The general process of building a cross-compiler looks like this:

The sys-root is a directory on the host that partially replicates theįile system hierarchy of the target system, containing important header filesĪnd libraries compiled for the target system.

(Technically, the vendor is also part of it, but for Linux targets irrelevant

Out of the target CPU architecture, the target OS, and the application binary

The target is the type of system you are compiling for.

The host is the system you are compiling your code on.

Usually do not run on another architecture.

Architecture is with regards to a CPU.

Termsīefore we start, it will be helpful to clarify a few terms: Not guarantee that everything is absolutely correct. Represents what worked for me and tries to summarize my learnings, but I can Raspberry Pi's ARM processor, some detail adjustments along the way might beĪ final word of caution: I am no expert on cross-compilation. If you want to cross-compile for a different target architecture than the

Want to compile C programs – just skip the Rust specific steps at the end. This means this guide applies also if you just While my goal is to be able to cross-compile Rust programs, this requiresĪ fully functional C toolchain. If you are using some other OS, you will hopefully be able to figure out the Preparation and installation of dependencies) will be specific to this system. Here,įurthermore, I am doing this on a MacBook under macOS. Not all guides establish clearly what use case they are intended for). Guides for one use-case will not necessarily work for the other use-case (and Building an application that runs on an already installed OS (such as Linux),īut on a different CPU architecture than your build host.Building a (Linux) kernel on one CPU architecture to use it on another.One main gotcha is that there are two major use cases for Slightly outdated, intended for slightly different use cases, and sometimes justĬonflicting. How all the pieces fit together as all the information on the web seems to be I recently set up a cross-compilation toolchain to compile applications on my Build and install glibc for the target system.Install glibc headers and bootstrap libraries.Building and installing a minimal gcc for static linking.Putting the Linux kernel headers into place.Verify signatures of downloaded software.
