I installed Mac OS package on macbook (late 2013). DRSOsc starts to write file but freezes; need to be restarted to restore connection with DRS4 evaluation board (ordered Aug 2011).
DRSOsc seems broken on OSX 10.9. I'm working on this right now. Some of the problems are related to wxWidgets, so I'm waiting for a new version running stably under OSX 10.9. The compilation problem related to "strlcpy" comes from the fact that OSX 10.9 now comes with its own version of that function, while all previous versions did not. So simply removing strlcpy.h/c from the project fixes that.
There will be a new version of DRSOsc next month which fixes all this problems, so just stay tuned.
