Fedora/ARM cross toolchain

We provide ARM toolchain packages for i386 and x86_64 that are built from the same sources as the Fedora native toolchain packages (binutils, gcc, gdb, glibc.)

To install this toolchain on your Fedora machine, do:

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.

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.
