Comment:

 The first error in the log:
 {{{
 :info:build g2clib.c:1802:18: error: implicit declaration of function
 'g2_unpack1' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
 :info:build   __pyx_v_ierr = g2_unpack1(__pyx_v_cgrib, (&__pyx_v_iofst),
 (&__pyx_v_ids), (&__pyx_v_idslen));
 :info:build                  ^
 }}}
 So this is the well-known implicit function problem with Xcode 12 and
 later that will need to be fixed in the usual way. (Declare a function
 before you use it.)
