Joy of Think

Find a google project for building perl in android: perldroid which has a wiki page.
I follow the instruction of it and try it on ubuntu 8.10 machine. But unfortunatly, I am failed. I checked the compile error, I guess the reason is that bonic (Android's verion libc) lack the define of div_t. I will try to build it later.

Android use YAFFS2 as its root filesystem.
For extract it, you can use a tool named "unyaffs", which can be found in http://code.google.com/p/unyaffs/.
This tool will extract content of image file into current directory. You'd better to create a new directory to hold them.
For making YAFFS2 image, please use binary tool mkyaffs2image. The tool is built in ./out/host/linux-x86/bin/mkyaffs2image
