Re: why is ldconfig needed after installation

The problem here is that *-n* implies *-N* which instructs *ldconfig* not
to rebuild the cache.

The following files exist in */usr/local/lib*:

   - file *libmy.so.0.0.0*
   - symlink *libmy.so.0 -> libmy.so.0.0.0*
   - symlink *libmy.so** -> libmy.so.0.0.0*

When I call *ldconfig* with the verbose flag manually after *make
install* (cache
is still not updated), it does not seem to detect all of them:

$ ldconfig -v -n /usr/local/lib
/usr/local/lib:
libmy.so.0 -> libmy.so.0.0.0

In my opinion, *ldconfig* option *-n* should *not* imply *-N* or at least
update the cache according to the changes (added, modified and deleted
files).
