The Linaro Toolchain and Platform Working Groups are pleased to announce the 2014.04 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 Engineering Build.
- Cross compiling ARM applications from your laptop
- Remote debugging
- Build the Linux kernel for your board
- Linaro GCC 4.8 2014.05
- Linaro Newlib 2.1 2014.02
- Linaro Binutils 2.24.0 2014.05
- Linaro GDB 7.7 2014.05
- 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:
- gcc has been updated to 4.9-2014.05, featuring performance improvements and bug fixes.
- binutils has been updated to 2.24.0-2014.05, featuring aarch64 improvements.
As announced at Linaro Connect USA 2013 Linaro GCC is moving to a pattern of quarterly stable releases, with engineering releases in the intervening months. This is a stable release. The next stable release will be the 2014.07 release. Next month’s release – 2014.06 – will be an engineering build. (This affects both the source release and binary builds).
This is the first binary release based on gcc 4.9.
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.
- There are no known issues at this point.
- 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-4.8-2013.11_linux/arm-linux-gnueabihf/libc/) or download from launchpad
If you do not want to use Linaro sysroot, you’d add option to gcc to find your sysroot:
- 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-4.8-2014.03_linux/arm-linux-gnueabihf/libc/* AARCH64-SYSTEM:/ scp -r gcc-linaro-arm-linux-gnueabihf-4.8-2014.03_runtime/* AARCH64-SYSTEM:/
