I had to set up my PC from scratch and now, having reinstalled SlickEdit 2012 (v126.96.36.199 64-bit) I can build an app as before, but when calling the debugger (F5) I get the message:
Error starting debugger: GNU debugger (gdb) not found
Two things: VS has an internal debugger and secondly, gdb is also available - in the cygwin\bin folder as gcc. This folder is also part of the PATH environment variable. Why is none of those found?
