Re: [Discuss-gnuradio] UHD won't work with GRC

[Fabian Klaes]

I first tried make distclean and the installation went fine, but when I tried to start the GRC, following window showed up: http://tinypic.com/r/dq671d/7 containing the error message "Cannot import gnuradio. Are your PHYTONPATH and LD_LIBRARY_PATH set correctly?"

I then tried git clean -dfx and rebuilding from scratch (for UHD and GNUradio).
Installation for UHD (worked):

git clone git://code.ettus.com/ettus/uhd.git
cd uhd/host
mkdir build
cmake -DCMAKE_INSTALL_PREFIX=/opt/uhd ../

make
make test
sudo make install

PATH=$PATH:/opt/uhd/bin

uhd_find_devices and uhd_usrp_probe works fine now, so i figured that the installation of UHD was successfull

Installation for GNUradio (error at ./configure):

git clone git://gnuradio.org/gnuradio.git
git branch --track next origin/next
git checkout next
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH} #just to be sure ...
BOOST_PREFIX=/opt/boost_1_37_0 #echo $BOOST_PREFIX returned nothing in the first place, so i figured it could help
LD_LIBRARY_PATH=/home/fs/gnuradio-git/uhd/host/build/lib/:/opt/uhd/lib/:/opt/boost_1_37_0/lib

#I also put both uhd paths in ld.so.conf and ran sudo ldconfig, but it didn't help

./bootstrap
./configure --with-boost=$BOOST_PREFIX  --enable-gr-uhd

Now following error showed up:
checking for UHD... no
gr-uhd requires libuhd 2.x.x
configure: error: Component gr-uhd has errors; stopping.

I did: find |grep libuhd and got:
./home/fs/gnuradio-git/uhd/host/build/lib/libuhd.so
./home/fs/gnuradio-git/uhd/host/build/lib/libuhd.so.002
./usr/local/lib/libuhd.so
./opt/uhd/lib/libuhd.so
./opt/uhd/lib/libuhd.so.002

so I added /opt/uhd/lib/ and /home/fs/gnuradio-git/uhd/host/build/lib/ to ld.so.conf and ran sudo ldconfig (as said above). I then also tried to set LD_LIBRARY_PATH (see above again) but still the same error.
I also tried to git clone from http://gnuradio.org/git/gnuradio.git (described in [1]) instead of git://gnuradio.org/gnuradio.git (described in [2])

I don't know what to do next and would appreciate any help (again). I would be really happy if we could get this going.

Sometimes autotools gets confused when there are many changes to the
build system. Try make distclean, and if not working: git clean -dfx
(wipes everything). and rebuild from scratch.
