Hence you need a cross linker. + +**Install it** - here follow whatever guide you have for the target arch. Distributions may also ship with cross toolchains. Example for Ubuntu 18.04: + +`sudo apt install gcc-8-multilib-arm-linux-gnueabihf` + +**Tell rustc where to find it** - in [.cargo/config](https://doc.rust-lang.org/cargo/reference/config.html) add the following: + +``` +[target.armv7-unknown-linux-gnueabihf] +linker = "arm-linux-gnueabihf-gcc-8" +``` + +Target rust std +--------------- + +This one's easy, just run rustup: + +`rustup target add armv7-unknown-linux-gnueabihf` + + +Target dbus libraries +--------------------- + +**Installing the libraries** + +Now to the more challenging part. Since we link to a C library `libdbus-1.so`, we also need the target version of that library. However, `libdbus-1.so` in itself links to a systemd library (at least it does so here) which in turn links to other libraries etc, so we need target versions of those libraries too. + +Getting an entire rootfs/image is probably the easiest option. The rootfs needs to have `libdbus-1-dev` installed. I e: + + * Boot your target (i e, a raspberry), install `libdbus-1-dev` on it, turn it off and put the SD card into your computer's SD card reader. Mount the partition. + * If the above is not an option, you could download an image, mount it at the right offset, like this (ugly hack!) `sudo mount -o loop,offset=50331648 2019-04-08-raspbian-stretch-lite.img /tmp/mnt` and then, to manually make the symlink that `libdbus-1-dev` does for you: `cd /tmp/mnt/usr/lib/arm-linux-gnueabihf && ln -s ../../../lib/arm-linux-gnueabihf/libdbus-1.so.3 libdbus-1.so`. + * Or you can use the alternative guide's approach to download, extract and post-process the relevant `.deb` files manually. This might be a preferrable option if an entire image/rootfs would be too large. + +**Finding the libraries** + +When not cross compiling, finding the right library is done by a `build.rs` script which calls `pkg-config`. This will not work when cross compiling because it will point to the `libdbus-1.so` on the host, not the `libdbus-1.so` of the target. +Maybe it is possible to teach `pkg-config` how to return the target library instead, but I have not tried this approach. Instead we can override build script altogether and provide the same info manually. This is possible because `libdbus-sys` has a `links = dbus` line. + +For the example below we assume that we have mounted a Raspbian rootfs on `/tmp/mnt`, and that the cross linker came with some basic libraries (libc, libpthread etc) that are installed on `/usr/arm-linux-gnueabihf/lib`. Unfortunately, we can't use the basic libraries that are present on the image, because they might contain absolute paths. + +And so we add the following to [.cargo/config](https://doc.rust-lang.org/cargo/reference/config.html): + +``` +[target.armv7-unknown-linux-gnueabihf.dbus] +rustc-link-search = ["/usr/arm-linux-gnueabihf/lib", "/tmp/mnt/usr/lib/arm-linux-gnueabihf"] +rustc-link-lib = ["dbus-1"] +``` + + +Finally +------- + +If we are all set up, you should be able to successfully compile with: + +`cargo build --target=armv7-unknown-linux-gnueabihf` diff --git a/third_party/rust/libdbus-sys/src/lib.rs b/third_party/rust/libdbus-sys/src/lib.rs new file mode 100644 index 0000000000..c93388c108 --- /dev/null +++ b/third_party/rust/libdbus-sys/src/lib.rs @@ -0,0 +1,315 @@ +use std::os::raw::{c_void, c_char, c_uint, c_int, c_long};
