[Discuss-gnuradio] segmentation fault with current gnuradio version on USRP1

[Jiri Pittner]

Hello,

I would like to ask for an advice - I have troubles running current
gnuradio git version with USRP1 using UHD.

I have installed UHD drivers with downloaded firmware and FPGA images and 
compiled the host code;  uhd_usrp_probe seems to work: 
linux; GNU C++ version 4.5.3; Boost_104700; UHD_003.003.002-unknown

-- Using FPGA clock rate of 64.000000MHz...

Then I installed gnuradio from git clone and configured it as:
./configure  --enable-gr-uhd --enable-gr-noaa --enable-usrp2 --enable-usrp  
--enable-gr-usrp --enable-grc --enable-gr-audio-alsa  --enable-gr-trellis  
--disable-volk
I had to disable volk due to compilation errors (some 32-64 bit code mismatch I 
guess).
It seems that old USRP (non-UHD) support has been already removed and when I 
trysome UHD example, it always coredumps:

On the other hand, I have also funcube-dongle, and the same version of gnuradio 
works fine with that device.
I have python 2.7, boost 1.42.0 (with both 1.46 and 1.47 I got compilation 
errors in gnuradio), gcc (Gentoo 4.5.3-r1 p1.0, pie-0.4.5) 4.5.3,
running 3.1.5-gentoo #2 SMP on  x86_64 Intel(R) Core(TM) i7 CPU Q 740 @ 1.73GHz 
HP 8540w laptop.

I tried also to install gnuradio-3.4.2: this has still the old USRP support, 
which works fine, but UHD segfaults as well (and funcube does not work).

Do you have any idea what to do?
Thanks very much for help.
Best regards,
