I am trying to install gnuradio onto a Centos 7 box and am having more and more issues with packages that use c++11 commands. For some of the packages, I add the line: CMAKE_CXX_FLAGS "-std=c++11" to the module's CMakeLists.txt file. The issue is that that requires a fetch, the mod, and then a rebuild. This worked OK with it was just gqrx I was doing it for, but now I need it for other modules it appears, and so I am trying to find a more elegant solution that covers everything that is built via a pybombs install gnuradio command (like gr-blocks, which I can't use this trick for). If I understand the problem correctly, Ubuntu uses new enough tools to realize that it needs to use the c++11 version (or newer I assume) to build since it is needed. It seems like even though Centos 7 has the c++11 capability, it does not smartly trying to use it, and must be directed to for the installs to work. Is there something I can do at an upper level to make things happy on an install?
