Rustc-1.19.0

Installation of Rust

Note

This package is updated on a six-weekly release cycle. Because it is such a large and slow package to build, and is at the moment only used by one package in this book, the BLFS editors take the view that it should only be updated when that is necessary.

First create a suitable config.toml file which will configure the build :

cat <<EOF > config.toml
# see src/bootstrap/config.toml.example for more possible options
[llvm]
targets = "X86"

[build]
# install cargo as well as rust
extended = true

[install]
prefix = "/usr"
docdir = "share/doc/rustc-1.19.0"
channel = "stable"
EOF

Now install Rust by running the following commands:

./x.py build

To run the tests issue ./x.py test --verbose --no-fail-fast >../rustc-testlog: as with the build, that will use all available CPUs. This runs maniy suites of tests (in an apparently random order), three may fail: compile-fail/issue-37131.rs and run-make/target-without-atomics both try to compile for the thumbv6m-none-eabi target, but the BLFS build does not cater for that, and all 105 tests in debuginfo-gdb will fail if gdb has not been installed.

If you wish to look at the numbers for the results, you can find the total number of tests which were considered by running:

grep 'running .* tests' ../rustc-testlog | awk '{ sum += $2 } END { print sum }'

That should report 14029 tests. Similarly, the total tests which failed can be found by running:

grep '^test result:' ../rustc-testlog | awk  '{ sum += $6 } END { print sum }'

And similarly for the tests which passed use $4, for those which were ignored (i.e. skipped) use $8 (and $10 for 'measured', $12 for 'filtered out' but both are probably zero). The breakdown does not match the overall total.

Now, as the root user:

./x.py install
