I’ve just checked the SDK package, it looks like there is an error in the package feed configuration which I will need to track down.
So do this first:
sed 's/arm64-2102/arm64_2102/g' feeds.conf.default > feeds.conf
Try without this step:
./scripts/feeds install -a
This installs ALL packages from OpenWrt’s various collections (openwrt itself, packages, LuCI etc) into the SDK system, which would take quite a long time to compile.
If you are trying to compile a certain OpenWrt package which we don’t have, you can do:
$ ./scripts/feeds update -a
$ ./scripts/feeds search p190nd
Search results in feed 'packages':
p910nd A small non-spooling printer server
...
$ ./scripts/feeds install p910nd
$ make defconfig
$ sed -i 's/CONFIG_SIGNED_PACKAGES=y/CONFIG_SIGNED_PACKAGES=n/g' .config
$ make -j$(nproc)
make[1] world
make[2] package/compile
make[3] -C package/toolchain clean-build
make[3] -C package/toolchain compile
make[3] -C feeds/packages/net/p910nd clean-build
make[3] -C feeds/packages/net/p910nd compile
make[3] -C package/kernel/linux compile
make[2] package/index
After this, the compiled OpenWrt package (.ipk) will be in bin/packages/aarch64_generic:
$ find bin/packages/aarch64_generic/
...
bin/packages/aarch64_generic/packages/p910nd_0.97-9_aarch64_generic.ipk
If you are trying to add your own package, you can follow the guide at OpenWrt.org: “Hello, world!” for OpenWrt /Creating a package from your application
