I'd like for Linux Guix builds to be working again, and we can rebase #18818.

Hint: To blow everything away, you may want to use:
|
|
|
|
$ git clean -xdff --exclude='/depends/SDKs/*'
|
|
|
|
Specifically, this will remove all files without an entry in the index,
|
|
excluding the SDK directory. Practically speaking, this means that all ignored
|
|
and untracked files and directories will be wiped, allowing you to start anew.

|
# Explanation of `guix environment` flags:
|
|
#
|
|
# --container run command within an isolated container
|
|
#
|
|
# Running in an isolated container minimizes build-time differences
|
|
# between machines and improves reproducibility
|
|
#
|
|
# --pure unset existing environment variables
|
|
#
|
|
# Same rationale as --container
|
|
#
|
|
# --no-cwd do not share current working directory with an
|
|
# isolated container
|
|
#
|
|
# When --container is specified, the default behavior is to share
|
|
# the current working directory with the isolated container at the
|
|
# same exact path (e.g. mapping '/home/satoshi/bitcoin/' to
|
|
# '/home/satoshi/bitcoin/'). This means that the $PWD inside the
|
|
# container becomes a source of irreproducibility. --no-cwd disables
|
|
# this behaviour.
|
|
#
|
|
# --share=SPEC for containers, share writable host file system
|
|
# according to SPEC
|
|
#
|
|
# --share="$PWD"=/bitcoin
|
|
#
|
|
# maps our current working directory to /bitcoin
|
|
# inside the isolated container, which we later cd
|
|
# into.
|
|
#
|
|
# While we don't want to map our current working directory to the
|
|
# same exact path (as this introduces irreproducibility), we do want
|
|
# it to be at a _fixed_ path _somewhere_ inside the isolated
|
|
# container so that we have something to build. '/bitcoin' was
|
|
# chosen arbitrarily.

# The isolated container has no network access as it's in a

|
# different network namespace from the main machine, so we have to
|
|
# make the downloaded depends sources available to it. The sources
|
|
# should have been downloaded prior to this invocation.
