** Description changed:

- Context : I haven't this problem in Lucid Lync (10.04), on i686 and x64,
- this appear in Precise (12.04) in i686 and x64
+ Impact: the extension providing the fuse bindings is not linked against
+ libfuse making it unusable
+ 
+ Fix: this is caused by an incorrect linking order and ld --as-needed,
+ fix is simply reordering the commandline correctly
+ 
+ TEST CASE:
+ ldd /usr/lib/perl5/auto/Fuse/Fuse.so
+ 
+ should show links against libfuse
+ 
+ ldd -r ldd /usr/lib/perl5/auto/Fuse/Fuse.so should only show undefined
+ symbols provided by perl (Perl_, PL_, perl_) and not libfuse.
+ 
+ Regression potential:
+ low, only command line reordering, current package unusable
+ 
+ 
+ original report:

  To correct this  In the source package, I've modified the Makefile.PL line 47 
from
-         'OBJECT'                => "$obj Fuse.o -lpthread", # link all the C 
files too
+         'OBJECT'                => "$obj Fuse.o -lpthread", # link all the C 
files too
  to
-         'OBJECT'                => "Fuse.o $obj -lpthread", # link all the C 
files too
+         'OBJECT'                => "Fuse.o $obj -lpthread", # link all the C 
files too
  
  And now (after reinstall my own package) its fine : my fuse/perl application 
is working and ldd give my back what I hope :
