Re: [Discuss-gnuradio] gr-radar make problem

[Marcus Müller]

Hi Stefan,

don't think this is the Boost version at all; the error warning really,
out of nowhere, just suggest that "boost::str()" might be an alternative
to the "d_metadata_rx.strerror()" method, which wasn't found.

That method wasn't added befor UHD 3.7.0¹, and my guess is that it's not
Boost making a problem, but an old version of UHD?

One thing I don't understand is that you said old Boost versions didn't
contain strerror; as far as I know, that a libc function, and since
we're doing C++, you should always find that in the std:: namespace by
using #include <cstring>, right?

Cheers,
Marcus

¹ Just that no one thinks I know the UHD git logs from heart: I used 
"git log -p host/include/uhd/types/metadata.hpp" , searched for
'^\+.*strerror', and used the commit ID with "git describe ${commit}".
