# uv/cfg - "Build" settings for package

#---------------------------------------------------------------------

[technotes]

1. By default, if this package is built, it:

      (a) doesn't delete the "rustlocal" package tree
      (b) doesn't delete previously cached build objects
      (c) downloads sources for some  Rust libraries and programs  un-
          less they're already present
      (d) builds some  Rust libraries and programs in the  "rustlocal"
          package tree

To force actual as opposed to  cached compiles,  delete  the following
cache directory tree first:

      $PRODTREE/rustlocal/rusthome/sccache/

To  force  a  full rebuild from scratch,  delete the following package
directory tree instead:

      $PRODTREE/rustlocal/

This will both (a) download updated sources and (b) rebuild from scra-
tch.

If you do this,  you'll need to rebuild the following packages in dir-
ectory name order:

      /src/*_rust/* except for "0010_rustc"
      /src/*/_rusthigh

For  a rebuild from scratch, Internet access is required.  The results
of this type of build  are unpredictable.  This type of build may very
well fail.

#---------------------------------------------------------------------

2. The following procedure:

      export RUSTOFFLINE=true
      makelac uv --force

rebuilds  the same libraries and  programs using the same sources.  It
shouldn't access the Internet.  This  mode requires  that a full build
from scratch have been done previously.

Cached  build objects may be used  unless the following  cache tree is
deleted first:

      $PRODTREE/rustlocal/rusthome/sccache/

#---------------------------------------------------------------------

3. In the default mode,  this package requires Internet access to bui-
ld.  Builds are also non-repeatable;  i.e., the results may be differ-
ent each time and builds may not work at all.

This is  one of relatively  few packages of this type that Laclin sup-
ports.

#---------------------------------------------------------------------

4. This package doesn't modify the Rust compiler directory tree at:

      $PRODTREE/rustc/
