Re: macOS building issues after dc9eba0760dedcd3d042a408e715b38ac2222aa3

[Chun Tian (binghe)]

Now I modified configure.in and re-generated the "configure" (by the
same version of autoconf), but during the building process I saw another
error message regarding the missing of gmp.h:

But this time I can't figure out where to fix...
