[Discuss-gnuradio] Trouble getting GNUradio/UHD working (with PyBombs)

[Jeroen Boschma]

Hi all,

I picekd up GNU Radio again and tried to get a simple plain C++ project 
working, but no success..... Details below, hopefully somebody can set 
my nose in the right direction.

What I want to do
========================================
I want to do some C++ coding outside Companion, so I have C++ with code 
like:

---------------------------------------
int main()
....
gr::top_block_sptr tb = gr::make_top_block("USRP_framework");
....
gr::uhd::usrp_source::sptr usrp_source = 
gr::uhd::usrp_source::make(device_addr, uhd::stream_args_t("fc32"));
....
tb->connect(usrp_source, 0, custom_processor, 0);
....
---------------------------------------

So I want to use the GNU radio framework, and also have direct control 
over the USRP. I use a very simple and dirty makefile, to keep as much 
complexity out of this, the goal is just to get it working:

---------------------------------------
CC     = g++
LIB    = -lglut -lGLU -lGL -lgnuradio-blocks -lgnuradio-fft 
-lgnuradio-pmt -lgnuradio-runtime -lgnuradio-uhd -lboost_system 
-lboost_thread -luhd
INCDIR = -I matplotpp
ALIB   = matplotpp/matplotpp.a

USRP_framework: USRP_framework.cc

    $(CC) $(INCDIR) -o USRP_framework USRP_framework.cc $(ALIB) $(LIB)
---------------------------------------

My intiial steps:

1) I made a fresh Ubuntu install
2) installed git
3) got PyBombs
4) installed GNUradio using PyBombs. As far as I can see, it also 
installed UHD directly since it moved in PyBombs to 'installed hardware 
apps' and cannot be chosen to install anymore.

No problems thusfar.

What went wrong during 'make'
========================================
1) The GNU-radio includes were not found, so I installed gnuradio-dev 
using 'apt-get'.
2) Then UHD includes were not found, so I filled /usr/include/uhd with 
the include files by hand (downloaded them).
3) Then the makefile tells me that 'luhd' was not found

Anybody an idea what my next step should be to get this very simple 
framework working? If PyBombs already installed UHD, why is there no 
libuhd.so file on the HD? There is a libuhd.so.003 and a 
libuhd.so.003.005 ....

One of the reasons I started all over again (I had a GRC installation 
previously) is that a previous attempt gave me errors regarding ABI 
versions mismatches between GNUradio and UHD. So they should be build 
'simultaneously' using exact the same resources I guess...

Best regards,
