| 43 | This package is updated on a six-weekly release cycle. Because it is
|
---|
| 44 | such a large and slow package to build, and is at the moment only required
|
---|
[80720f4a] | 45 | by a few packages in this book, the BLFS editors take the view that it
|
---|
[25997c4a] | 46 | should only be updated when that is necessary (either to fix problems,
|
---|
| 47 | or to allow a new version of <application>firefox</application> to build).

[03d537cd] | 50 | <para>
|
---|
| 51 | As with many other programming languages, rustc (the rust compiler)
|
---|
[a7b1bddc] | 52 | needs a binary from which to bootstrap. It will download a stage0 binary
|
---|
| 53 | and many cargo crates (these are actually .tar.gz source archives) at
|
---|
[03d537cd] | 54 | the start of the build, so you cannot compile it without an internet
|
---|
| 55 | connection.
|
---|
| 56 | </para>
|
---|
| 57 |
|
---|
[25997c4a] | 58 | <para>
|
---|
| 59 | These crates will then remain in various forms (cache, directories of
|
---|
| 60 | extracted source), in <filename class="directory">~/.cargo</filename> for
|
---|
| 61 | ever more. It is common for large <application>rust</application> packages
|
---|
| 62 | to use multiple versions of some crates. If you purge the files before
|
---|
| 63 | updating this package, very few crates will need to be updated by the
|
---|
| 64 | packages in this book which use it (and they will be downloaded as
|
---|
| 65 | required). But if you retain an older version as a fallback option and
|
---|
[b05ea0b] | 66 | then use it (when <emphasis>not</emphasis> building in
|
---|
[25997c4a] | 67 | <filename class="directory">/usr</filename>), it is likely that it will
|
---|
[b05ea0b] | 68 | then have to re-download some crates. For a full download (i.e. starting
|
---|
[25997c4a] | 69 | with an empty or missing <filename class="directory">~/.cargo</filename>)
|
---|
| 70 | downloading the external cargo files for this version only takes a minute
|
---|
| 71 | or so on a fast network.

| 74 | <note>
|

| 75 | <para>
|
---|
[d396c65] | 76 | Although BLFS usually installs in <filename
|
---|
| 77 | class="directory">/usr</filename>, when you later upgrade to a newer
|
---|
| 78 | version of <application>rust</application> the old libraries in <filename
|
---|
| 79 | class="directory">/usr/lib/rustlib</filename> will remain, with various
|
---|
| 80 | hashes in their names, but will not be usable and will waste space. The
|
---|
| 81 | editors recommend placing the files in the <filename
|
---|
| 82 | class="directory">/opt</filename> directory. In particular, if you
|
---|
| 83 | have reason to rebuild with a modified configuration (e.g. using the
|
---|
| 84 | shipped LLVM after building with shared LLVM, but perhaps also the
|
---|
| 85 | reverse situation) it it possible for the install to leave a broken
|
---|
| 86 | <command>cargo</command> program. In such a situation, either remove
|
---|
| 87 | the existing installation first, or use a different prefix such as
|
---|
| 88 | /opt/rustc-&rust-version;-build2.

[d396c65] | 92 | If you prefer, you can of course change the prefix to <filename

| 111 | Rustc defaults to building for ALL supported architectures, using a
|
---|
[4f8ca94] | 112 | shipped copy of LLVM. In BLFS the build is only for the X86
|
---|
| 113 | architecture. Rustc still claims to require Python 2, but that is only
|
---|
| 114 | really necessary when building some other architectures with the
|
---|
| 115 | shipped LLVM.
|
---|
[d396c65] | 116 | If you intend to develop rust crates, this build may not be good

[b05ea0b] | 117 | enough for your purposes.

[bb0652ca] | 125 | Unusually, a DESTDIR-style method is being used to install this package.
|
---|
| 126 | This is because running the install as root not only downloads all of the
|
---|
[a7b1bddc] | 127 | cargo files again (to <filename>/root/.cargo</filename>), it then spends
|
---|
[7d259126] | 128 | a very long time recompiling. Using this method saves a lot of time, at

---|
| 129 | the cost of extra disk space.
