How to add c++ modules after gnuradio-3.2.2. binary installation?

GNU Radio

Hi

I installed gnuradio-3.2.2. Binary package in Ubuntu 9.04.
It was not flexible to include new c++ files
(I could not find bootstrap, configure.ac files etc in
usr/share/gnuradio
installation directory).

I then downloaded gnuradio-3.2.2.tar.gz and
gr-howto-write-a-block-3.2.2.tar.gz files and unzipped them in my home
folder,
and
gr-howto-write-a-block-3.2.2 was included as a subdirectory in the
gnuradio-3.2.2 directory.

I used installation commands ./bootstrap, ./configure, make, sudo
make
install
in gnuradio-3.2.2 directory, and no error was reported. I then tried to
run
file
qa_howto.py (after chmod +x qa* ) in directory
gr-howto-write-a-block-3.2.2/src/python, as follows:

./qa_howto.py

Error was reported that “in import howto”, “howto” module could not be
recognized.
I tried many other means, including modifying makefile.am in several
directories,
and
using installation ./bootstrap, ./configure, make, sudo make install
in gr-howto-write-a-block-3.2.2 directory. No error was reported.

But still
./qa_howto.py
could not work.

Questions:

  1. How can I make this work?
  2. How can I add new functions and modules using c++ files based on
    gnuradio-3.2.2 binary installation?

Thank you.

Jack

Hi,

I don’t think gr-howto-write-a-block is part of the normal build
environment
– there’s a separate one within this directory.

Try running:
./bootstrap
./configure
make
make check
sudo make install

from inside this directory (i.e gnuradio/gr-howto-write-a-block)

You might run into some weird issues if you’ve installed the binary
packages
before compiling from source (unless youve changed the prefix) as it’s
possible you’ve got two copies of gnuradio - Make sure you’ve removed
the
old binary installs.

I add new C++ blocks into my own module by following the instructions at
http://www.mail-archive.com/[email protected]/msg00123.html (and a
bit
of trial and error whilst I got the hang of automake etc)

There might be an easier way than this however!

Cheers,

Tim

Hi, Tim

I Tried running:
./bootstrap
./configure
make
make check
sudo make install

from inside this directory (i.e gnuradio/gr-howto-write-a-block)

But the problem was not solved for qa_howto.py.

I also ran
make distclean,
in gnuradio-3.2.2 source installation directory,
but seems I didn’t remove binary installation.

  1. Can you please tell me how to remove former binary installation?
    After cd
    /src/share/gnuradio, then I didn’t know what to do.
  2. How to change prefix to specify the installed GNU directory?

After fixing the howto modules, then I will check how to add new cc+
modules.

Thanks.
