Hi Folks
Recent macOS / xcode update broke the version of clang in conda so I can no longer build (SCons decides that the compilers don’t support C++11)
I can build just fine, and everything works and all the tests pass
However if I try and recompile anything SCons swears at me and dies as it decides that the perfectly valid C++11 compilers I have don’t compile C++11 because … some reason which makes no sense to me. Here is content of config.log
Grey-Area build :( $ cat config.log

clang: error: no input files
Key point is this: I can blow away the build directory and it all compiles correctly, but if I touch a file and type make I get build failures as so
Has anyone a clue about this? Should I add an issue on GitHub?
Thanks Graeme
