I have never built systemd-hwdb before, but when I do it fails like this:
----------------------------
target: systemd-hwdb.install
----------------------------
install: creating directory
'/src/build/platform-ec2k/packages/systemd-hwdb-1/usr/lib/udev'
/src/build/platform-ec2k/sysroot-host/bin/systemd-hwdb: error while loading
shared libraries: libsystemd-shared-248.so: cannot open shared object file:
No such file or directory
make: *** [/src/build/rules/systemd-hwdb.make:26:
/src/build/platform-ec2k/state/systemd-hwdb.install] Error 127
I find this file here:
jringle@-arm-v7a-linux-gnueabihf:~/build$ find
/src/build/platform-ec2k/sysroot-host/ -name libsystemd-shared-248.so
/src/build/platform-ec2k/sysroot-host/lib/systemd/libsystemd-shared-248.so
