How to identify library used by GCC linker ?

I am trying to use Linux command, hence my question is posted here, to physically verify / identify library used by GCC linker.
I have looked at GCC linker verbose output and it really does not tell me much, only that library "bluetooth" is set as "l" liked option - lbluetooth.

This syntax shows all object files associated with "bluetooth":

jim@jim-desktop:~$ ldconfig -p | grep "bluetooth"

jim@jim-desktop:~$ ldconfig -p | grep "bluetooth"
libgnome-bluetooth.so.13 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgnome-bluetooth.so.13
libbluetooth.so.3 (libc6,x86-64) => /usr/local/lib/libbluetooth.so.3
libbluetooth.so.3 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libbluetooth.so.3
libbluetooth.so.3 (libc6,x86-64) => /usr/lib/libbluetooth.so.3
libbluetooth.so.3 (libc6) => /usr/lib/i386-linux-gnu/libbluetooth.so.3
libbluetooth.so (libc6,x86-64) => /usr/local/lib/libbluetooth.so
libbluetooth.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libbluetooth.so
libbluetooth.so (libc6,x86-64) => /usr/lib/libbluetooth.so

Is there an option to narrow down the ldconfig / grep to be able to retrieve only file(s) associated with the application ?

probably you need to command ldd

Use linker -Wl,-Map=myfile.map option

can you show me an example? How does it work?

Example?
Not really , just added the option to the linker.
It creates the named file.
It is pretty big and I have not analysed it in its entirety, just part.
But I now know the exact library x.so files linked to the application.
I may eventually have to rename them...
