openwrt使用apt

Posted 2023-03-31

参考技术A 1、首先，进入OpenWrt的终端，执行以下命令，安装apt-get。
2、使用apt-get更新软件包，使用apt-get安装软件。

使用Rust为OpenWRT开发应用.

最近阅读了 liigo大侠 的文章 MIPS平台OpenWrt路由器系统内的Rust应用程序开发, 受益颇深, 于是产生了 将 Rust 集成到OpenWRT软件包的冲动。经过一两天的尝试，终于初步取得成功. 下面分享下具体的过程.

第一步：安装依赖项

apt-get install gyp bzip2

第二步：修改Python软件包

首先假定您在OpenWRT的目录下,
进入到 package/feeds/packages/python/patches/
打开 110-enable-zlib.patch
用如下内容覆盖

 Modules/Setup.dist |    2 +-

  打开package/feeds/packages/python/Makefile 文件,找到 define Host/Configure 节,将里面的 --without-threads 修改成 --with-threads
  最后执行 make package/feeds/packages/python/host/install V=s.

最后 在package目录下创建一个 rust目录。并新建一个Makefile

include $(TOPDIR)/rules.mk

$(eval $(call BuildPackage,rust))

针对目标平台制作补丁，并将补丁放到 package/rust/patches 目录下

以我的路由器为例: target 为 mipsel-openwrt-linux-uclibc, 我生成的补丁为:  001-append-mipsel-linux.patch

最后执行

 make package/rust/host/install V=s 进入漫长的等待吧。

如果不出意外，一切成功后，您就可以在OpenWRT里创建Rust语言编写的软件包了。
