This procedure is intended to test software before taking time to include it in the firmware build,

or to build software that would be too big to fit into the firmware image.

First

ELPHEL_SOURCEDIR and TOOLCHAIN values below are installation dependent, check if it match yours.

Setting environment variables

You must source init_env from the Elphel firmware source directory, eg:

ELPHEL_SOURCEDIR=/usr/local/src/elphel-cvs/353/elphel353
cd $ELPHEL_SOURCEDIR
source init_env

and set the following variables:

# toolchain
TOOLCHAIN=/usr/local/cris
export PATH=${TOOLCHAIN}/crisv32-axis-linux-gnu/bin:$PATH 
export PATH=${TOOLCHAIN}/bin:$PATH 

# binaries
export CC=${TOOLCHAIN}/bin/crisv32-axis-linux-gnu-gcc
export CXX=${TOOLCHAIN}/bin/crisv32-axis-linux-gnu-g++
export CPP=${TOOLCHAIN}/bin/crisv32-axis-linux-gnu-cpp

# options
export CFLAGS=-I${TOOLCHAIN}/include
export CFLAGS="${CFLAGS} -I${TOOLCHAIN}/crisv32-axis-linux-gnu/sys-include"
export CXXFLAGS=${CFLAGS}
export CPPFLAGS=${CFLAGS}
export LDFLAGS=-L${TOOLCHAIN}/lib
export LDFLAGS="${LDFLAGS} -L${TOOLCHAIN}/crisv32-axis-linux-gnu/lib/"

# user includes and libraries
export LDFLAGS="${LDFLAGS} -L/usr/local/crisv32/lib"
export CFLAGS="${CFLAGS} -I/usr/local/crisv32/include"
export CXXFLAGS=${CFLAGS}

(check ./configure --help and the Makefile to see if more is needed)

When the software is packaged using autoconf and automake

You normally just have to run:

./configure --host=crisv32-axis-linux-gnu --prefix=/usr/local/crisv32  [ other options ]
make
make install

and mount or copy the resulting /usr/local/crisv32 to the camera (you may want to strip binaries and remove documentation before)

Then to run the software on the camera you may have to define:

export PATH=/usr/local/crisv32/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/crisv32/lib:$LD_LIBRARY_PATH

When the software is not packaged using autoconf and automake

Edit the Makefile
