修复 OpenWrt 中文支持

[yangyang]

一般情况下 OpenWrt 上用 ls 等命令，中文是乱码的，这是因为默认的 busybox 不支持中文。我自己重新编译了一个支持中文的 trunk 版本 busybox，安装后中文支持就正常了。

软件包我会不定期更新，最少会做到一月一次。

如此便是甚好啊

要大了不少吧openwrt上大家最在意的就是包大小了

@20150517 就是，现在没几个路由器是用16M以上的内存做ROM的，都是4M

opkg默认下载的文件放到哪个目录了？
安装了几个文件，提示可用存储空间不足,然后空间从400k可用减少到了50k，但是程序也没安装成功。。

怎么删除？

opkg install busybox --force-reinstall

不会「大不少」，只是调整了几个参数而已。

要删除安装的软件，用「opkg remove ******」

@yangyang openwrt那格式删软件空间也不会回来

[jacy]

@582033
/usr/lib 里把没安装成功的lib删掉

[yangyang]

@20150517 你哪来的这种错误印象？


注意到删掉 wget 后 rootfs 减小了 1% 没？

@yangyang
取决于你是不是SquashFS
SquashFS is a read only compressed filesystem. While gzip is available, at OpenWrt it uses LZMA for the compression. Since SquashFS is a read only filesystem, it doesn't need to align the data, allowing it to pack the files tighter thus taking up significantly less space than JFFS2 (20-30% savings over a JFFS2 filesystem)!

+ taking up as little space as possible
+ allowing the implementation of an idiot proof FailSafe for recovery, since it is not possible to write to it
- read only
- waste space, since each time a file contained on it is modified, actually a copy of it is being copied to the second (JFFS2) partition

你的可能不是squashfs,输条mount来看看?

[yangyang]

@20150517 你又错了，Trunk 里只有 SquashFS ，而我下载的就是这个。

[20150517]

@yangyang 大哥,讨论问题不需要这么傲娇好吗?你的overlay是jffs2格式,所以你能free space,不是因为你是Squashfs
装在squashfs上的包是没法free的

OpenWRT uses squashfs. Read about squashfs at http://en.wikipedia.org/wiki/SquashFS

In short you cannot remove preinstalled packages such that flash space it released. But preinstalled packages have the advantage of being compressed in flash and therefor take a lot less flash space. Packages installed using opkg are not compressed on your router so they are less efficient in regards to the amount of flash space they occupy but they can be removed.

To do what you want you need to build your own version of openwrt using make menuconfig to select the packages you want preinstalled.

lz ，请教，这种情况怎么办
