Small question

GNU Radio
1

Hi all.

can you please tell me where to find the source c code of the signal
processing blocks which already installed in the OS.
my OS is Ubuntu 9.10 - the Karmic Koala -
I found the source in the downloaded file gnuradio-3.2.2.tar.gz in this
directory:
/gnuradio-core/src/lib/general/gr_bin_statistics_f.cc
but i cannot find the same directory in my OS.

sorry for the trivial question but I’m still new.

regards,

–

cc files do not get installed, what gets installed:

shared libraries (compiled and generated from the cc files)
header files for development

Hi all.

processing blocks which already installed in the OS.

The blocks are probably not installed in the kernel. :slight_smile: On my system
Ubuntu karmic they are compiled as object code and archived in a library
in
/usr/local/lib/libgnuradio*

my OS is Ubuntu 9.10 - the Karmic Koala -
I found the source in the downloaded file gnuradio-3.2.2.tar.gz in this
directory:
/gnuradio-core/src/lib/general/gr_bin_statistics_f.cc
but i cannot find the same directory in my OS.

There is a directory called /usr/local/src in the filesystem. Maybe
there?
Hm, what is it for?

In general, on Ubuntu, this should work to fetch the sources of
installed binaries:

sudo apt-get source gnuradio

It doesn’t seem to be working right now, however.

I just use the sources in gnuradio-3.2.2.tar.gz myself.

In that tarball you will find, for example:

./gnuradio-core/src/lib/general/gr_bin_statistics_f.cc

I want the source code so i can know what is the function of this class
“gr_bin_statistics_f.cc”. because in the API its not written clearly
just
like “control scanning and record frequency domain statistics”.
Thanks for the reply
