cmake-avr - a cmake toolchain for AVR projects

Testing the example provided

The toolchain was created and tested within the following environment:

Linux

Windows XP

Windows 7

OS X

Note: If building in a Windows environment, you need to extent the values of the environment variable PATH to the location of the binaries, especially to find make. To enable a more general approach to different Windows toolchains, the variable AVR_FIND_ROOT_PATH needs to be defined. Tested was it with the following setup (XP):

PATH=...;d:/Program Files/Atmel/Atmel Studio 6.0/extensions/Atmel/AVRGCC/3.4.1.81/AVRToolchain/bin;...
AVR_FIND_ROOT_PATH="d:/Program Files/Atmel/Atmel Studio 6.0/extensions/Atmel/AVRGCC/3.4.1.81/AVRToolchain/avr"

Issue within Windows 7 environment With Windows 7 (64bit) and the Atmel Studio 6.2 setup, make.exe now resides differently. It also crashes during the cmake generation process, just after the simple examples to test the compiler (try_compile(...)) ran through. The why and avoidance of this is currently unknown to me. I didn't try to use a cygwin make as a substitute yet.

After getting the project

git clone git@github.com:mkleemann/cmake-avr.git /path/to/clone/in

you just need to run the following commands

mkdir -p /path/to/some/build/dir
cd /path/to/some/build/dir
cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/clone/in/generic-gcc-avr.cmake /path/to/clone/in/example
make

For Windows use:

cmake -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=/path/to/clone/in/generic-gcc-avr.cmake /path/to/clone/in/example

This just creates the example, but does not upload it. For all possible targets, you need to run

make help

after running the cmake command.
