Hi everyone, I've run into this on every Ubuntu 16.04 box I've installed gnuradio and OOT modules on and Google doesn't seem to have a nice clean answer (the search answer is always add a compile flag) so I figured I'd ask the group.
When I build modules (gr-osmosdr in particular with libfreesrp support I run into this) on a fresh Ubuntu 16.04.2 LTS install, I run into a warning like this: "warning: non-static data member initializers only available with -std=c++11 or -std=gnu++11". Depending on the code it may produce errors on some lines preventing compilation. I know what causes it, the compiler is defaulting to something earlier than the c++11 standard (like C++99) with the Ubuntu repo gcc version (5.4) installed, so some of the syntax in the code is causing the warning. I can modify the CMake and add this to it "set (CMAKE_CXX_STANDARD 11)" and it builds after that, but my guess is that this builds on everyone else's Ubuntu without these modifications or the setting would be standard in the CMake files. What I'd really like to do is tell the compiler to default to -std=C++11 even if it's not explicitly provided as a compile flag, but again if everyone were running into it I think it would have been fixed another way. If I do the same build on a standard debian build with gcc 6.3 it builds clean so it's definitely a default standard issue for compilers on Ubuntu 16.04. Does anyone have any insight/suggestions?
