./compile.sh

Docker Build

Build without installing a bunch of dev packages, also for a different distro by changing build-arg.

# pull source from debian sid
./pullsrc.sh

# build a docker image that fits your target system.
docker build \
    -t opensshbuild \
    --build-arg DISTRO=ubuntu \
    --build-arg DISTVER=22.04 \
    --build-arg APT_MIRROR=ftp.us.debian.org \
    -f ./docker/Dockerfile \
    .

# run the build process
docker run --rm -v $PWD:/data/output opensshbuild

# clean up docker image
docker image rm opensshbuild
docker builder prune

Install DEBs

All DEBs are generated right under build directory. (either direct build or docker build).

ls -l build/*.deb

# Ignore thoses files with dbgsym and tests
find build -maxdepth 1 ! -name '*dbgsym*' ! -name '*tests*' -name '*.deb' | xargs sudo apt install -y
