This procedure is intended to
- test software before including it in the cvs,
- to build software that would be too big to fit into the firmware image,
- to build standalone packages you just dont want to include into the firmware image.

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
