[yocto] Error applying patch - openvswitch

[Rajasekaran, Monica]

Hi,

In order to make source code changes to openvswitch present under layer meta-virtualization, I did the following:


-        The file I want to change is ofproto.c - copy it into data/users/mrajase/extra and make all the changes there.

-        Create a patch file between the original file and this updated file (this error is with using "git diff --no-prefix". I also tried by using diff -Naur). So now I have a locally present patch file.

-        Copy the patch file into repo/poky/meta-virtualization/recipes-networking/openvswitch/files/

-        Edit repo/poky/meta-virtualization/recipes-networking/openvswitch/openvswitch_2.0.0.bb and add the line  SRC_URI = "file://openvswitch-Firsttt.patch;patch=1 \"

-        Clean and build the image again.


This is my error:

ERROR: Command Error: exit status: 1  Output:
Applying patch openvswitch-Firsttt.patch
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

Any help?

Thanks,
