OK, I stupidly assumed things would be installed in the 'usual'
places... After changing the makefile and modifying /etc/ld.so.conf
things work good. Thanks!

Pybombs usually installs stuff in ~/target and adds a script there
called ~/target/setup_env.sh which sets up paths. You should try
running that before building gnuradio things after installing pybombs.
If the includes still aren't found try looking in ~/pybombs or
~/target for them. You should not have needed the apt-get lines after
successfully installing pybombs and should probably uninstall those
items.

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,
Jeroen Boschma
