Tian,

Disable logging and debug in the GRC flowgraph. See if this solves the
problem. For reference, see [1].

Make sure logging is disabled on ALL blocks. I haven’t seen that
libstdcxx error before, but I do have the segfaults with the logging in
Ubuntu 15.04 with pybombs install.

Hi,

I just replied on github

It would be great if you could try what I suggest there.

Best,
Bastian

Hi,

yes, this is how it is supposed to look. But please read the posts at
the bottom of the thread. Actually, it should work without modifications
now.

Best,
Bastian

Hi Bastian,

Thanks!

The file ( ofdm_decode_signal.cc) I have downloaded is still written as
(Yes–no mylog(temp) now):

“mylog(boost::format(“encoding: %1% - length: %2% - symbols: %3%”)
% d_encoding % d_len % d_copy_symbols);”

To make it work, I still need change it to
"std::string temp = (boost::format(“encoding: %1% - length: %2% -
symbols: %3%”)
% d_encoding % d_len % d_copy_symbols).str();

Actually, I don’t really understand the difference between these two.
What
does this change mean? Does the problem relate to log4cpp?

This was suggested to debug the problem, not as a fix.

The problem is described in the issue you referenced (scroll down) and
hopefully fixed by this commit

Please update the module with git.

Bastian
