Hi,

I'm having some weird trouble with a file's modification date and the
debugger.
I recently moved some source files from a network drive to a local drive.
Now, one of the files (and only one as far as I can tell) is giving an error
that I can't get rid of:

"Invalid file modification date.
The modification date for the file "xxx" does not match its date stored in
the debugging information. <snip>"

The program is behaving strangely in the code from this source file.
Debugging is doing strange things, recognizing part of the source file and
recognizing breakpoints in part, but not in others. I've tried "Remove
object code" and "Synchronize modification dates", and "Reset Project Entry
Paths" (not that I know what that does), but to no avail.

The source file in question (ie that's in the project and that comes up in
the debugger) seems to be the correct one, ie in the correct location.

Anyone have any ideas?

Thanks,
Michael

Trash your sym files, delete the source file and add it back again to
your project. I think that will resolve all things... but let me know
if it doesn't there may be other things to try.

But the sym file information is for a different file and that is why you
are getting the error. I've seen this before when moving files,
(especially if the project is open) It probably still has some cache
set for the network drive.

I'm not sure what the problem is, ultimately it is Metrowerks problem
to solve even if it is an OS quirk, so please report this to
Metrowerks. Even if the fix is simple. If enough people report it then
it will be given the highest priority.

First I tired: 1a) remove source file from project 1b) "remove object code"
from project 2) close CW 3) delete the output app for the project targe in
question (ie the package that contains the sym file) 4) delete the target
settings file for the project 5) start CW 6) put source file back into
project 7) rebuild project --- same problem!

Then I tried 1) remove source file from project 2) copy the source file
contents into a new source file 3) add the new source file to the project 4)
quit CW 5) delete sym file itself from output app package 6) restart CW 7)
recompile ---- it worked!

Maybe a corruption in the source file itself? Bad bit in Finder data? In any
case, this reminded me that I've had to do the same kind of thing a few
times over the past few years, both on CW Mac and MS VC++ Windows.

I'm still getting weird behavior in the program, but now it's probably due
to my buggy code!

Thanks,
Michael

good luck, and thanks for sticking with it and finding the fix.
