ABOUT
=======

The following archives contain a "downsized" version of the
cross-toolchain and SDK that is avaiable in the full commercial muCross package.
The free cross-toolchains presented here conatain all the basics that are needed
to either compile a Linux kernel or a bootloader but also to start enhancing
the cross-toolchains with extra libraries that can be obtained from third
party open source projects.

To use a cross toolchain download one of the following archives matching
your CPU type and architecture:

mucross-1.5-i686-linux-armv4t-linux-gnueabi-toolchain.tar.bz2
mucross-1.5-i686-linux-armv5te-linux-gnueabi-toolchain.tar.bz2
mucross-1.5-i686-linux-armv7a-linux-gnueabi-toolchain.tar.bz2
mucross-1.5-i686-linux-i586-linux-toolchain.tar.bz2
mucross-1.5-i686-linux-mipsel-linux-toolchain.tar.bz2
mucross-1.5-i686-linux-ppce300c3-linux-toolchain.tar.bz2


 INSTALLATION
==============

Unpack the archive to the root-directory ("/") of your workstation:

# cd /
# tar jxvf mucross-1.5-i686-linux-armv5te-linux-gnueabi-toolchain.tar.bz2


 USE
=====

To use the cross toolchain a set of environment variables must be set in the
environment (shell environment) in which you want to work with the cross
tools, for ARM machines this happens like this:

# . /opt/mucross/arm/environment-setup

(for other machines this is similar, just replace "arm" with the
othermachine type)

After that you can use "arm-mucross-linux-gnueabi-gcc" to compile etc.

Hint: For cross compiling a Linux kernel for ARM you would set an extra two
variable like this

# export CROSS_COMPILE=arm-mucross-linux-gnueabi-
# export ARCH=arm


 FAQ
=====

Q: Cannot run GCC and other programs from the toolchain, libmpfr1 is
missing!
A: Yes, this can happen on some Linux hosts. Please install libmpfr1ldbl to
your system, e.g. on Debian or Ubuntu (up to 11.04):
	apt-get install libmpfr1ldbl
