Architectures/ARM/CrossToolchain

zh-cn = Fedora/ARM cross toolchain =

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.

To install this toolchain on your Fedora machine, do:
 * 1) cd /etc/yum.repos.d/
 * 2) wget http://ftp.linux.org.uk/pub/linux/arm/fedora/cross/cross.repo
 * 3) 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.

You can find source packages for these if you are interested here.

Cross-compiling ARM userland binaries
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
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  ?= to: ARCH           ?= arm CROSS_COMPILE  ?= armv5tel-redhat-linux-gnueabi- and then building your kernel as usual.
