|

| 38 | As with many other programming languages, rustc (the rust compiler)
|
---|
| 39 | needs a binary from which to bootstrap. It will download a stage0 binary,
|
---|
| 40 | and several cargo files (these are actually .tar.gz source archives) at
|
---|
| 41 | the start of the build, so you cannot compile it without an internet
|

| 42 | connection.

| 57 | <para>
|
---|
| 58 | Repeated builds of this package on the same machine show a wide range
|
---|
| 59 | of build times. Some of this might be due to variations in downloading
|
---|
| 60 | the required cargo files if they are not already present, but this does
|
---|
| 61 | not seem to adequately explain the variations. Also, both the builder
|
---|
| 62 | and the user running the install will need to download the cargo crates
|
---|
| 63 | if they are not already present in <filename>~/.cargo</filename>.
|
---|
| 64 | </para>
|
---|
| 65 | <para>
|
---|
| 66 | If you use a DESTDIR method to install, you will only need to download
|
---|
| 67 | the crates once, for the build, saving about one-third of the build and
|
---|
| 68 | install time (but using extra space for the install). Similarly if you
|
---|
| 69 | were to build as root, or if your user is allowed to run <command>sudo
|
---|
| 70 | ./x.py install</command> - but those methods are dangerous.

| 136 | This package is updated on a six-weekly release cycle. Because it is

| 137 | such a large and slow package to build, and is at the moment only used
|
---|
[948f91a1] | 138 | by two packages in this book, the BLFS editors take the view that it

[4c6edac] | 139 | should only be updated when that is necessary.

[9dc2505] | 176 | as with the build, that will use all available CPUs. This runs many suites

[4c6edac] | 177 | of tests (in an apparently random order), three may fail:

| 178 | compile-fail/issue-37131.rs and run-make/target-without-atomics both try to

[326f830] | 181 | <application>gdb</application> has not been installed. Several other tests in

[67687b75] | 182 | run-make can also fail. With <application>glibc-2.27</application> the stack

| 183 | guard page has been moved to just beyond the stack, instead of within it. That

|
---|
