build_or32_elf_tools.sh

eCos操作系统源码

#!/bin/bash -x

# Checkout and build gnu toolchain for OpenRISC (or32 target)

# Usage:
# build_or32_elf_tools.sh [-c]
#   -c  Controls whether CVS checkout is done prior to build
#       You probably only want to use this command-line option the first time you build.

# Directory in which to checkout sources and build
BUILD_DIR=$HOME/or32-elf-src

# Target architecture/OS
TARGET=or32-elf

# Directory in which to put compiled files, exported headers, etc.
INSTALL_PREFIX=$HOME/tools/i386-redhat-linux
