[Gumstix-users] Fix libbluetooth linking to save about 100 kbytes

[Leonard S. <lsa...@co...>]

Hi folks,

I believe it's possible to recover 100 kibytes of onboard flash by 
un-replicating the bluetooth shared object library.  The first hint of 
the replication is a complaint by ldconfig that the library was not 
symlinked.

# cd /usr/lib
# ls -lsa libbluetooth*
  51 -rwxr-xr-x    1 root     root        52456 Mar  4  2005 
libbluetooth.so   
  51 -rwxr-xr-x    1 root     root        52456 Mar  4  2005 
libbluetooth.so.1 
  51 -rwxr-xr-x    1 root     root        52456 Mar  4  2005 
libbluetooth.so.1.0.10
# rm libbluetooth.so libbluetooth.so.1
# ln -s libbluetooth.so.1.0.15 libbluetooth.so.1
# ln -s libbluetooth.so.1.0.15 libbluetooth.so
#  ls -lsa libbluetooth*
   0 lrwxrwxrwx    1 root     root           22 Dec 31 19:02 
libbluetooth.so -> 
libbluetooth.so.1.0.10                                                          

   0 lrwxrwxrwx    1 root     root           22 Dec 31 19:02 
libbluetooth.so.1 -> 
libbluetooth.so.1.0.10                                                        

  51 -rwxr-xr-x    1 root     root        52456 Mar  4  2005 
libbluetooth.so.1.0.10

After making this change, I have successfully logged into the gumstix 
from my workstation through the bluetooth link, as well as running a few 
hcitool queries and l2ping tests.  This is not a *thorough* test, but 
the successful execution of these small tests shows that 
libbluetooth.so* doesn't have some unique requirement of being 
thrice-replicated to function.

The replication exists in the buildroot that I downloaded and built 
(after fixing the umn.dl.sourceforge.net openobex download problem) 
today.  I will attempt to find out how to rectify this little 
wastefulness in the original build scripts and makefiles, and generate a 
set of diffs.
