Check that your project is able to build with conventional cross or cargo commands against a single target. A project that does not compile against a single target, will naturally have difficulty when attempting to cross-compile for multiple targets.
Note that Rust introduces new, under-supported targets all the time. We try to keep up, but sometimes we miss a few of these. Regardless, you can declare which targets are disabled, by writing a custom pattern for the -e / --exclude-targets flag.
Some targets may lack stock support for the Rust std library. This is common for bare metal or embedded targets. For these kinds of targets, you have several strategies for resolution:
std implementation. Reach out to specialists for the specific target involved.std library, in both your code, as well as the dependency tree. This is actually common practice for many Rust projects, as an proactive stance on embedded development support.crit hides a lot of compiler noise. While a target is building, you can use common Docker commands to inspect the compilation process:
docker ps -adocker logs [--follow] <container id>Yes, it sure is! Almost as slow as using Virtual Machines for cross-compilation.
Rustaceans come to expect that the Rust compiler is analytical, spending more time optimizing programs, so that the final binaries will run safer and faster. The Rust compiler often taking a long time to compile each individual target.
Naturally, when cross-compiling multiple targets, that time multiplies by the number of targets.
