block-3.0.4/. I will call this topdir. I wrote the c++ .h and .cc files and put them in the topdir/src/lib folder. I modified the howto.i file by putting #include howto_file_modulator_f.h in the include section and added this at the end of the file: GR_SWIG_BLOCK_MAGIC(howto,file_modulator_f.h); howto_file_modulator_f_sptr howto_make_file_modulator_f (); I also added a class declaration with the public member functions, the private constructor, and public destructor. Then I modifed topdir/src/lib/Makefile.am. howto_file_modulator_f.cc was added to _howto_la_SOURCES list. howto_file_modulator_f.h was added to the grinclude_HEADERS list. topdir/configure.ac and topdir/src/python/Makefile.am were not modified. Configure.ac was left alone because I was still installing everything under the howto module. The last Makefile.am was not modified because I haven't created any quality assurance test code yet. ./configure still seems to work find but I get a long list of errors when I try to make the block. I have attached a file with the command line output. Any idea on what I forgot to do or didn't do right? I can send the c++ code if it will be helpful in trouble shooting this.
