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?
