RE: [Discuss-gnuradio] question on howto write a new block
hi Eric:
I had install the gnuradio-3.3.0,and use the
create-gnuradio-out-of-tree-projec test_example command to make a new block
which is named test_example,
then I changed the test_example_square_ff.h/cc to test_example_add_ff.h/cc,and
I also changed other files like Makefile.am.Then I use the following command to
install the new block:
./bootstrap
./configure
./make
./sudo make install
After that I thought I had installed the new block,then I write a simple
file to test it which is named test.py.but after I run the file ,I got the
following errors:
File ./test.py, line 4, in module
import test_example
File /usr/local/lib/python2.6/dist-packages/test_example/__init__.py, line
40, in module
from test_example_swig import *
File
/usr/local/lib/python2.6/dist-packages/test_example/test_example_swig.py,
line 24, in module
_test_example_swig = swig_import_helper()
File
/usr/local/lib/python2.6/dist-packages/test_example/test_example_swig.py,
line 20, in swig_import_helper
_mod = imp.load_module('_test_example_swig', fp, pathname, description)
ImportError: libgnuradio-test_example.so.0: cannot open shared object file: No
such file or directory
Can you tell me the reason of these errors? Thank you in advance.

hi all:
I am writing a new simple signal processing block following the

howto_add_ff.h and howto_add_ff.cc file under /gnuradio-3.2.2/
gr-howto-write-a-block-3.2.2/src/lib.Then I modified howto.i and
Makefile.am in
the same directory.
After that I run the following command under the directory
/gnuradio-3.2.2/
gr-howto-write-a-block-3.2.2:
./bootstrap

make
Then I got a error said thers is no rules for all-am to creat the
required target howto_add_ff.h.STOP.( I translate the error into
english
beacause I do no use engliah as the language of my Ununtu).
Can anyone tell me how to fix it?
You've probably not adapted the Makefiles properly.
Have a look where howto_square_ff.* is referenced (it's a couple of
places).
I recommend using gr_modtool.py (you can get it from
https://www.cgran.org/wiki/devtools), this automatically does all the
edits for you.
Cheers,
MB
I'd also suggest starting with 3.3.0 (or git master) instead of 3.2.2, and
use the
$ create-gnuradio-out-of-tree-project my-module-name
command to get you started.
