--- Comment #14 from Davide Cavalca <davide at geexbox.org>  2009-11-30 13:51:30 UTC ---
After unpacking the tarball, our unpack script does
cat <<EOF >$BUSYBOX/Makefile.custom
HOSTCC = $HOST_CC
CROSS_COMPILE = $TARGET_PREFIX
CFLAGS += -std=gnu99 
EOF

where TARGET_PREFIX is our toolchain prefix and HOST_CC points to the system
(not crosscompiler) gcc. The actual script to build busybox simply does
ARCH=$TARGET_ARCH make $1
from busybox sources directory. On my system TARGET_ARCH=i386 (I compile for an
x86 target on an x86_64 build machine). The build script runs in a special
environment where, among others, the following variables are set:
CC=/home/davide/geexbox/build.i386.eglibc/toolchain/bin/i586-geexbox-linux-gnu-gcc
CFLAGS='-Os -Wall -pipe -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
-mtune=generic -march=i586 -s -fomit-frame-pointer'
CXX=/home/davide/geexbox/build.i386.eglibc/toolchain/bin/i586-geexbox-linux-gnu-g++
CXXFLAGS='-Os -Wall -pipe -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
-mtune=generic -march=i586 -s -fomit-frame-pointer'
LDFLAGS=' -s'
HOST_CC=/home/davide/geexbox/build.i386.eglibc/toolchain/bin/host-gcc
HOST_CFLAGS='-O2 -Wall -pipe'
HOST_CPPFLAGS=
HOST_CXX=/home/davide/geexbox/build.i386.eglibc/toolchain/bin/host-g++
HOST_LD=ld
HOST_LDFLAGS=
