Hello all,
I was trying to find a way to compile rustc-1.25.0 on an offline
machine. It finally appeared to be possible, and I'd like BLFS to
present this way of compilation (maybe as optional preparation
steps before the current ones).
The changes are as follows.
1. In addition to the rustc-1.25.0-src.tar.gz, we need these tarballs:
https://static.rust-lang.org/dist/2018-02-15/rust-std-1.24.0-i686-unknown-linux-gnu.tar.gz
https://static.rust-lang.org/dist/2018-02-15/rustc-1.24.0-i686-unknown-linux-gnu.tar.gz
https://static.rust-lang.org/dist/2018-02-15/cargo-0.25.0-i686-unknown-linux-gnu.tar.gz
2. Cargo package registry must be fetched into appropriate location.
This can be done with the following commands (requires git):
### BEGIN
mkdir -pv "$HOME/.cargo/registry/index/github.com-1ecc6299db9ec823"
pushd "$HOME/.cargo/registry/index/github.com-1ecc6299db9ec823"
git init .
git fetch --tags https://github.com/rust-lang/crates.io-index
refs/heads/master:refs/remotes/origin/master
touch .cargo-index-lock
popd
### END
3. We need to download the dependencies – Rust packages AKA crates,
and place them into appropriate location. This can be done using the
following bash commands:
### BEGIN
mkdir -pv "$HOME/.cargo/registry/cache/github.com-1ecc6299db9ec823/"
pushd "$HOME/.cargo/registry/cache/github.com-1ecc6299db9ec823/"

4. After all these downloads have been done, we can finally do the
(BLFS implied) extraction of rustc-1.25.0-src.tar.gz, cd into the
resulting directory, and from there:
### BEGIN
mkdir -pv build/cache/2018-02-15
ln -sv "$PWD"/../rust-std-1.24.0-i686-unknown-linux-gnu.tar.gz
build/cache/2018-02-15/
ln -sv "$PWD"/../rustc-1.24.0-i686-unknown-linux-gnu.tar.gz
build/cache/2018-02-15/
ln -sv "$PWD"/../cargo-0.25.0-i686-unknown-linux-gnu.tar.gz
build/cache/2018-02-15/
### END
5. After all these steps you no longer need Internet connection, so
you can simply continue as you would following current BLFS
instructions. I've actually built rustc on an offline machine using
these preparations before going offline, and it worked nicely.
Note about DESTDIR: it seems you don't actually have to use this way:
you can simply set HOME environment variable to the normal user's home
directory. Then Cargo should look for its registry and cache in the
same place as while building, so it won't try to download all these
files while installing.
While I appreciate your efforts, I'm afraid that what you propose has
too much maintenance effort for the benefit it gives. rust is really a
PITA.
