Right now, I'm using Strake's patch and compiling musl with -Os. Of course, these aren't going to be enough to make busybox allyesconfig work right; I also ran into the following issues building busybox: -<sys/personality.h> needs the macros from <linux/personality.h> (for setarch) -A few cases of using extra headers that break the busybox build: <net/if_slip.h> can be changed to <linux/if_slip.h> <net/if_packet.h> is included (needlessly for musl) in networking/libiproute/iplink.c; this header is roughly the macros from <sys/socket.h> + struct sockaddr_pkt <netinet/ether.h> is used in arp and zcip -CONFIG_COMPAT_EXTRA turns on use of glibc regex.h extensions in grep. -Of course, vi still uses glibc regexes if you enable search and replace. > Rich HTH, Isaac Dunham
