This script + MUST only be run on a system which is a + just-throw-it-away-if-broken system. + +Sometimes happy developers (like me) have no choice but using terribly +restricted systems where setting up tools to run even something as +trivial as configure/make/install becomes a nightmare if not impossible. +I found it to be very handy to have some independent qemu VM at hand +which lets me install whatever I need, neither with any special software +nor any annoying privileges on a host machine. Qemu runs portable and in +user mode even doesn't need any annoying permissions at all. + + +## Setup a minimal system in your qemu VM + +This setup mainly targets debian. Nevertheless it tries to stay POSIX +compatible as far as possible. So setup a minimal install of your system +of choice and then as soon you've SSH access to a (posix) shell, you're +ready for the next step. + +Still not sure which system to use? Link below provides some candidates. +HINT: Windows IMHO is a terrible choice. So stop complaining if you go +this route. + +https://en.wikipedia.org/wiki/POSIX#POSIX-oriented_operating_systems + + +## Start VM with SSH access + +Easiest way to work with your machine is via SSH. Therefore if you've +chosen to use a qemu VM, make sure you've setup and configured sshd +properly inside the VM. Then just pass args like those to qemu: + + --device e1000,netdev=n0 --netdev user,id=n0,hostfwd=tcp:127.0.0.1:2222-:22 + +Started this way, the SSHDaemon inside the VM is accessible from your +host via "localhost" at port "2222": + + ssh localhost -p2222 + + +## Finalize by build and install whole project + +Run the "./setup" script (which is a posix shell script btw) inside the +freshly setup system. This script does all the work. Like installing +required packages, configure and build the whole project and finally +installing it into the VM so it can be tried out right away from your +VMs shell. +BTW: The script is constructed so it can be copy-pasted into a terminal. +There is no need to transfer a file to the machine beforehand. + + + + + + diff --git a/contrib/build-env-setup/setup b/contrib/build-env-setup/setup new file mode 100644 index 0000000..31c5f11 --- /dev/null +++ b/contrib/build-env-setup/setup @@ -0,0 +1,32 @@ + +echo "WARN: read (AND UNDERSTAND) the README before running this script!" +sleep 3 +exit 1 + + +true \ + && GIT_TAG="master" \ + && CONFIGURE_OPTS= \ + && PKGS_TO_ADD="ca-certificates curl gcc git make libc-dev tar" \ + && PKGS_TO_DEL="curl gcc git make libc-dev" \ + && SUDO=sudo \ + && PKGINIT="$SUDO apt update" \ + && PKGADD="$SUDO apt install -y --no-install-recommends" \ + && PKGDEL="$SUDO apt purge -y" \ + && PKGCLEAN="$SUDO apt clean" \ + && WORKDIR="${HOME:?}/work" \ + && true \ + && mkdir -p "${WORKDIR:?}" && cd "${WORKDIR:?}" \ + && ${PKGINIT:?} && ${PKGADD:?} $PKGS_TO_ADD \ + && git clone --depth 42 --branch "${GIT_TAG:?}" https://github.com/hiddenalpha/bulk-ln.git . \ + && git config advice.detachedHead false \ + && git checkout "${GIT_TAG:?}" \ + && ./configure $CONFIGURE_OPTS \ + && make clean && make -j$(nproc) \ + && $SUDO make install \ + && find . -not -wholename './dist*' -delete \ + && ${PKGDEL:?} $PKGS_TO_DEL && ${PKGCLEAN:?} \ + && dirOfDistBundle="$(realpath dist)" \ + && printf '\n SUCCESS :) Distribution bundle is ready in:\n\n %s\n\n Tip: Before pulling out your hair about how to get that archive out of\n your qemu VM.
