Problems building GNURadio on Ubuntu 12.04LTS

G’day,

I’ve downloaded today’s sources and tried to build GNURadio on Ubuntu
12.04LTS when I hit the following problem:

[ 85%] Built target pygen_gr_trellis_src_examples_python_cef97
[ 85%] Building CXX object
gr-uhd/lib/CMakeFiles/gnuradio-uhd.dir/gr_uhd_usrp_source.cc.o

error: uhd/config.hpp: No such file or directory
compilation terminated.

Searching the source tree, there indeed is no config.hpp. Is this file
generated during the configuration process?

I wonder how gnuradio got configured with uhd support? Thats actually
the one file the FindUHD.cmake looks for to confirm the header location:

FIND_PATH(
UHD_INCLUDE_DIRS
NAMES uhd/config.hpp
HINTS $ENV{UHD_DIR}/include
${PC_UHD_INCLUDEDIR}
PATHS /usr/local/include
/usr/include
)

Thats just the first header it encounters. Theres probably some
installation issue. Can you post the ls /include/uhd/*

I didn’t have uhd installed and hence /usr/{local,}/include/uhd don’t
exist.

Having said this, I had an older version installed, 3.5.2 if my memory
serves me correctly, which was de-installed prior to updating and
building the current source tree.

I’ve installed UHD and gnuradio builds fine.

Many thanks for your help and pointing me into the right direction.
