Mac mkyaffs2image binary Re: HOWTO: Roll Your Own Firmware
Here’s a Mac (intel 32bit snow leopard) built binary of mkyaffs2image
I have only tested it so far that it runs. Use at your own peril.
Based on the source from http://code.google.com/p/fatplus/downloads/list .
Got it to compile by adding the following to devextras.h
#if defined(__APPLE__) || defined (__FreeBSD__)
typedef long long loff_t;
No luck on finding or building a mac binary of unyaffs so far. However, a Windows binary can be found at http://boomtopper.blogspot.com/2009/10/unyaffs-windows-binary.html
