Using the FPC console IDE. When I define a typed array with limits, ie.: type tbarray=array[0..1023] of byte; var foo:tbarray; ...I can view the contents of in the watch window (like "foo[2]") without problems. But if I define it as a dynamic array: type tbarray=array of byte; var foo:tbarray; ... setlength(foo,1024);...then trying to view the array ("foo[2]") in the watch window shows up as "Cannot perform pointer math on incomplete types, try casting to a known type, or void *". I've tried casting like byte(foo[2]) and byte^(foo[2]) but I must be doing it wrong as those aren't working. What is the proper way to cast dynamic arrays so that I can inspect them in the watch window?
Dynamic arrays are actually *pointer* to arrays. The compiler hides this fact from you because it automatically dereferences the pointer when you use an index: foo[i] will be automatically expanded to foo^[i] But the debugger is not able to do this. So you need to write foo^[i] when you want to examine this value in watch window or other debug windows. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
