Chapter 29. Problems applying a patch
Table of Contents
All patches provided by eCosCentric should apply cleanly to your specific version of eCosPro. On the rare occassion that a patch does not apply cleanly, here is a list of error messages and how to handle them. If you are still unable to apply the patch or do not see the error message listed here, please report this issue on the eCosCentric Bugzilla website.
29.1. Cannot find file
can't find file to patch at input line nnn. File to patch: No file to patch. Skipping patch. n out of n hunks ignored.
First make sure that you used the right patch command line, as shown above.
If that still did not work, try with a higher
n, up until maybe 6. To try without actually applying
the patch, add
--dry-run to the command line. With this
option the patch is not actually applied but you get all the messages as if
the patch were really applied. This allows you to determine whether there
would be any errors, without having to the files from backup every time.
When you no longer get the error messages about not finding the file
to patch, then you have found the right number for -p and you can repeat
the command without
--dry-run to actually apply the
29.2. Hunk FAILED
Hunk #n FAILED at nnn. n out of n hunks FAILED - saving rejects to file file.rej
This means that one or more changes, called hunks, could not be
introduced into the file. Occasionally this could be because the patch
was emailed or copied into a file and whitespace was either added or
removed. Try adding
--ignore-whitespace to the command
line to work around this.
If you still get errors, it is most likely the
patchfile was created for a version of
eCosPro that is substantially different from
the version you are using. In this event, please report this issue on the
29.3. Hunk succeeded
Hunk #n succeeded at nnn (offset n lines) and Hunk #n succeeded at nnn with fuzz n.
Usually there is no problem here and the patch could be applied completely.
This message usually means that the
originally created for a slightly different version of
eCosPro from the one you are using.
On rare occassions patch may think it applied the changes correctly but really did not. If something does not work and you think that the patch may have been applied incorrectly, please report this issue on the eCosCentric Bugzilla website.
29.4. Malformed patch
malformed patch at line nnn
This message means that the
patchfile is damaged.
If you copy-pasted the patch from somewhere, be careful not to modify or
damage it. A
patchfile contains spaces at the start of
lines and these often get lost in copy-paste. The safest mechanism is to
patchfile and save it somewhere locally.
If the browser does not download the
displays it instead, use
File -> Save to save a copy
29.5. Reversed patch
Reversed (or previously applied) patch detected! Skipping patch. Reversed (or previously applied) patch detected! Assume -R? [n]
This message usually means that a change in the patch is already contained in the file. The most common reason for this is that the version of eCosPro you are using already contains that patch or the patch was already applied. In this event do not apply the patch.
