交叉编译适用于 Android 的蓝牙 C 程序（blueZ）

Question

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.

Answer 1

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.
