In order to run the bluetooth C program on my ubuntu desktop I installed the libbluetooth-dev using

sudo apt-get install libbluetooth-dev

Then I compiled the code with

gcc -o simplescan simplescan.c -lbluetooth

and it executed just fine. However when I tried to cross compiled it for Android using

arm-linux-gnueabi-gcc -o simplescan simplescan.c -lbluetooth

It gave me the error

/usr/lib/gcc-cross/arm-linux-gnueabi/4.7/../../../../arm-linux-gnueabi/bin/ld: cannot find -lbluetooth 
collect2: error: ld returned 1 exit status​

I noticed there was similar post here: Bluetooth programming in Linux - cross compiler issue

But seems like it didn't give a solution, I am still confused how to install the libbluetooth-dev support for the cross compiler.

  • The answer does in fact give a solution. You should look at it again and read it more carefully. – Ken White Mar 27 '17 at 02:33

  • Probably your toolchain doesn't shipped with bluetooth development library. So you need to cross compile BlueZ first (with dependency) and cross compile with according sysroot. – Parthiban Mar 27 '17 at 11:52
  • Try compiling BlueZ for android. URL from google, http://wiki.beyondlogic.org/index.php?title=Cross_Compiling_BlueZ_Bluetooth_tools_for_ARM – Parthiban Mar 27 '17 at 11:54

You cannot link the libbluetooth library that was compiled for a different architecture. You need to build the libbluetooth library for the architecture your application will be build for.
