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/UsingCB&) [http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules](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.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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.

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 On Sunday, April 13, 2014 2:21 AM, Marcus M.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 … 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.

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, [http://www.linuxdevcenter.com/pub/a/linux/2007/08/02/an-introduction-to-linux-audio.html?page=2](http://www.linuxdevcenter.com/pub/a/linux/2007/08/02/an-introduction-to-linux-audio.html?page=2) , 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.
