Cross Compiler build process preparation to download the source package: you can download the source package binutils-2.17.tar.gz ftp://ftp.gnu.org gcc-3.4.6.tar.gz glibc-2.3.6.tar.gz or to ftp://sourceware.org/pub/download. Put the source code package in the/home/zht/cross-compiler/build-tools/directory. You can. Put the patch file in the/home/zht/cross-compiler/build-tools/patch directory. Prepare the kernel source code package: linux-2.4.27.tar.gz patch-2.4.27-vrs1 2.4.27vrs1-at91-17032005.patch prepare the source code for the target kernel in the/home/zht/cross-compiler/kernel directory and configure the compilation. 1 prepare the kernel header file # cd/home/zht/cross-compiler/# mkdir-P/usr/loca/ARM-Linux/include # cp-r kernel/linux-2.4.27/include /Linux // usr/local/ARM-Linux/include/# cp-r kernel/linux-2.4.27/include/ASM-arm // usr/local/ARM-Linux /include/ASM # cp-r kernel/linux-2.4.27/include/ASM-generic // usr/local/ARM-Linux/include2 binutils setting # cd build-tools /# mkdir build-binutils # tar zxvf binutils-2.17.tar.gz # cd build-binutils /#.. /binutils-2.17/configure -- target = arm-Linux -- prefix =/usr/local/arm # Make # make install View: # ls/usr/local/ARM/bin/set Environment Variables
