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.
ELPHEL_SOURCEDIR and TOOLCHAIN values below are installation dependent, check if it match yours.
Contents
First
You must source init_env from the Elphel firmware source directory, eg:
ELPHEL_SOURCEDIR=/usr/local/src/elphel-cvs/353/elphel353 cd $ELPHEL_SOURCEDIR source init_env
Setting environment variables
(check ./configure --help and the Makefile to see if more is needed)
# toolchain TOOLCHAIN=/usr/local/cris export PATH=${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=${CFLAGS}
When the software is packaged using autoconf and automake
You normally just have to run:
./configure --host=crisv32-axis-linux-gnu --prefix=/usr/local/crisv32 [ other options ] make make install
and mount or copy the resulting /usr/local/crisv32 to the camera (you may want to strip binaries and remove documentation before)
Then to run the software on the camera you may have to define:
export PATH=/usr/local/crisv32/bin:$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
