[Pkg-hpijs-devel] Bug#454117: hpijs: depends on hplip

[Mark Purcell]

Hi Josselin,

I'm back on deck now and working my way through the extant hplip/ hpijs bugs.

hpijs does depend on libraries from hplip:

# ldd /usr/bin/hpijs | grep libhp
        libhpip.so.0 => /usr/lib/libhpip.so.0 (0x0ffb4000)
        libhpmud.so.0 => /usr/lib/libhpmud.so.0 (0x0feaf000)

# dlocate libhp
hplip: /usr/lib/libhpip.so.0.0.1
hplip: /usr/lib/libhpmud.so.0.0.2
hplip: /usr/lib/libhpmud.so.0
hplip: /usr/lib/libhpip.so.0

So the dependency is correct and it would be the wrong thing to change the 
Depends into anything less at this stage. In fact hpijs does not run without 
those libs ;-)

You can try if you like with `dpkg --force-depends --remove hplip` and see 
what happens when you run hpijs:

# hpijs
hpijs: error while loading shared libraries: libhpip.so.0: cannot open shared 
object file: No such file or directory

The daemons have now been removed from hplip and there is a separate hplip-gui 
package, so hopefully these issues are addressed.

As shown above it does need the libraries.

We could split the libs into another libhplip package, I suppose.  However, I 
have had issues in the past with another package that provided similar 
internal libaries.  The issue was version skew between the packages and the 
psuedo-library package. After all it isn't a real library package.

Happy to discuss the issue some more though.
