cmake give undefined reference

Question

Hi I'm trying to use bluez source code to control some stuff in my code.

In my cmake I first start doing instruction like

include_directories(${CMAKE_SOURCE_DIR}/../bluez/attrib/)

then

aux_source_directory(${CMAKE_SOURCE_DIR}/../bluez/attrib/ SRC_BLUEZ_ATTRIB_LIST)

and finaly add SRC_BLUEZ_ATTRIB_LIST to my add_executable

But I still have

undefined reference to gatt_connect(char const*, char const*, char const*, char const*, int, int, void (*)(_GIOChannel*, _GError*, void*), _GError**)

Any suggestion?

What is the content of `SRC_BLUEZ_ATTRIB_LIST` (`MESSAGE(${SRC_BLUEZ_ATTRIB_LIST})`)? — Peter Petrik, Jul 30 '14 at 05:00
path to sources files from the attrib folder in bluez source — user1796260, Jul 30 '14 at 08:14

Use extern "C" in your c++ source file

extern "C" {
   #include "gatttool.h"
}
