IBM Advance Toolchain for Linux on Power 15.0-6 is now available! Learn more
This self-contained toolchain does not rely on the system toolchain and requires minimal dependencies. Nor does it override the default Linux distribution toolchain (it is installed in /opt). The latest release includes current stable versions of the following packages:
GNU Compiler Collection (gcc, g++, and gfortran), plus individually optimized gcc runtime libraries for supported POWER processors
GNU C library (glibc), individually optimized for supported POWER processors
GNU Binary Utilities (binutils)
Decimal Floating Point Library (libdfp), optimized with hardware DFP support for POWER
IBM Power Architecture Facilities Library (PAFLib)
Plus several support libraries (libhugetlbfs, Boost, zlib...)
Why should I use Advance Toolchain?
The Advance Toolchain provides toolchain functionality earlier and a group of optimized libraries. AT is highly recommended when you want to build an optimized CPU-bound application on POWER. It's also useful when you want some of the new toolchain functionalities on POWER before they make it into a distribution. Also, you must use AT when you link with a library built with AT.
In some scenarios, you do not get many advantages by using the Advance Toolchain, and it is easier to use the distribution's toolchain that usually performs well. Such cases include building applications that are not CPU-bound and on I/O constrained environments.

Did you know?
The Advance Toolchain provides cross compilers that run on Intel x86 and generate code for Power, which allows teams to start developing by compiling and linking an application targeted for the POWER architecture without requiring access to an actual POWER system. The binaries produced can then be run in a POWER runtime environment (either real or emulated).
