To cross-compile Rust for MIPS32 little-endian, follow these steps:
-
Install the required tools:
-
Rust: Follow the official Rust installation guide for your system: https://www.rust-lang.org/tools/install
-
Cross Compiler: For MIPS32 little-endian, you can use the MIPS cross-compiler from the MIPS Prosimulator project: https://github.com/mips-prosimulator/mips-prodisasm
-
-
Set up the Rust toolchain for the target architecture:
Create a new toolchain file for MIPS32 little-endian:
rustup target add mips-unknown-linux-gnuabi32 -
Configure the build script:
Create a
.cargo/configfile in your home directory with the following content:[target.mips-unknown-linux-gnuabi32] linker = "mips-linux-gnu-ld" -
Write your Rust code and save it as
main.rs. For example:fn main() { println!("Hello, world!"); } -
Build the Rust binary:
rustc -C target-cpu=mips -C target-features=+cortex-m main.rs -o mainNote: The
-C target-cpu=mipsand-C target-features=+cortex-mflags are necessary to generate MIPS assembly code. -
Link the binary with the MIPS cross-compiler:
mips-linux-gnu-ld main.o -o main -Tlink.x -L/path/to/mips-prodisasm/lib -lmipsReplace
/path/to/mips-prodisasm/libwith the path to the MIPS Prodisassembler library.
Now you should have a cross-compiled MIPS32 little-endian binary named main.
