Problems installing/compiling gnuradio-companion in Ubuntu 12.04

GNU Radio

Hello,

did not find in the wiki, did google but not found any special
information… I am also new to gnuradio, so maybe I just don’t yet know
the right place where to look…

I am trying to install gnuradio and gnuradio-companion in Ubuntu 12.04.

I therefore downloaded a ISO CD and freshly installed it on a separate
laptop.
“sudo apt-install gnuradio gnuradio-companion” does not work initially,
it says that these packages are not available.
just after adding
deb http://gnuradio.org/ubuntuunstable main
deb-src http://gnuradio.org/ubuntuunstable main

to /etc/apt/sources.list file and updating/upgrading it shows those two
package.

However, I am getting an error when trying to install
gnuradio-companion:
Die folgenden Pakete haben unerfllte Abhngigkeiten:
gnuradio-companion : Hngt ab von: python (< 2.7) aber 2.7.3-0ubuntu2
soll installiert werden
E: Probleme knnen nicht korrigiert werden, Sie haben zurckgehaltene
defekte Pakete.
In english this means that there is a dependency to python<2.7 but I
have 2.7.3 installed.

— snip —

ok, what else? Install it using the famous skript…
Works insofar but it also gives a linker error:

Linking CXX shared module _pmt_swig.so
/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation
R_X86_64_32S against `_Py_NotImplementedStruct’ can not be used when
making a shared object; recompile with -fPIC

make[1]: *** [gruel/src/swig/CMakeFiles/_pmt_swig.dir/all] Fehler 2
make: *** [all] Fehler 2
make failed

Is there any idea what to do?

Thanks a lot in advance (really!!!)

Some more system information:

My Linux is cat < /etc/issue Ubuntu 12.04 LTS \n \l
Kernel uname -a Linux L8410 3.2.0-24-generic #39-Ubuntu SMP Mon May 21
16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Means I have a Fujitsu-Siemens Lifebook E8410 dual core 2,4GHz with 64 Bit
installation
but I have also had the same error with a 32bit installation.

Python version:
python --version
Python 2.7.3

Guenter,

It looks like you have build Python yourself (I’m not sure why else it
would be installed into /usr/local). With Ubuntu, just ‘sudo apt-get
install python’ and use the default installation.

The next best thing, if build-gnuradio still isn’t working for you,
use the install instructions for Ubuntu found here:
http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide

Hope this helps.

Hello Tom,

I got a gnuradio compiled in a VM with 32bit Linux meanwhile, but this
is not the target that I am looking for. I want it on my 64bit Linux, as
stated above, if possible,

and here, following the build instructions, I am still getting the error
when linking:
/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation
R_X86_64_32S against `_Py_NotImplementedStruct’ can not be used when
making a shared object; recompile with -fPIC
/usr/local/lib/libpython2.7.a: could not read symbols: Bad value

Cheers, Gnter
