docker based build based on the rack v2 sources on armv7l and aarch64 on debian bookworm

vcvrack-dockerbuild-v2

docker based build for vcvrack v2 on debian bullseye for aarch64, armv7l, x86_64 and i686

still very much work in progress ... it might work on raspberry pi os as well, but most probably only on the 64bit version of it as it is essentially a debian bullseye system

very short summary of how to use this:

• you need a system of the arch you want to build for (for example aarch64 for aarch64)
• docker needs to be installed and running well on that system
• clone this repo somewhere and make sure there are around 50+ gb of space available
• first build the docker image used for the build process: ./docker-buildenv.sh
• prepare for the rack build: ./prepare.sh
• prepare for the module build: ./prepare-modules.sh
• enter the docker buildenv: ./buildenv.sh
• inside of that start the rack build: /compile/build.sh
• inside of that start the module build: /compile/build-modules.sh
• exit the docker buildenv: exit
• build a distribution dir: ./make-dist.sh
• the result will be a dir dist - put this somewhere and run "./Rack -d" in it to start rack

rack-dockerbuild-v2's Issues

some questions regarding building on rpi5

Hello,

I tried builing your rack-dockerbuild-v2 on a Raspbberry pi 5 (with 1TB nvme m.2 storage).

for some reason, the build stops in the /compile/build-modules.sh and doesn't exit to shell.

this is the last output:

=== Volume1 ===

if i break (ctrl-c) it,

also, I don't know much about it, but seems your tune options are for RPI3 ?

grep mtune *

should these be changed for RPI5 ? (cortex-a78)
I also have RPI 4 (cortex-a76) - offcause I'd appreciate optimized builds for both machines.

Problem when creating modules

Never mind, user error... I thought 20gb would be enough for the build but its nowhere near.

Failed to build the environment with docker-buildenv-raspbian.sh

Hi,

I tried to build this on my RPi 4 but I ran into problems when trying to create the build environments for raspbian.

    E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
    E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

I tried running with sudo so debootstrap is called but I got the following error:

    sha256:574765e85e1a8fc6fe4cd1af60bcb377b0667ba75b29321e51931857f4617a85

Do you know how can I fix this? I looks like building with the ubuntu image works.
