[gentoo-user] where is libnetsnmp-devel? (needed for hplip)

[Allan Gottlieb]

Which package contains libnetsnmp-devel?

Apparently this is needed for hplip to work correctly with network
printers/scanners/etc.

(I can use the cups interface to print to my network hp-7310, but
hp-setup won't work and I am unable to scan with xsane.  hp-check
asserts that libnetsnmp-devel is a required dependency.)

thanks,
allan

Probably that one, but that's just a guess.

Gentoo doesn't separate packages into -devel versions -- you get all the 
development stuff as part of the base package (since it's usually required to 
compile, as Gentoo does, pacakges that depend on it).

There isn't a "libnetsnmp" package in gentoo, nor a "netsnmp" package in any 
of the *-libs categories.  Naming something "netsnmp" seems a bit redundant 
to me anyway, I'm fairly sure the "N" of "sNmp" stands for "network", so I 
just searched for snmp.  14 hits.  1 is in a *-libs category, but the short 
description says it's specifically for KDE, not what you are looking for I 
think.  1 (other) has "lib" in the name of the package, but it's specifically 
for ruby, again, I was fairly sure that wasn't what you were looking for.  
Also, other distros generally but ruby in the package name of ruby libraries.  
Down to 12 packages.

I threw out packages in dev-perl and perl-python, again, because of other 
distros naming practices.  1 package was in sec-policy which is definitely 
not the place for a lib.  1 package was a plugin for something else, so I 
decided that was also probably not what you want.  Down to 4 packages.

At that point, I decided the most likely package was net-snmp because of the 
name.  bsnmp says it's a library (whereas net-snmp doesn't) so that would 
probably be a good second choice.  snmpmon (a "tool") and snmptt could also 
ship that library, but that's probably a stretch.

Thanks; you are right.  I eventually found it too.  I now see where I
got into trouble.  I didn't set the snmp use flag and hence hplip
didn't bring in net-analyzer/net-snmp.

Is this a bug?  That is, should hplip unconditionally depend on
net-snmp?  hplip includes hp-check, which complained that I needed
libnetsnmp-devel.

I still have not been able to install my network-attached hp officejet
7310 using hp-setup (it install fine via cups).  The trouble is that
scanning doesn't work and various network posts suggest that
installing via hp-setup is needed for most of the hp tool and for full
functionality of the device.

When/if I (with help from the hplip list) resolve my scanning problem,
I will check if net-snmp is really needed.  If so, I am inclined to
file a bug.

I do not think that this is a bug.  If you need information from networked 
printers, e.g. amount of ink left in the cartridge, or what not, then you 
enable the snmp flag and all 4.9M of net-analyzer/net-snmp and 5.9M of its 
dependencies will be downloaded and installed.

Now, hplip-check is somewhat drastic in its remarks:
==========================================
Checking for dependency libnetsnmp-devel - SNMP networking library development 
files...
error: Not found!
error: This is a REQUIRED dependency. Please make sure that this dependency is 
installed before installing or running HPLIP.
==========================================

Does this mean that ALL flags must be enabled for hplip to function properly?  
Hmm, not sure on this one.

Sure, but since your device is networked and you want the full functionality 
this will definitely require the snmp flag AND the scanner flag.

Hope this helps.

Indeed the comments on this group and the hplip list have been quite
helpful.

The snmp use flag is required for a network printer (the wiki had this
but I somehow missed it).

The only problem on the gentoo end is that the ppd files are not put
where hp-setup wants them.

* For the printer not so bad, since hp-setup offers a manual
  specification ability.

* For the fax, no manual specification is offer (I commented on this
  to the hplip list) so adding a symlink is necessary

Thanks for your help.  At this point I have printing (always did, but
now the printer is using hplip) and scanning, the latter was the goal
of the project.  The fax is recognized by hp-setup, but a complaint is
given and I am not a heavy fax user so I am please with the output.
I am following up the fax issue on the hplip list.

Question:  Do you think the fact that the ppd files are not put in the
right place for hplip is a bug I should file?

thanks,
allan

I've noticed this too and it's rather annoying.

Would you perhaps write a wiki article once you've squared all the circles?

Yes, I would think so.  Ideally, the ebuild should cater for 
copying/symlinking appropriate files, or at least popping up a message at 
emerge time to tell you to do so manually.

Although I have emerged hplip I am not using it.  I print through cups using 
hpjis.  Is there a benefit to using hplip and its tools?

Sure.  Perhaps an update to the one that is there.

Right.

I believe hplip gives access to all the features, e.g., ink level, but
I haven't tried anything like that.  The reason I went into this
exercise was to get scanning and that was successful.  It is possible
that I will get computer control of faxing as well (the main question
is how much effort I would be willing to put in considering that I
don't fax much at all).
