[ovs-discuss] OVS compiling issue(gcc version 6.5.0 )

[Yanqin Wei (Arm Technology China)]

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.
