请教：PowerPC的2.6移植

Question

为什么2.6内核找不到关于PowerPC的CPU架构的支持选项啊？是不是要找特殊的kernel那？

Answer 1

确信2.6可以移植的

Answer 2

你用的什么版本内核，PowerPC不支持的话就笑话了

Kernel Makefile

# Cross compiling and selecting different set of gcc/bin-utils
# ---------------------------------------------------------------------------
#
# When performing cross compilation for other architectures ARCH shall be set
# to the target architecture. (See arch/* for the possibilities).
# ARCH can be set during invocation of make:
# make ARCH=ia64
# Another way is to have ARCH set in the environment.
# The default ARCH is the host where make is executed.

# CROSS_COMPILE specify the prefix used for all executables used
# during compilation. Only gcc and related bin-utils executables
# are prefixed with $(CROSS_COMPILE).
# CROSS_COMPILE can be set on the command line
# make CROSS_COMPILE=ia64-linux-
# Alternatively CROSS_COMPILE can be set in the environment.
# Default value for CROSS_COMPILE is not to prefix executables
# Note: Some architectures assign CROSS_COMPILE in their arch/*/Makefile

我用2.6.11，在make menuconfig arch=ppc后，根据某2.4PPC内核选了一些选项，退出make,出错很多，而且我发现该版本内核好像不支持摩托罗拉ppc8540,只支持Freescale的8540，这样就只能从2.4下把程序移植到2.6内核了，太麻烦了～

Answer 4

cross compile的话还得指定工具链吧
如果编译器是ppc-linux-gcc话就得
make arch=ppc CROSS_COMPILE=ppc-linux-

Answer 5

手头上只有一个很不稳定的2.4内核，想搞一个2.6内核稳定版本，哪位高人有经验介绍一下啊？PPC8540，摩托罗拉的

我装的FC5，但是系统并没有ppc-linux-是找不到的，我有一款PPC的编译器设置CROSS_COMPILE或者CC为绝对路径都不行，请问怎么才能顺利的将2.6内核编译那？

Answer 7

我的开发环境是FC5 装了ELDK的85xx,这样应该就可以了吧？
