Bug#785384: arduino-mk: attiny example does not build

[Michal Suchanek]

Package: arduino-mk
Version: 1.3.4-1
Severity: normal

Hello,

I downloaded some random core file for attiny from here: https://code.google.com/p/arduino-tiny/

I first tried to place the core file in /usr/share. However, arduino-mk
would not pick it up so I installed it in ~ instead.

I also had to
export ARDMK_DIR=/usr/share/arduino/
otherwise the scripts would shriek numerous errors.

Finally I found that all these errors are merely cosmetic.

In the end arduino-mk does not set -mmcu for the compiler.

I tried with arduino-core 1.0 and 1.5. It seems arduino-mk only works with arduino 1.0 core definitions.

Either way the final compiler error is the same

Unfortunately the attiny core files are not packaged in Debian anywhere I could find them

Can you recommend a core file that works with the Debian tools and put that in a readme or something?

Thanks

Michal
