"build_bootloader.sh" doesn't exist and "walkoff.sh up --build" fails

[ch40s]

Hey all,
I'm trying to install WALKOFF on a Debian Stretch ( armv7l/armhf) host and I noticed that build_bootloader.sh which is mentioned in the documentation doesn't exist in the repository. Did the functionality get replaced by walkoff.sh? If yes, then the documentation of Linux installation is outdated.

By the way, the command walkoff.sh up --build fails because of:

Starting WALKOFF Bootloader...
docker: Error response from daemon: attaching to network failed, make sure your network options are correct and check manager logs: context deadline exceeded.

$docker node inspect --format {{.Spec.Availability}} self
active

My package versions:

docker-compose version 1.25.0
docker-py version: 4.1.0
CPython version: 3.5.3
OpenSSL version: OpenSSL 1.1.0l
containerd.io 1.2.10

The error context deadline exceeded was caused by the kernel configuration.
If you have the same issue you can use this script to check your kernel config: https://raw.githubusercontent.com/moby/moby/master/contrib/check-config.sh

The error I'm getting now is:

The error above ffi.h: No such file or directory and a similar one goes away after doing the changes mentioned in #252 (install libffi-dev and libssl-dev via app_sdk/Dockerfile).

The new error I'm getting is the following. I assume gcc is missing and needs to be installed but not sure yet exactly where this should be implemented.

It looks like you didn't add that line to the umpire Dockerfile. I'm going to go ahead and close this issue, pull your change to app_sdk, and add that line to the umpire. Let me know if this is still an issue.
