patch files

[Stephen Ecker]

I'm not certain if this is isar specific or just bitbake:  I have a patch file I've added to my layer but my build keeps erroring stating that it can't find the file to patch.  the target file is in a recipe of the same name but in a different layer.  to where should the patch file point in its second line?

thanks

Hello.
If you have some <recipe>.bb in some layer and <files/your.patch> for
it in your layer, you should also create in your layer
<recipe>.bbappend with the contents like:

| FILESEXTRAPATHS:prepend := "${THISDIR}/files:"
| SRC_URI:append = " \
| file://your.patch \
| "

That's exactly what I did, but it always says that it could not find the file to patch.  

What should the two first lines of the path show was the directory?

[Stephen Ecker]

Bb shows the directories in which it looked for the patch file... It found that.  It's the file to patch that quilt can't find: 

NOTE: Applying patch 'something.patch' (../meta-something/recipes-core/recipe-name/files/something.patch)

....

can't find file to patch at input line 3

perhaps you used the wrong -p or --strip option? 

...

It does not show the directories in which it tried to find the target file 

Maybe you could provide me an example patch file?

This looks not related to Isar or bitbake. Your patch simply doesn't
fit sources you want to apply it to.

I made the patch file with the exact two files I'm trying to patch:

diff -u ../../../isar-cip-core/recipes-initramfs/initramfs-crypt-hook/files/encrypt_partitions.script encrypt_partitions.script > encrypt_partitions.script.patch
