add an autoconf command line example

Set up a cross-build machine for the Raspberry Pi

Prerequisites

This document focuses on Debian hosts. Debian derivatives such as Ubuntu should work with minor changes.

Downloads

Alternatively, these can be retrieved using Git. Unpack them in two directories called firmware and tools.

Environment variables

  • Set RASPI_SDK_ROOT to the directory containing firmware and tools.
  • Add the following directory to PATH:
$RASPI_SDK_ROOT/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin

Bitten configuration

For Lol Engine autobuilders, add the following section to the bitten machine file:

[raspi]
version = 0

Building autoconf projects

For simple autoconf projects (using ./configure ; make) the following command can now be used:

RASPI_INCLUDES="$RASPI_SDK_ROOT/firmware/opt/vc/include"
RASPI_LIBS="$RASPI_SDK_ROOT/firmware/opt/vc/lib"

./configure --host=arm-bcm2708hardfp-linux-gnueabi \
    CPPFLAGS="-I$RASPI_INCLUDES -I$RASPI_INCLUDES/interface/vcos/pthreads" \
    LDFLAGS="-L$RASPI_LIBS"

make
