Full Text Bug Listing

Updating net-snmp on my x86 box has emerge bombing on compile with a 'no right
operand error'.

Reproducible: Always

Steps to Reproduce:
1.emerge -u net-snmp
2. emerge fails.
3.

Actual Results:  
ucd-snmp/disk.c:233:36: error: operator '||' has no right operand
ucd-snmp/disk.c:300:36: error: operator '||' has no right operand

This is the output I get when updating.

Expected Results:  
net-snmp should compile fine.

Thank you for report. I localized this problem and it occurs to be bug in
autoconf-2.61 which had broken AC_FUNC_GETMNTENT macros. Fortunately this bug
is fixed in autoconf 2.62. I'll call maintainers for autoconf-2.62
stabilization. Also I've added dependency >=autoconf-2.62 for this issue in
net-snmp-5.4.1.1. 

Fixed in net-snmp-5.4.1.1.

Well, I was going to test this on my system to see if it's fixed (I'm sure it
is, but want to double check and I get this:

Calculating dependencies -
!!! Multiple versions within a single package slot have been
!!! pulled into the dependency graph:

sys-devel/autoconf:2.5

  ('installed', '/', 'sys-devel/autoconf-2.62', 'nomerge') pulled in by
    ('ebuild', '/', 'net-analyzer/net-snmp-5.4.1.1', 'merge')

  ('ebuild', '/', 'sys-devel/autoconf-2.61-r1', 'merge') pulled in by
    ('ebuild', '/', 'net-analyzer/net-snmp-5.4.1.1', 'merge')



What does that mean?

Zmedico, could you help us here? I've added >=autoconf-2.62 dependency to
net-snmp, and autotools.eclass pulls in >=autoconf-2.61 dependency.  Now when I
have autoconf-2.62 masked I receive different error with the same portage
version:

camobap ~ # emerge -va net-snmp

These are the packages that would be merged, in order:

Calculating dependencies |
!!! All ebuilds that could satisfy ">=sys-devel/autoconf-2.62" have been
masked.
!!! One of the following masked packages is required to complete your request:
- sys-devel/autoconf-9999 (masked by: missing keyword)
- sys-devel/autoconf-2.62 (masked by: ~x86 keyword)

For more information, see MASKED PACKAGES section in the emerge man page or
refer to the Gentoo Handbook.
(dependency required by "net-analyzer/net-snmp-5.4.1.1" [ebuild])

Why do we have different error messages? What could affect this? The only
differences I see are python versions. I have 2.5.2 installed, while Mark has
2.3 and 2.4...

Mark, in any case you should unmask autoconf-2.62, but also mask it after
installation as it has some known regressions at the moment, that why it is and
stay unstable for some time.

This is a case of bug 1343 that's only triggered when you have autoconf-2.62
both installed and masked at the same time. People won't see something like
this unless they have a masked package installed. The correct solution (until
1343 is solved automatically) is to either unmask autoconf-2.62 or else mask it
and downgrade.

The latest autoconf update seems to have fixed the dependency problem as well
as the problem compiling net-snmp.  Great work guys!
