Use rust for OPENWRT development applications. _openwrt

Recently read the article Liigo the MIPS platform OPENWRT router system within the Rust application development, the benefit is very deep, resulting in the rust integration into the OPENWRT software package impulse. After one or two days of trying, the initial success was finally achieved. Share below the specific process.

First Step: Install dependencies

Apt-get Install Gyp bzip2

Step two: Modify the Python package

Let's assume that you're in the OpenWrt directory,
Into the package/feeds/packages/python/patches/
Open 110-enable-zlib.patch
Overwrite with the following content

Open the Package/feeds/packages/python/makefile file, find the Define Host/configure section, modify the--without-threads inside to--with-threads
Finally execute make Package/feeds/packages/python/host/install v=s.

Finally, create a rust directory under the package directory. and create a new makefile

Make patches for the target platform and put the patches in the Package/rust/patches directory

Take my router as an example: Target is MIPSEL-OPENWRT-LINUX-UCLIBC, and the patch I generated is: 001-append-mipsel-linux.patch

Final implementation

Make Package/rust/host/install v=s into a long wait.

If nothing happens, you'll be able to create a software package in the Rust language in OpenWrt.

The above code and project have been put into GitHub.
