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

[Fabian Klaes]

First of all, thank you for your advice.
Now i encountered another Problem:
At first i updated UHD via git pull, then i did (from the "build" directory)

cmake ../
make
make test
sudo make install

everything works fine (well, not everything, but at least the installation ;-) ).

Then i went to my gnuradio directory and did:

git checkout next
git clean -xf
git pull

# GNU Radio release is now v3.3.1git-865-gd429522b instead of v3.3.1git-865-gd429522, but this should be newer

export LD_LIBRARY_PATH=$BOOST_PREFIX/lib
./bootstrap
./configure --with-boost=$BOOST_PREFIX

# ./configure now includes gr-uhd, so this problem is solved. Thanks again!

make

Then, make fails with:

Making install in swig
make[5]: Betrete Verzeichnis '/home/fs/gnuradio-git/gnuradio/usrp/host/swig'

make[6]: Betrete Verzeichnis '/home/fs/gnuradio-git/gnuradio/usrp/host/swig'

Sorry, that it's in german, heres the translation:
Betrete Verzeichnis = Entering directory
Verlasse Verzeichnis = Leaving directory
Fehler = Error

And the (probably) critical part causing the error:
make[6]: *** Keine Regel vorhanden, um das Target »usrp_prims.cc«, 
  benötigt von »_usrp_prims_la-usrp_prims.lo«, zu erstellen.  Schluss.
make[6]: *** No Rule given, for making Target »usrp_prims.cc«, 
  needed by »_usrp_prims_la-usrp_prims.lo«.  Ending.


If you (or anyone else) got another hint on how to solve this i would be really glad.

Thanks again and in advance

Fabian

The merging of next -> master was announced for UHD, not for GNU
Radio. You need:
UHD master branch
GNU Radio next branch
see http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki

This number is for the master branch. The correct revision id for the
next branch is (was earlier today) v3.3.1git-865-gd429522

Aside from using the correct GNU Radio branch (next) you also need to
install UHD first, otherwise the GNU Radio configure script will not
detect it and will skip it.
