| 28 | The <application>Rust</application> programming language is designed

| 33 | This package is updated on a six-weekly release cycle. Because it is
|
|---|
| 34 | such a large and slow package to build, is at the moment only required
|
|---|
| 35 | by a few packages in this book, and particularly because newer versions
|
|---|
| 36 | tend to break older mozilla packages, the BLFS editors take the view that
|
|---|
| 37 | it should only be updated when that is necessary (either to fix problems,
|
|---|
| 38 | or to allow a new version of a package to build).
|
|---|

|

|
|---|
| 41 | <para>
|
|---|
| 42 | As with many other programming languages, rustc (the rust compiler)
|
|---|
| 43 | needs a binary from which to bootstrap. It will download a stage0
|
|---|
| 44 | binary at the start of the build, so you cannot compile it without an
|
|---|
| 45 | Internet connection.
|
|---|
| 46 | </para>
|
|---|
| 47 |
|
|---|
| 48 | <note>
|
|---|
| 49 | <para>
|
|---|
| 50 | Although BLFS usually installs in <filename
|
|---|
| 51 | class="directory">/usr</filename>, when you later upgrade to a newer
|
|---|
| 52 | version of <application>rust</application> the old libraries in <filename
|
|---|
| 53 | class="directory">/usr/lib/rustlib</filename> will remain, with various
|
|---|
| 54 | hashes in their names, but will not be usable and will waste space. The
|
|---|
| 55 | editors recommend placing the files in the <filename
|
|---|
| 56 | class="directory">/opt</filename> directory. In particular, if you
|
|---|
| 57 | have reason to rebuild with a modified configuration (e.g. using the
|
|---|
| 58 | shipped LLVM after building with shared LLVM, perhaps to compile crates
|
|---|
| 59 | for architectures which the BLFS LLVM build does not support)
|
|---|
| 60 | it is possible for the install to leave a broken
|
|---|
| 61 | <command>cargo</command> program. In such a situation, either remove
|
|---|
| 62 | the existing installation first, or use a different prefix such as
|
|---|
| 63 | /opt/rustc-&rust-version;-build2.
|
|---|
| 64 | </para>
|
|---|
| 65 |
|
|---|
| 66 | <para>
|
|---|
| 67 | If you prefer, you can of course change the prefix to <filename
|
|---|
| 68 | class="directory">/usr</filename>.

|

| 73 | The current <application>rustbuild</application> build-system will use
|
|---|
| 74 | all processors, although it does not scale well and often falls
|
|---|
| 75 | back to just using one core while waiting for a library to compile.
|
|---|
| 76 | However it can be mostly limited to a specified number of processors by
|
|---|
| 77 | a combination of adding the switch <literal>--jobs <N></literal>
|
|---|
| 78 | (e.g. '--jobs 4' to limit to 4 processors) on each invocation of
|
|---|
| 79 | <command>python3 x.py</command> <emphasis>and</emphasis> using an
|
|---|
| 80 | environment variable <envar>CARGO_BUILD_JOBS=<N></envar>. At the
|
|---|
| 81 | moment this is not effective when some of the rustc tests are run.

|
|---|
| 83 |
|
|---|
| 84 | <para>
|
|---|
| 85 | The current version of rust's num_cpus crate now recognizes that cgroups
|
|---|
| 86 | can be used to restrict which processors it is allowed to use. So if your
|
|---|
| 87 | machine lacks DRAM (typically, less than 2GB DRAM per core) that might be
|
|---|
| 88 | an alternative to taking CPUs offline.
|
|---|
| 89 | Read <xref linkend='build-in-cgroup'/> for how to use a cgroup.

| 99 | Rustc defaults to building for ALL supported architectures, using a
|
|---|
| 100 | shipped copy of LLVM. In BLFS the build is only for the X86
|
|---|
| 101 | architecture.
|
|---|
| 102 | If you intend to develop rust crates, this build may not be good
|
|---|
| 103 | enough for your purposes.

| 105 | <para>
|

| 106 | The build times of this version when repeated on the same machine are

| 366 | As with all large test suites, some tests might fail on some machines -
|
|---|
| 367 | if the number of additional failures is low,
|
|---|
| 368 | check the log for 'failures:' and review lines above that, particularly the
|
|---|
| 369 | 'stderr:' lines. Any mention of
|

| 370 | SIGSEGV or signal 11 in a failing test is a cause for concern.

|
|---|
| 374 | If you get any <emphasis>other</emphasis> failing test which reports an
|
|---|
| 375 | issue number then you should search for that issue. For example, when
|
|---|
| 376 | rustc >= 1.41.1 was built with a version of sysllvm before 10.0 the test
|
|---|
| 377 | for issue 69225 failed <ulink
|
|---|
| 378 | url="https://github.com/rust-lang/rust/issues/69225"/> and that should be
|
|---|
| 379 | regarded as a critical failure (they released 1.41.1 because of it).
|
|---|
| 380 | Most other failures will not be critical.

| 381 | </para>
|

| 382 |
|
|---|
| 383 | <para>
|
