Likely libTest.so is built incorrectly and [email protected] is ending up with an incorrect DT_NEEDED entry. Can you show the output of objdump -x lib/libTest.so and objdump -x $OUT/vendor/bin/hw/[email protected]? My guess is that SONAME in libTest.so is "out/target/product/xxx/obj/lib/libTest.so" and that gets copied into NEEDED in [email protected].
