[Discuss-gnuradio] Compiling gnuradio from source on GENTOO Linux failed

[Meino . Cramer]

Hi,

I am trying to build gnuradio on a recent Gentoo system from
source. I tried to use emerge/portage for that, but it
fails in a configuration step.

The system:
Recent Gentoo Linux
gcc version 4.8.4 (Gentoo 4.8.4 p1.4, pie-0.6.1)
glibc-2.20-r2
CPU:AMD Phenom(tm) II X6 1090T Processor

The device I want to use as receiver is listed via 'lsusb -v'
like this:

I downloaded gnuradio-3.7.5 and followed the
instructions on the wiki.

The build-process ended without error as far
as I can tell (buildlog attached).

Running 'make test' sometimes reports 2 and sometimes
3 error on the identical build (testlog attached)

If I install gnuradio nontheless and starting gnuradio-companion
it shows a dialog displaying this:

----------------------------------------------------------
Cannot import gnuradio.

Is the python path environment variable set correctly?
    All OS: PYTHONPATH

Is the library path environment variable set correctly?
    Linux: LD_LIBRARY_PATH
    Windows: PATH
    MacOSX: DYLD_LIBRARY_PATH
----------------------------------------------------------


and after pressing CLOSE it ends.

I set PYTHONPATH to /usr/lib64/python2.7 and
added /usr/local/lib64 to ld.so.config but that
does not change anything. Even without setting PYTHONPATH 
explicitely no other python application shows problems...

I used 'strace' to trace the calls of gnuradio-companion
and subprocesses but found nothing which gives any further
informations to me.

I googled for the failed tests and build errors but
I either find nothing appropiate (exact searchh phrase) 
or much to much (loose search phrase). The list of 
open build problems seems also not to mention my case.

Since I am new to gnuradio and I am no native English speaker
I may not being /that/ successful in searching with the right
phrases...

How can I proceed from here to fix the above problems?

Thank you very much in advance for any help!

Best regards,
Meino
