[yocto] Error applying patch - openvswitch

[Rajasekaran, Monica]

Hi Khem,

I will try it using quilt and get back.

I don’t know why the patch file turns out empty if both the original and updated file are in the same location. It was good when they were in different locations. I put them in the same place because of path related confusion which was causing build errors.

Thanks,
Monica

this patch is empty. Secondly, make sure that patch is generated relative to S

if you were not doing devtool workflow which I recommend to follow. You can also go into the ${S}
and generate the patch using quilt.

quilt new your.patch
quilt add ofproto.c
make changes to ofproto.c
quilt refresh
then copy patches/your.patch to metadata area and apply it by adding it to SRC_URI

Hi Ross,

I have attached the related files.

openvswitch_2.0.0.bb is the recipe file and I have included my patch there as file://openvswitch-Firsttt.patch;patch=1 \<file:///\\openvswitch-Firsttt.patch;patch=1%20\>.

openvswitch-Firsttt.patch is my patch file.

Ofproto.c is the original code.

Ofproto_updated.c is the one with a couple of my changes and print statements.

Thanks,
Monica

Without sharing your recipe or the patch, nobody can help.  Check that the SRC_URI correctly contains the patch, that it ends with .patch or .diff to be applied as a patch automatically, and verify that you actually rebuilt the recipe.

The folders in tmp/work on my source machine don’t have today’s date as last modified.

Hmm… I don’t know what might be the mistake with applying the patch.

Thanks,
Monica

After applying the patches, I brought up my openvswitch which works correctly alongside the controller but I don’t see any of the print statements I added to view the changes inside. Is there a way to check the updated source code with my patch in the target machine ?

Not really, but looking in the work directory (tmp/work) will tell you if it got applied.
