Hi!
This morning, in an attempt of auto-encourage myself, I thougth I was
going to be able to compile the l2test application by my own, only from
the l2test.c source and having all the required libraries properly
installed... Of course I couldn't (crying). My fatal sin is that I'm
learning programming, communications, bluetooth and Linux, all the same
time, and all the same way (you can see that way). I hope don't bother
you trying to justify myself of asking the following question:
?Could you give me some ligth in the points to consider while compiling
a user-made source like the l2test application? I want to do this way
only for learning pourposes, in order to glimpse a bit the whole picture.
I'm getting errors of type "undefined references" like the following
linking l2captest (libtool)
linking l2captest (gcc)
/home/soraberri/Desarrollo/estudioC/l2captest/src/l2captest.c:222:
undefined reference to `strtoba'
l2captest.o(.text+0x680):/home/soraberri/Desarrollo/estudioC/l2captest/src/l2captest.c:222:

undefined reference to `str2ba'
*** Exited with status: 2 ***
Theese functions are defined in bluetooth.h as you know. I thougth I
should link with the -L /lib/modules/2.6.9-1.667/kernel/net/bluetooth/
flag, but there is the same output.
So this is the point.
Thanks for your advices

Hi Marcel
Yes, I appreciate very much your answer. You've solved the whole of my
actual doubts. You said you didn't understand why I don't just use
--enable-test from the bluez-utils configure script. Well that's easy:
because I didn't know about the possibility. Anyway, it's helpful for me
in order to learn.
Thanks Marcel

don't link anything against any kernel stuff from userspace. This will
never work. I don't understand why don't you use --enable-test from the
bluez-utils configure script. However what you are searching for is:
gcc l2captest.c -o l2captest -lbluetooth

Marcel
