No, you are supposed to copy the suggest text for the bbappend verbatim, with the exception of the SRC_URI[md5sum] which need to be corrected to match the actual MD5 sum (which bitbake will tell you when you try to build). The suggested additions/deletions for SRC_URI in the bbappend I suggested should be correct as specified, based on the differences between the apache2 recipe in Zeus and master. You will also need to copy the three new patch files from master of meta-webserver, and any of the other patches that have been updated between Zeus and master. Changing PV takes care of the actual update of the code to the new version (since it determines which tar ball is fetched from upstream).

H Peter. I have t admin, looking at the above bbappend, its really confusing to me. I’ve looked at some of the documents on bitbake and I just can’t find anything to teach me how to put a bbappend together to accomplish upgrading an application.

Like for example:

SRC_URI += "file://0008-Fix-perl-install-directory-to-usr-bin.patch

I believe this one should be:   

SRC_URI += file:/usr/bin/patch

The next one:

file://0009-support-apxs.in-force-destdir-to-be-empty-string.patch

I’ve no idea what this one will nee to be.

And this one:

file://0001-make_exports.awk-not-expose-the-path.patch

I don’t know what is supposed to go here either.

Then the SRC_URI_remove will be a pointer to the file containing the patches containing the diff’e between apache 12.4.1 and apache 2.4.54 ? I don’t think you can create a single patch file containing diff’s between multiple versions can you? I think it would have to be diff’s between apache 2.4.41 and 2.4.42. Right. Totally confused as to what to do here.

Any further help appreciated.

If you know of a resource for me to reference please pass it on. I just don’t see any clear documentation that explains how to construct a bbappend file.

Thanks, Jim
