NullPointerException (on Mac OS) #10

After compiling with "ant" I get the following NullPointerException (on the splash screen it says "Loading module simulatorProvider")

Please look at the README.MD and follow the installation instructions. Let me know if that worked.

moritzmhmk commented 10 years ago

following the instructions does NOT fix the issue...

mpue commented 10 years ago

Please update, build again and let me know, what the thrown RuntimeException message is.

Hi,

the installation comands in the readme are wrong:

instead of cp -R models/ ~/.BlackBoard cp -R symbols/ ~/.BlackBoard cp -R parts/ ~/.BlackBoard cp -R datasheets/ ~/.BlackBoard cp -R simulators/ ~/.BlackBoard

it should be:

cp -R models ~/.BlackBoard cp -R symbols ~/.BlackBoard cp -R parts ~/.BlackBoard cp -R datasheets ~/.BlackBoard cp -R simulators ~/.BlackBoard

I just cloned the repo again and used above commands - works! :)
