Toolchain Working Group, Linaro
The Linaro Toolchain and Platform Working Groups are pleased to
announce the 2013.07 release of the Linaro Toolchain Binaries, a
pre-built version of Linaro GCC and Linaro GDB that runs on generic
Linux or Windows and targets the glibc Linaro Evaluation Build.
Uses include:
* Cross compiling ARM applications from your laptop
* Remote debugging
* Build the Linux kernel for your board
What's included:
* Linaro GCC 4.8 2013.07-1
* Linaro Newlib 2.0 2013.06
* Linaro Binutils 2.23 2013.06
* Linaro Eglibc 2.17-2013.07-2
* Linaro GDB 7.6 2013.05
* A statically linked gdbserver
* A system root
* Manuals under share/doc/
The system root contains the basic header files and libraries to link
your programs against.
Interesting changes include:
* The sysroot is based on Linaro versions of Eglibc. About details of
Linaro Eglibc, please refer
https://releases.linaro.org/13.07/components/toolchain/eglibc-linaro.
The Linux version is supported on Ubuntu 10.04.3 and 12.04, Debian
6.0.2, Fedora 16, openSUSE 12.1, Red Hat Enterprise Linux Workstation
5.7 and later, and should run on any Linux Standard Base 3.0
compatible distribution. Please see the README about running on x86_64
hosts.
The Windows version is supported on Windows XP Pro SP3, Windows Vista
Business SP2, and Windows 7 Pro SP1.
The binaries and build scripts are available from:
https://launchpad.net/linaro-toolchain-binaries/trunk/2013.07

Other ways that you can contact us or get involved are listed at
https://wiki.linaro.org/GettingInvolved.
Know issues:
* Some version information in README are incorrect.
* gdb can not backtrace into libc.
Notes:
* To use all of the features of Linaro eglibc, the sysroot in 32-bit
toolchain release is updated to Linaro eglibc, which is 2.17. If you
get runtime errors about libc version, please get the sysroot from the
release tarball
(gcc-linaro-arm-linux-gnueabihf-4.8-2013.07-1_linux/arm-linux-gnueabihf/libc/)
or download from launchpad
https://launchpad.net/linaro-toolchain-binaries/support/01/+download/linaro…
If you do not want to use Linaro sysroot, you'd add option to gcc to
find your sysroot:
--sysroot=<directory>
* To run 32-bit application built from arm-linux-gnueabihf toolchain
in aarch64 system, you'd copy sysroot and runtime from release package
to your root of aarch64 system. i,e.
scp -r gcc-linaro-arm-linux-gnueabihf-4.8-2013.07-1_linux/arm-linux-gnueabihf/libc/*
AARCH64-SYSTEM:/
scp -r gcc-linaro-arm-linux-gnueabihf-4.8-2013.07-1_runtime/* AARCH64-SYSTEM:/
