4. Linux kernel header files (This step creates the arm-specified header files for glibc)
tar -zxvf linux-2.6.17.tar.gz
cd linux-2.6.17
make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig
make include/linux/version.h
cp -dR include/linux $PREFIX/arm-linux/include/
cp -dR include/asm-generic $PREFIX/arm-linux/include/
cp -dR include/asm-arm $PREFIX/arm-linux/include/
mv $PREFIX/arm-linux/include/asm-arm $PREFIX/arm-linux/include/asm
5. glibc-2.3.6
tar -zxvf glibc-2.3.6.tar.gz
tar -zxvf glibc-linuxthreads-2.3.6.tar.gz –directory ./glibc-2.3.6
patch -p1 -d glibc-2.3.6 < patches/5090_all_divdi3-asm-fix.patch
patch -p1 -d glibc-2.3.6 < patches/6200_all_arm-glibc-2.3.6-ioperm.patch
patch -p1 -d glibc-2.3.6 < patches/6230_all_arm-glibc-2.3.6-socket-no-weak-lias.patch
patch -p1 -d glibc-2.3.6 < patches/gcc_eh.patch.cross
mkdir arm-linux
cd arm-linux
CC=arm-linux-gcc AR=arm-linux-ar RANLIB=arm-linux-ranlib LD=arm-linux-ld ../configure –target=arm-linux –prefix=$PREFIX/arm-linux –host=arm-linux –enable-add-ons=linuxthreads –enable-shared –with-headers=$PREFIX/arm-linux/include
make
make install
6. gcc-3.4.6 full version (with glibc, support C/C++)
cd gcc-3.4.6
Change ./gcc/config/arm/t-linux back to original
cd arm-linux
../configure –target=arm-linux –prefix=$PREFIX –program-prefix=arm-linux- –enable-multilib –with-headers=$PREFIX/arm-linux/include –enable-languages=c,c++
make
make install
自此，整个arm-linux的工具链也就生成了
Issue: I encounted one problem when I cross-compiled arm gcc, the log in the following
checking for arm-linux-gcc… /root/gcc-4.2.2/arm-linux/./gcc/xgcc -B/root/gcc-4.2.2/arm-linux/./gcc/ -B/arm-linux/bin/ -B/arm-linux/lib/ -isystem /arm-linux/include -isystem /arm-linux/sys-include
