| 39 | This package is updated on a six-weekly release cycle. Because it is
|
|---|
| 40 | such a large and slow package to build, is at the moment only required
|
|---|
| 41 | by a few packages in this book, and particularly because newer versions
|
|---|
| 42 | tend to break older mozilla packages, the BLFS editors take the view that
|
|---|
| 43 | it should only be updated when that is necessary (either to fix problems,
|
|---|
| 44 | or to allow a new version of a package to build).
|
|---|
| 45 | </para>
|

|
|---|
| 47 | <para>
|
|---|
| 48 | As with many other programming languages, rustc (the rust compiler)
|
|---|
| 49 | needs a binary from which to bootstrap. It will download a stage0 binary
|
|---|
| 50 | and many cargo crates (these are actually .tar.gz source archives) at
|
|---|
| 51 | the start of the build, so you cannot compile it without an internet
|
|---|
| 52 | connection.
|
|---|
| 53 | </para>
|
|---|
| 54 |
|
|---|
| 55 | <para>
|
|---|
| 56 | These crates will then remain in various forms (cache, directories of
|
|---|
| 57 | extracted source), in <filename class="directory">~/.cargo</filename> for
|
|---|
| 58 | ever more. It is common for large <application>rust</application> packages
|
|---|
| 59 | to use multiple versions of some crates. If you purge the files before
|
|---|
| 60 | updating this package, very few crates will need to be updated by the
|
|---|
| 61 | packages in this book which use it (and they will be downloaded as
|
|---|
| 62 | required). But if you retain an older version as a fallback option and
|
|---|
| 63 | then use it (when <emphasis>not</emphasis> building in
|
|---|
| 64 | <filename class="directory">/usr</filename>), it is likely that it will
|
|---|
| 65 | then have to re-download some crates. For a full download (i.e. starting
|
|---|
| 66 | with an empty or missing <filename class="directory">~/.cargo</filename>)
|
|---|
| 67 | downloading the external cargo files for this version only takes a minute
|
|---|
| 68 | or so on a fast network.

|
|---|
| 71 | <note>
|
|---|
| 72 | <para>
|
|---|
| 73 | Although BLFS usually installs in <filename
|
|---|
| 74 | class="directory">/usr</filename>, when you later upgrade to a newer
|
|---|
| 75 | version of <application>rust</application> the old libraries in <filename
|
|---|
| 76 | class="directory">/usr/lib/rustlib</filename> will remain, with various
|
|---|
| 77 | hashes in their names, but will not be usable and will waste space. The
|
|---|
| 78 | editors recommend placing the files in the <filename
|
|---|
| 79 | class="directory">/opt</filename> directory. In particular, if you
|
|---|
| 80 | have reason to rebuild with a modified configuration (e.g. using the
|
|---|
| 81 | shipped LLVM after building with shared LLVM, perhaps to compile crates
|
|---|
| 82 | for architectures which the BLFS LLVM build does not support)
|
|---|
| 83 | it is possible for the install to leave a broken
|
|---|
| 84 | <command>cargo</command> program. In such a situation, either remove
|
|---|
| 85 | the existing installation first, or use a different prefix such as
|
|---|
| 86 | /opt/rustc-&rust-version;-build2.
|
|---|
| 87 | </para>
|
|---|
| 88 |
|
|---|
| 89 | <para>
|
|---|
| 90 | If you prefer, you can of course change the prefix to <filename
|
|---|
| 91 | class="directory">/usr</filename> and omit the
|
|---|
| 92 | <command>ldconfig</command> and the actions to add rustc to the PATH.

| 97 | The current <application>rustbuild</application> build-system will use
|
|---|
| 98 | all processors, although it does not scale well and often falls
|
|---|
| 99 | back to just using one core while waiting for a library to compile.
|
|---|
| 100 | However it can be mostly limited to a specified number of processors by
|
|---|
| 101 | a combination of adding the switch <literal>--jobs <N></literal>
|
|---|
| 102 | (e.g. '--jobs 4' to limit to 4 processors) on each invocation of
|
|---|
| 103 | <command>python3 ./x.py</command> <emphasis>and</emphasis> using an
|
|---|
| 104 | environment variable <envar>CARGO_BUILD_JOBS=<N></envar>. At the

| 109 | The current version of rust's num_cpus crate now recognizes that cgroups

| 130 | Rustc defaults to building for ALL supported architectures, using a

| 142 | Unusually, a DESTDIR-style method is being used to install this package.
|

| 143 | This is because running the install as root not only downloads all of the

| 144 | cargo files again (to <filename>/root/.cargo</filename>), it then spends
|
|---|
| 145 | a very long time recompiling. Using this method saves a lot of time, at

| 146 | the cost of extra disk space.
