Build the package from apt-cacher-ng feed

1. Some variables - your setup will vary

   BASEDIR=/home/bill/Downloads/hardware/nanopi-r5c/custom-software
   ACNG_VERSION=3.7.5
   TARGET=rockchip-armv8
   PLATFORM=aarch64_generic
   SNAPSHOT=no
   if [ "${SNAPSHOT}" == yes ]; then
     OPENWRT_SDK=openwrt-sdk-${TARGET}_gcc-12.3.0_musl.Linux-x86_64
     DOWNLOAD_URL=https://downloads.openwrt.org/snapshots/targets/rockchip/armv8
   else
     OPENWRT_VERSION=25.12.4
     OPENWRT_SDK=openwrt-sdk-${OPENWRT_VERSION}-${TARGET}_gcc-14.3.0_musl.Linux-x86_64
     DOWNLOAD_URL=https://downloads.openwrt.org/releases/${OPENWRT_VERSION}/targets/rockchip/armv8
   fi
   

2. Download SDK for your board. Note this is only an example. You have to select and download the SDK for your particular board.

   cd ${BASEDIR}
   wget ${DOWNLOAD_URL}/${OPENWRT_SDK}.tar.zst
   

3. Extract SDK

   tar --zstd -xf ${OPENWRT_SDK}.tar.zst
   

4. Use the provided feed

   • a. Enable local modifications

     • Download apt-cacher-ng feed from github

       git clone https://github.com/vasvir/openwrt-packages.git
       

     • Edit feeds.conf.default in the sdk downloaded and extracted before. Use the expanded version and not the BASEDIR variable. Add

       src-link local ${BASEDIR}/openwrt-packages
       

   • b. Or Use the feed directly from github

     • Adjust feeds.conf.default. Add

       src-git local https://github.com/vasvir/openwrt-packages.git
       

5. Edit the Makefile in openwrt-packages/apt-cacher-ng/

   • Update PKG_VERSION
   • Update PKG_HASH it is the Sha256 of the orig.tar.xz

6. Configure local packages

   cd ${OPENWRT_SDK}
   ./scripts/feeds update -a
   # required library c-ares
   ./scripts/feeds install libcares
   ./scripts/feeds install apt-cacher-ng
   make menuconfig
   

   menuconfig should show apt-cacher-ng under Network/Web Servers/Proxies [1]

7. Install local signing keys

   ./staging_dir/host/bin/usign -G -s ./key-build -p ./key-build.pub -c "Local build key"
   

8. Build package [2]

   make -j5
   

   This takes some time though, around 4m when everything is already built except our package.

9. Copy apk file for apt-cacher-ng over to openwrt router.

   rsync -av bin/packages/${PLATFORM}/local/apt-cacher-ng-${ACNG_VERSION}-r1.apk root@openwrt:
   

10. Install the apt-cacher-ng package and its dependencies [3]

    ssh root@openwrt
    apk add --allow-untrusted ./apt-cacher-ng-${ACNG_VERSION}-r1.apk
    

11. Configure apt-cacher-ng service

Create the CACHEDIR, LOGDIR and /var/run/apt-cacher-ng/ directories. You need probably an external disk already setup for cachedir and logdir.

EXTERNAL_DIST_MOUNTPOINT=/mnt/intenso-4t-usb3
CACHEDIR=${EXTERNAL_DIST_MOUNTPOINT}/var/cache/apt-cacher-ng
LOGDIR=${EXTERNAL_DIST_MOUNTPOINT}/var/log/apt-cacher-ng
mkdir -p ${CACHEDIR}  ${LOGDIR} /var/run/apt-cacher-ng/
chown -R apt-cacher-ng:apt-cacher-ng ${CACHEDIR} ${LOGDIR}

Edit /etc/apt-cacher-ng/acng.conf to configure the cachedir and logdir.

1. Restart the service

   /etc/init.d/apt-cacher-ng restart
   

TODO

• Autoconfigure step: Configure apt-cacher-ng service.

Troubleshooting

This is possible only if you have followed option a) in the "Use the provided feed" step.

friendly commands

• make V=s
• make V=s package/feeds/local/apt-cacher-ng/clean
• make V=s package/feeds/local/apt-cacher-ng/compile
• make V=s package/feeds/local/apt-cacher-ng/install

[1] Buildroot Makefile problem.

Adjust ${BASEDIR}/openwrt-packages/apt-cacher-ng/Makefile and retry

./scripts/feeds uninstall apt-cacher-ng
rm -rf  build_dir/target-${PLATFORM}_musl/apt-cacher-ng-${ACNG_VERSION}/
./scripts/feeds install apt-cacher-ng
make menuconfig

This may help if you need to update dependencies

./scripts/feeds update -a

[2] Package CMakeLists.txt problem.

Adjust /home/bill/Downloads/hardware/linksys1200ac/openwrt-packages/apt-cacher-ng/patches/000-add_install_target.patch and retry:

• setup once:

  • download the apt-cacher-ng source

    wget http://ftp.us.debian.org/debian/pool/main/a/apt-cacher-ng/apt-cacher-ng_${ACNG_VERSION}.orig.tar.xz
    

  • extract it

    tar -xJf apt-cacher-ng_${ACNG_VERSION}.orig.tar.xz
    

  • rename and copy it to have an easy diff target

    mv apt-cacher-ng_${ACNG_VERSION} a
    cp -a a b
    

• edit test cycle

  • modify b - produce patches for CMakeLists.txt and move them over to /home/bill/Downloads/hardware/linksys1200ac/openwrt-packages/apt-cacher-ng/patches/000-add_install_target.patch

    diff -ur a b > ${BASEDIR}/openwrt-packages/apt-cacher-ng/patches/000-add_install_target.patch
    

  • build

    rm -rf build_dir/target-${PLATFORM}_musl/apt-cacher-ng-${ACNG_VERSION} 
    make V=s
    

[3] Installation problems in postinst.

Adjust Buildroot Makefile and retry:

ssh root@openwrt opkg remove apt-cacher-ng
./scripts/feeds uninstall apt-cacher-ng
rm -rf build_dir/target-${PLATFORM}_musl/apt-cacher-ng-${ACNG_VERSION}
./scripts/feeds install apt-cacher-ng
make -j5
rsync -av bin/packages/${PLATFORM}/local/apt-cacher-ng-${ACNG_VERSION}-r1.apk root@openwrt:
ssh root@openwrt apk add --allow-untrusted ./apt-cacher-ng-${ACNG_VERSION}-r1.apk
