pandora_configure.sh

#!/bin/bash
#
# This script is supposed to ease using the crosscompiler toolchain for the
# pandora with configure based build systems.
#
# Usage example:
# from inside the dir where you normally run a commandline like the following:
#    ./configure --prefix=$HOME/pandora-dev/testcase --disable-strict-compilation
# run this instead to have everything setup for cross compilation:
#    $HOME/pandora-dev/sdk_utils/pandora_configure.sh --prefix=$HOME/pandora-dev/testcase --disable-strict-compilation
# afterwards call 'make' and 'make install', as you are used to. For
# 'make install' you should define a '--prefix=' or you might get problems with
# your normal system.

# first run configure without setting up the cross compiler and make a copy of
# the src/hw_cpu directory

./configure && \
make -C src/hw_cpu && \
rm -rf src/hw_cpu-native && \
cp -r src/hw_cpu src/hw_cpu-native && \
make distclean
