PPC440 is a 32-bit PowerPC processor from IBM. It supports standard PowerPC floating-point instructions through an external floating-point unit (FPU) connected on the Auxiliary Processor Unit (APU) interface. PowerPC processors on Linux are well supported by the GNU tool-chain and Crosstool-NG. We propose to build a cross tool-chain for the powerpc-440fp-linux-gnu target (i.e. a PPC440 host machine with FPU support running Linux), with the help of Crosstool-NG 1.20.0. With that cross tool-chain, you can for example build applications for Linux, a BusyBox environment and a Linux kernel for PPC440. We provides you a tarball with all the necessary material inside: Crosstool-NG 1.20.0, GNU tool-chain sources, configuration files, scripts,…

1. What you get after the build ?

You get a GNU cross tool-chain for Linux/PPC440FP:

• GNU GCC 4.8.2 C/C++ compiler (gcc, g++,…)
• GNU binutils 2.22 (objdump, readelf,…)
• GNU Standard C Library (glibc) 2.19.0
• GNU debugger 7.6.1 (gdb)

We followed these instructions with the following Crosstool-NG 1.20.0 configuration at step 5 (only changes are shown):

2. Requirements

• A Linux host machine (may work on other Un*x machines)
• The following tools: grep, sed, bash, cut, install, make, gcc, awk, bison, flex, makeinfo, automake, libtool, stat, curl, cvs, patch, tar, gzip, bzip2, lzma, readlink, binutils, ncurses, expat
• make 3.82 (may not work with make 3.81)

3. Get the material

Download that tarball. It contains all the necessary material (scripts and source codes) to get a working GNU cross tool-chain for PPC440FP.

4. Uncompress the tarball

5. Build the cross tool-chain

Run the building script:

Be patient...the process of building the cross tool-chain is very long. Once finished, the cross tool-chain is in powerpc-440fp-linux-gnu sub-directory.
