##Buliding `binutils`, `gcc`, and `avr-libc` for the AVR system
Now we can make the critical stuff for compiling our firmware: `binutils`, `gcc`, and `avr-libc` for the AVR architecture. These allow us to build and manipulate the firmware for the keyboard.

For building the `avr-libc`, we have to specify the host build system. In my case it is `x86_64-unknown-cygwin`. You can look for build system type in the `gcc` configure notes for the proper `--build` specification to pass when you configure `avr-libc`.

We can either build our own, or use the precomplied binaries. The precompiled binaries don't play well with `cygwin` so it is better to build them ourselves. The procedure for the precompiled binaries is included at the end of this guide.
The `dfu-programmer` requires `libusb`. So let's go ahead and build that first.

- Try making sure your `PATH` variables are set correctly for both `Windows` and `cygwin`.
- Make sure the `dll` is named correctly.
- Do not extract it with `cygwin`'s `unzip` as it does not set the executable permission. If you did it anyway, do `chmod +x dfu-programmer.exe`.
- Still have problems? Try building it instead.
##Debugging Tools
These tools are for debugging your firmware, etc. before flashing. Theoretically, it can save your flash memory from wearing out. However, these tool do not work 100% for the Planck firmware.

### `gdb` for AVR
`gdb` has a simulator for AVR but it does not support all instructions (like WDT), so it immediately crashes when running the Planck firmware (because `lufa.c` disables the WDT in the first few lines of execution). But it can still be useful in debugging example code and test cases, if you know how to use it.

### `simulavr`
`simulavr` is an AVR simulator. It runs the complied AVR elf's. `simulavr` does not support the `atmega32u4` device... it does `atmega32` but that is not good enough for the firmware (no PORTE and other things), so you cannot run the Planck firmware. I use it to simulate ideas I have for features in separate test projects.

This one is a major pain in the butt because it has a lot of dependencies and it is almost always buggy. I will do my best to explain it but... it was hard to figure out. A few things need to be changed in the 'Makefile' to make it work in `cygwin`.
