# prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-gdb out/target/product/smdkc110/system/bin/bluetoothd

$gdb set solib-absolute-prefix $(Android SMDK PATH)/out/target/product/smdkc110/symbols

$gdb set solib-search-path $(Android SMDK PATH)/out/target/product/smdkc110/symbols/system/lib$:(Android SMDK PATH)/out/target/product/smdkc110/symbols/system/lib/bluez-plugin

$gdb target remote :5039
