Code::Blocks

GNU Radio
1

Greetings everybody,

I have been using Code::Blocks IDE for a while. And I have tried to link
GnuRadio in Code:Blocks,
but I have not found any “.so” file in Ubuntu, although I have searched
via terminal with the command
“locate”.

I have read the tutorial in the web
page:http://gnuradio.org/redmine/projects/gnuradio/wiki/UsingCB&
http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules

I would like to ask you, if it would be possible to link GnuRadio
libraries in Code::Blocks IDE with
a file with extension “.so” ?

I would be gald if you could reply my email.

Thanks in advance,
Abdullah

Greetins everybody,

In my previous message, I said I had found no no .so file :).

I would like to ask you, especially to use usb/ethernet communication
functions of gnuradio,
which .so file I would need to link in Code::Blocks.

Thanks in advance,
Abdullah

Hi Abdullah,

Now I’m even more confused.
GNU Radio has no USB or Ethernet functionality at all (It has network
blocks, but they don’t have anything to do with ethernet level – they
just use your operation system’s sockets and don’t care about ethernet
at all).

Modern GNU Radio builds are split up in several libraries
(gnuradio-runtime, gnuradio-audio,…). You can usually find these
using “pkg-config --libs gnuradio-runtime”

So, but one step back:
What do you want to do? Build an out-of-tree module? In that case,
Code::blocks should work fine with the CMake build system which is
usually used to build such modules. That will find the necessary
libraries, linker options and so on for you.

Linking against a shared library alone does not really help you, you
need to know which symbols are in that library. You usually do that by
including specific .h describing the functionality. If you know what
headers you want, you usually know which library to link against.

Greetings,
Marcus

Dear Marcus,

Firstly thank you for your time.

I want to use gnuradio with not only USRP kits but also other kind of
devices which are
connected via USBport or ethernet. I have developed python programs
using gnuradio,
but currently I am required to use C++, and I prefer to use
Code::Blocks.

I have taken a look at the gnuradio files installed in a bit more
details and seen I could use lots
of gnuradio libraries by providing the link directory of the related .so
files and header files.

But I have not seen any .so file related to uhd files of gnuradio. By
the way, if I am not wrong,
for example for an audio device which is connected via USB port could be
accessible by
using gnuradio-audio sink/source files.

Thank you,
Abdullah

… as long as you know how to use the functionality within, yes.
But with only the library file, your compiler can’t say how the
functions you want to use look like.

However, to repeat: GNU Radio has no functionality to talk to any
device. It wraps these functionalities offered by hardware drivers
such as UHD (in the USRP case) or alsa (in the funcube
dongle/soundcard case). If you have a USB device that’s not covered by
the code supplied with GNU Radio you’ll need either another GNU Radio
module to talk to these devices (e.g. osmosdr) or need to write your
own driver.

When you developed python programs, you most probably did this in an
out-of-tree module, didn’t you?
That out-of-tree module has a build system based on CMake.
You should use that, it sets library paths, include directories, cares
for correct linking and installation and so on.
CMake is nicely integrated in Code::Blocks. You should not manually
specify the library to link against but let the Build System figure
that out for you.

Marcus

Dear Marcus,

When I used python, I followed gr-extras and developed my own blocks.

I looked at gr-audio, and saw that it uses alsa, which probably
prohibited my program, in which I used libusb,

to access my audio device for isochronous data acquisition; because I
have taken LIBUSB_ERROR_IO…anyway…

I will probably use asoundlib.h,

, to acquire data; gnuradio would be useful especially with osmosdr like
devices, but if I could
access my audio device and other connected devices such as camera etc.
gnuradio would be the best option

probably for a PC based application; at least I am more familiar with
gnuradio.

Thanks,
Abdullah

Dear Marcus,

I have found libgnuradio-runtime.so file, I guess this will allow me to
use entire gnuradio functionality in Code::Blocks.

Thank you,
Abdullah
