your kernel headers are too old. The "linux/" is obviously linux specific, the "net/" include is the proper one. $ grep -r ARPHRD_INFINIBAND build_m68k_nommu/staging_dir/usr/include/ build_m68k_nommu/staging_dir/usr/include/net/if_arp.h:#define ARPHRD_INFINIBAND 32 /* InfiniBand. */ build_m68k_nommu/staging_dir/usr/include/linux/if_arp.h:#define ARPHRD_INFINIBAND 32 /* InfiniBand */ > >Q2 : What macro values can I set while I invoke make to compile busybox? >(e.g. CROSS_COMPILE, V, ...?) Any list? Could they be listed in "make help"? You can set V=1 if you like.
