------- Comment #8 from huamama at gmail dot com 2007-11-21 10:24 ------- Thanks. The complie flag in the Makefile of Busybox is "/opt/arm/bin/arm-linux-gcc -I/home/mahua/opt/test/busybox-1.1.3/include -I/home/mahua/opt/test/busybox-1.1.3/include -I/home/mahua/opt/test/busybox-1.1.3/libbb -funsigned-char -Wall -Wstrict-prototypes -Wshadow -Os -funit-at-a-time -fstrict-aliasing -fomit-frame-pointer -D_GNU_SOURCE -DNDEBUG -Wl,--warn-common -Wl,--sort-common -Wl,--start-group -Wl,--end-group", I guess it is also the compile flag for file editor/vi.c.
