 ## Introduction
 
-This openembedded layer provides the rust compiler, tools for building packages
+This OpenEmbedded layer provides the rust compiler, tools for building packages
 (cargo), and a few example projects.
 
 ## What works:
 
- - MACHINE="beaglebone" (TARGET_SYS=arm-poky-linux-gnueabi)
+ - Building `rust-native` and `cargo-native`
- - Building rust-native, rust-cross, rust-hello-world, cargo-native
+ - Building Rust based projects with Cargo for the TARGET
- - Running/using all of these (including rust-hello-world)
+   - e.g. `rustfmt` which is used by the CI system
+ - `-buildsdk` and `-crosssdk` packages
 
 ## What doesn't:
 
- - Probably some of the untested things
+ - Using anything but x86_64 as the build environment
+ - rust (built for target) [issue #81](https://github.com/meta-rust/meta-rust/issues/81)
 
 ## What's untested:
 
- - rust (built for target)
+ - cargo (built for target)
- - Other TARGETs
 
-## Common issues when packaging things using cargo
+## Building a rust package
 
- You may run into errors similar to:
+When building a rust package in bitbake, it's usually easiest to build with
+cargo using cargo.bbclass.  If the package already has a Cargo.toml file (most
+rust packages do), then it's especially easy.  Otherwise you should probably
+get the code building in cargo first.
 
-```
+Once your package builds in cargo, you can use
-| src/lib.rs:12:1: 12:35 error: can't find crate for `ffi`
+[cargo-bitbake](https://github.com/meta-rust/cargo-bitbake) to generate a bitbake
-| src/lib.rs:12 extern crate "openssl-sys" as ffi;
+recipe for it.  This allows bitbake to fetch all the necessary dependent
-|               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+crates, as well as a pegged version of the crates.io index, to ensure maximum
-```
+reproducibility.
 
- Where a "-sys" crate (or other crate) is not found. These are typically caused
+NOTE: You will have to edit the generated recipe based on the comments
-by a crate's Cargo.toml including triplet-specific dependencies and then using
+contained within it
-the crate based on a feature (most often, `#[cfg(unix)]`). Until cargo and it's
-ecosystem get their act together, you'll need to supply patches to the
-misbehaving packages. See `recipies/cargo/cargo_*.bb` for an example of how to
-do this.
 
 ## TODO
 
- - -crosssdk and -buildsdk packages
- - Upstream local rustc patches for libdir and bindir support
- - add bitbake fetch support for crates.io
- - add required cargo package registry clones in SRC_URI to prevent the need
-   for network when building.
-
 ## Pitfalls
 
- - TARGET_SYS _must_ be different from BUILD_SYS. This is due to the way configuration options are tracked for different targets.
+ - TARGET_SYS _must_ be different from BUILD_SYS. This is due to the way Rust configuration options are tracked for different targets. This is the reason we use the Yocto triples instead of the native Rust triples. See [rust-lang/cargo#3349](https://github.com/rust-lang/cargo/issues/3349).
 
 ## Dependencies
 
 On the host:
-	unknown
+ - Any `-sys` packages your project might need must have RDEPENDs for
+ the native library.
 
 On the target:
-	unknown
+ - Any `-sys` packages your project might need must have RDEPENDs for
+ the native library.
 
 ## Maintainer(s) & Patch policy
 
-Open a Pull Request
+Open a Pull Request.
+
+The master branch supports the latest master of poky. When poky creates releases, we will create a branch with the same name as the poky release. This release branch should always work with that poky release. Note that these release branches will typically be less tested than the master branch.
+
+All new patches against rust, rust-llvm, and cargo must have referenced
+upstream issues or PRs opened or an explanation why the patch cannot be
+upstreamed. This corresponds to the OpenEmbedded policy for other meta layers.
+
+More info can be seen on the wiki.

+EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
+
+#
+# Additional image features
+#
+# The following is a list of additional classes to use when building images which
+# enable extra features. Some available options which can be included in this variable
+# are:
+#   - 'buildstats' collect build statistics
+#   - 'image-mklibs' to reduce shared library files size for an image
+#   - 'image-prelink' in order to prelink the filesystem image
+#   - 'image-swab' to perform host system intrusion detection
+# NOTE: if listing mklibs & prelink both, then make sure mklibs is before prelink
+# NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended
+# image-prelink disabled for now due to issues with IFUNC symbol relocation
+USER_CLASSES ?= "buildstats image-mklibs"
+
+#
+# Runtime testing of images
+#
+# The build system can test booting virtual machine images under qemu (an emulator)
+# after any root filesystems are created and run tests against those images. To
+# enable this uncomment this line. See classes/testimage(-auto).bbclass for
+# further details.
+#TEST_IMAGE = "1"
+#
+# Interactive shell configuration
+#
+# Under certain circumstances the system may need input from you and to do this it
+# can launch an interactive shell. It needs to do this since the build is
+# multithreaded and needs to be able to handle the case where more than one parallel
+# process may require the user's attention. The default is iterate over the available
+# terminal types to find one that works.
+#
+# Examples of the occasions this may happen are when resolving patches which cannot
+# be applied, to use the devshell or the kernel menuconfig
+#
+# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
+# Note: currently, Konsole support only works for KDE 3.x due to the way
+# newer Konsole versions behave
+#OE_TERMINAL = "auto"
+# By default disable interactive patch resolution (tasks will just fail instead):
+PATCHRESOLVE = "noop"
+
+#
+# Disk Space Monitoring during the build
+#
+# Monitor the disk space during the build. If there is less that 1GB of space or less
+# than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
+# shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
+# of the build. The reason for this is that running completely out of space can corrupt
+# files and damages the build in ways which may not be easily recoverable.
+# It's necesary to monitor /tmp, if there is no space left the build will fail
+# with very exotic errors.

+# Shared-state files from other locations
+#
+# As mentioned above, shared state files are prebuilt cache data objects which can
+# used to accelerate build time. This variable can be used to configure the system
+# to search other mirror locations for these objects before it builds the data itself.
+#
+# This can be a filesystem directory, or a remote url such as http or ftp. These
+# would contain the sstate-cache results from previous builds (possibly from other
+# machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
+# cache locations to check for the shared objects.
+# NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH

+When using a native llvm-config from inside a sysroot, we need llvm-config to

+llvm-config from a target sysroot.
