Hi,

I am trying to compile OVS(master branch) via gcc 6.5.0, but there is gcc 
option error.
gcc: error: unrecognized command line option '-Wmultistatement-macros'; did you 
mean '-Wunused-macros'?

My question is which versions of GCC are supported by OVS. Is it a bug of OVS 
compiling? The compiling output is attached.


gcc -v
