Gdbus-codegen not found


I am trying to cross-compile my package with SDK, but I am still getting this error:

[ 1%] Generate DBus ‘org.bluez.GattCharacteristic1.xml’
/bin/sh: 1: /openwrt-sdk-omnia/staging_dir/host/bin/gdbus-codegen: not found
make[6]: *** [src/bluetooth/org-bluez-gattcharacteristic1.c] Error 127

I checked the file mentioned as “not found” and it is there, so problem is somewhere else. Could you please someone help me with how to solve that error?

Thank you for your response.
