FWIW
Getting this on an older ubuntu (10.10) box, trying to compile from a cloned uhd git repo (which should be current as of today)
/home/mhp/uhd/host/utils/b2xx_fx3_utils.cpp: In function ‘int32_t main(int32_t, char**)’:
/home/mhp/uhd/host/utils/b2xx_fx3_utils.cpp:546: error: ‘struct std::basic_string<char,
std::char_traits<char>, std::allocator<char> >’ has no member named ‘string’
This is no big deal, I'm using a vintage-2010 USRP1, so I deleted the relevant line from CMakeLists.txt and reran cmake - all is clean now
