QuestionLinking to library Pin

It looks as I have jumped the gun , again.

This bluetooth "stack" / library named "bluez" is somehow included in OS.
I can get some info about bluetooth devices using "system" calls.

That does not mean it can be used coding in C++.

I need to start from scratch and build the "bluetooth" library
or "bluetoothd".

1. download the latest "Linux stack" bluez-5.18 (?) - done
I am not sure why "they" call it "stack" , but that is not important.
2. follow "readme" and configure "it" (stack?) - partially done
3. run "make" and here I am stuck because it fails....

... tomorrow...















I probably asked this before, but .. here it goes
I have installed "bluetooth" library
apt-get install bluez libbluetooth-dev
and still getting this linker error



C_SPI_LCD.o ./src/MODULES/MODULE_1602/C_SSP.o ./src/MODULES/MODULE_1602/C_gpio.o ./src/VNA_1022_BASE.o -lgomp -lbluetooth -lstdc++ -lm -lgcc_s -lgcc -lc -lgcc_s -lgcc /usr/lib/gcc-cross/arm-linux-gnueabihf/5/crtend.o /usr/lib/gcc-cross/arm-linux-gnueabihf/5/../../../../arm-linux-gnueabihf/lib/../lib/crtn.o
/usr/lib/gcc-cross/arm-linux-gnueabihf/5/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lbluetooth
makefile:80: recipe for target 'VNAR_19321' failed
collect2: error: ld returned 1 exit status
make: *** [VNAR_19321] Error 1
"make all" terminated with exit code 2. Build might be incomplete.


The Cross G++ Linker has an option "-lbluetooth" but I only specify "bluetooth" , without the "-l"

I did try to locate bluetooth



jim@jim-desktop:~$ find -name "bluetooth"
find: ‘./.cache/dconf’: Permission denied
find: ‘./.dbus’: Permission denied
find: ‘./.config/configstore’: Permission denied
jim@jim-desktop:~$ sudo find -name "bluetooth"
[sudo] password for jim: 
jim@jim-desktop:~$ sudo find -name "*bluetooth"
jim@jim-desktop:~$ sudo find -name "*bluetooth*"

./.cache/upstart/indicator-bluetooth.log.1.gz
./.cache/upstart/indicator-bluetooth.log.6.gz
./.cache/upstart/indicator-bluetooth.log.7.gz
jim@jim-desktop:~$ 


Here are my questions / comments :

1. apparently the IDE adds the
"-l" to link to library - find with me.

2. Do I have to specify directory using "-L" and how do I find it using Linux?

3. It looks as there are no conventions as far as naming the library - some sources quote "libbluetooth"

Thanks
