Update (2007-04-20): added Mac OS X Intel version

This package is intended for and was tested with small ARM microcontrollers like LPC21xx, AT91SAM7, ST7, ADuC7000, but should work for any system supported by arm-elf. Take a look at the configuration of the components below to find out whether it suits your application.

[edit] Content (Build 2)

This build is similar to Martin Thomas' WinARM package. The main difference to GNUARM is that in WinARM and this build Newlib is compiled with the option -DREENTRANT_SYSCALLS_PROVIDED, as recommended in Bill Gatliff's article "Porting and Using Newlib in Embedded Systems".

• Binutils 2.16.1 configured with --target=arm-elf --enable-interwork --enable-multilib
• GCC 4.1.0 with patched t-arm-elf, configured with --target=arm-elf --enable-interwork --enable-multilib --enable-languages="c,c++" --with-newlib
• Newlib 1.14.0 configured with --target=arm-elf --enable-interwork --enable-multilib and -DREENTRANT_SYSCALLS_PROVIDED
• GDB 6.4 configured with --target=arm-elf --enable-interwork --enable-multilib

Everything is built with --prefix=/usr/local/arm. The Linux version is compiled with Debian Sarge, the Mac OS X PPC version with 10.3 (Panther), the Mac OS Intel Version with 10.4 (Tiger). All binaries are stripped. The build process on Linux and Mac OS X is identical.
