A last(?) hurdle?

After updating a series of programs, I lost the use of gnuradio.
Several problems have been solved, and I have recompiled gr+grc,
and it is running again.

When I execute a fairly simple program, I get the following error:

File “”, line 1, in
File
“/usr/local/lib64/python2.6/site-packages/gnuradio/wxgui/forms/init.py”,
line 36, in from forms import
File

line 14774, in from _misc import *
File
“/usr/lib64/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/_misc.py”,
line 4, in import misc

ImportError:
/usr/lib64/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/misc.so:
symbol _ZN7wxSound6CreateEiPKh, version WXU_2.8 not defined in file
libwx_gtk2u_adv-2.8.so.0 with link time reference

I recompiled wxpython, wxgtk, checked dependencies:

<ldd /usr/lib64/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/misc.so
| grep libwx_gtk2u_ad
libwx_gtk2u_adv-2.8.so.0 => /usr/lib64/libwx_gtk2u_adv-2.8.so.0
(0x00007f33cdded000)

Checked if the symbol is in the libwx_gtk2u_adv-2.8.so.0 library:

readelf -W -s /usr/lib64/libwx_gtk2u_adv-2.8.so | grep
_ZN7wxSound6CreateEiPKh
682: 00000000000b1440 133 FUNC GLOBAL DEFAULT 11
[email protected]@WXU_2.8.11
854: 00000000000b1440 133 FUNC GLOBAL DEFAULT 11
_ZN7wxSound6CreateEiPKh

Is it the .11 in the 2.8.11 reference?

Any suggestions? (Lots of similar cases on the 'net, no solutions
found…)

TIA,
John

sudo rm /usr/local/lib64/libgnuradio*

Then re-do your gnuradio
build and install

Then “sudo ldconfig”

Thanks Martin, but no luck there. Exactly the same error.

Martin, though I’m far from being an experienced Python programmer,
please note that the error seems to be between non-gnuradio components:

ImportError:
/usr/lib64/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/misc.so:
symbol _ZN7wxSound6CreateEiPKh, version WXU_2.8 not defined in file
libwx_gtk2u_adv-2.8.so.0 with link time reference

(even though the original call did come from GRC, of course)

Ah, I missed that. Probably your wxPython stuff is out of date.

You could try re-running the “build-gnuradio” script if you’re on
Ubuntu or Fedora.

Thanks Martin, but to be honest, I’ve been called much worse :slight_smile:

Thanks Martin,

Yep, I’ll try to call Martin Marcus in the future, the problem was that
I was relying on my memory, which lately got somewhat warbled (more than
usual) by this resistant bug. Sorry for the confusion!
