Hey guys, I've been using arduino for at least a year now and just recently the programming environment has stopped compiling anything.
If I click 'compile', the progress bar stops about halfway across. I have left it in this state for more than an hour with no changes.
I do not get any error codes-just a stuck progress bar!
I am using windows 7. Changing the sketch does not affect the problem.
***EDIT: just noticed that after 2 hours of waiting for it to compile, the progress bar reads 'done compiling' and the black 'status' bar below it reads:
"C:\Users\Max\Documents\Personal\Ickle creations\RC\Controllers\Crius stuff\arduino-1.0.4\hardware\tools\avr\bin\avr-ar: unable to rename 'core.a'; reason: File exists"
Help is much appreciated.
