Sorry for not responding earlier. I do not read this list regularly.

The values I supplied for the suggested bbappend all come from the version of the apache2 recipe that is on master of the openembedded repository.
If you change the version from 2.4.54 to 2.4.52, then yes, you will have to change the checksums as well to match. It also means that you may need to apply other patches (based on what the recipe for apache2 looks like on the Honister branch).

Looking at your error messages below, they refer to a recipe called “smith-nephew-cp-lwb5”. I do not know what that is (though the version matches apache2’s…)

Peter, so here’s my current bbappend file for Apache 2.4.52 which is included with honester:

        FILESEXTRAPATHS_prepend := "${THISDIR}/${BPN}:”

        LIC_FILES_CHKSUM = "file://LICENSE;md5=bddeddfac80b2c9a882241d008bb41c3”

        PV = <file://LICENSE;md5=bddeddfac80b2c9a882241d008bb41c3”%0b%0b       %20PV%20=%20> “2.4.52"

        SRC_URI += "file://0008-Fix-perl-install-directory-to-usr-bin.patch \
            file://0009-support-apxs.in-force-destdir-to-be-empty-string.patch \
            file://0001-make_exports.awk-not-expose-the-path.patch”
        SRC_URI_remove = "file://apache-configure_perlbin.patch”

        SRC_URI[md5sum] = <file://apache-configure_perlbin.patch”%0b%0b       %20SRC_URI[md5sum]%20=%20> “861b43073ab416d689f1fc4dfa087711"
        SRC_URI[sha256sum] = “eb397feeefccaf254f8d45de3768d9d68e8e73851c49afd5b7176d1ecf80c340”

And the current build error:


        ERROR: smith-nephew-cp-lwb5-2.4.52-r0 do_populate_lic: QA Issue: smith-nephew-cp-lwb5: LIC_FILES_CHKSUM points to an invalid file: /ct/yocto/imx-       5.4.70/build/tmp/work/imx6ulevk-poky-linux-gnueabi/smith-nephew-cp-lwb5/2.4.52-r0/smith-nephew-cp-lwb5-2.4.52/LICENSE [license-checksum]

My gut feeling is that the SRC_URI[mdtsum] and SRC_URI[sha256sum] and out of whack because I needed to switch from 2.4.54  to  2.4.52 of apache.  You supplied the SRC_URI[sha256sum] based on a 2.4.54 version of Apache?  and I filled in the SRC_URI[md5sum] based on what bitable told me it should be. If you can tell me how to get the correct SRC_URI[sha256sum] for apache 2.4.52 I think I can get past this error.

Thanks, Jim

If you can tell me which file you took it form that would be helpful and I can go and get that MD5 sum from Honiker tree — whatever file it was that I should get it from.

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).

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.
