Instructions on how to apply patches are located here:
http://www.rockbox.org/twiki/bin/view/Main/WorkingWithPatches

This assumes that you have a development environment already set up with the Rockbox source checked out of CVS and the Gnu toolchain in place to compile for your desired target. If you don't have this set up you may want to take a look at:

I try to apply a patch but it says

C:\rockbox>patch --binary -p0 < doom_scroll3.patch
'patch' is not recognized as an internal or external command,
operable program or batch file.

What is wrong?

You don't have patch.  It should have been included with your cygwin install.  Are you sure you have cygwin working?

If you're really using Cygwin, you would see a bash prompt such as

$

, not the Windows/MS-DOS prompt such as

C:\rockbox>

Are you sure you're actually running the Cygwin shell when trying to patch/compile?

Not always:

C:\Documents and Settings\mike.EEB\My Documents>patch --binary -p0 < lock.c
patch unexpectedly ends in middle of line
patch: **** Only garbage was found in the patch input.

You can also change the Windows PATH

But yeah, I'm guessing he either didn't install Cygwin, isn't running Cygwin or didn't correctly install the needed components.

Again problems:

Do I do it right or something wrong and what I have to write next
Lame questions but i cant get it.

As stated in the patching guides, did you then try this increasing the p value 1-by-1 up to 4 or 5?  That sometimes will handle this.

Otherwise, try putting a copy of the patch in each of the the folders holding the files to be patched, and try patching again (I can't recall right now if it also has been helpful to run the patch command from within those directories as well).

[bluebrother]

as the screenshot says you're in the wrong directory. patch expexts the file it displays (apps/plugins/doom/d_event.h) and it hasn't found it, indicating that you need to change in that subfolder from what you can do a "ls apps/plugins/doom/d_event.h" successfully. Increasing the p value won't help in that case. (Another possibility would be that this file is missing from your source tree but if you have an actual cvs source tree this shouldn't happen).

[eK3eKyToPa]

I'm absolutely lame on cygwin so i'll thx you if tell me what exactly to write and change the directory to apps/plugins/doom/ or what it need to be.

[bluebrother]

I can't write "exactly" what to do as I don't know your file system structure. What subfolders do you have inside of the folder you're in? I guess cvs generated a "rockbox" or "rockbox-dev" subfolder to which you need to change before. Or: before running patch make sure your actual folder contains the subfolders "apps", "firmware", "tools" (and most probably some more).

Also, why don't you try the vmware image? It comes with a preconfigured environment and there are quite some people around who use it and most probably can make a lot more assumptions than in this case.

Hello, I have a problem with installing one of the patches..
This is what the top of my patch says:

ok and this is how far I am at...
I open cygwin
$ cd g:\.rockbox
then it show
kevin@kevin-####(numbers) cygdrive/g/.rockbox
then when I type in patch < mypatch.diff it gives me an error saying "Batch: Patch: file directory not found." or something similar to that. Do you know what I did wrong? is it because I placed the mypatch.diff file in the wrong place? if so where do I place it? if not can you please help me resolve this problem.

Thank You.

Great, but it is not OK to copy and paste messages from the forums and PM them to me.

Post the actual error message if you want a good answer.

But I'm going to guess you don't have patch installed in cygwin.

Hahahahaa awesome.

$ cd g:\.rockbox

You're doing it wrong. You patch against the source code, not against a compiled build. Read http://www.rockbox.org/twiki/bin/view/Main/SimpleGuideToCompiling

I'm sorry about that. but how do I have a patch installed in cygwin.
I read the the stuff on the compiling website and the patching website.. but I still don't understand. = = can you guide me or give me an example?
