'make: Interrupt/Exception caught' when building an empty project
The problem was caused by something in my PATH. When I removed C:\Program Files (x86)\Git\bin\ from my path, eclipse would build. To isolate the problem, I used a .bat file to set the PATH to something simpler, like this:
set PATH=C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.externaltools.arm-none.win..... C:\Ac6\SystemWorkbench\eclipse.exe
Edit: I found another post here http://www.openstm32.org/tiki-view_forum_thread.php?comments_parentId=769&topics_offset=8 where Git in the PATH cuased other problems.
