Fedora/ARM 交叉编译工具链
The F12 ARM initiative created ARM cross toolchain packages for i386 and x86_64 that are built from the same sources as the Fedora native toolchain packages (binutils, gcc, gdb, glibc.) Right now these are gcc-4.1 vintage.
安装这个工具链到你的Fedora计算机:
# cd /etc/yum.repos.d/ # wget http://ftp.linux.org.uk/pub/linux/arm/fedora/cross/cross.repo # yum install armv5tel-redhat-linux-gnueabi-gcc
This will install everything necessary to run the C compiler and cross-build ARM libraries and binaries that are entirely binary compatible with the native Fedora/ARM libraries and binaries.
如果你对此感兴趣，可以从这里获得源码包.
Cross-compiling ARM userland binaries
使用交叉编译器编译一个ARM下的Hello World程序的范例： To cross-compile the canonical Hello World example for ARM, do:
$ armv5tel-redhat-linux-gnueabi-gcc -Wall -o hello hello.c $
Cross-compiling ARM kernels
你也可以使用交叉编译工具链来交叉编译一个ARM架构下的Linux内核，只需要修改在顶层目录下的Makefile文件的以下两行： You can also use the cross-toolchain to cross-build an ARM Linux kernel, by changing these two lines in the top-level Makefile:
ARCH ?= $(SUBARCH) CROSS_COMPILE ?=
为:
ARCH ?= arm CROSS_COMPILE ?= armv5tel-redhat-linux-gnueabi-
然后像往常一样编译你的内核。 and then building your kernel as usual.
