net-snmp-5.4.1-r3 does not provide hrStorageDescr for mount points. Only memory and swap is visible. net-snmp-5.4.1-r1 compiled in September 6th works. The trouble is that if r1 is recompiled now, it also does not work any more. I have tried to compile it with gcc-4.1.2 as before, but that did not help. I guess there might be something wrong with the headers, otherwise the the old binary package would not work. Any suggestion what to try? Downgrade sys-kernel/linux-headers or something similar? There are few similar reports on net-snmp-user mailing list without a solution. emerge --info: Portage 2.1.4.1 (default-linux/amd64/2007.0, gcc-4.2.2, glibc-2.7-r1, 2.6.20-gentoo-r6 x86_64)

The problem is the configure script sees the existence of /etc/filesystems and tries to use it in preference to /etc/fstab, mistakenly assuming that /etc/filesystems contains a list of mounted filesystems. Moving /etc/filesystems aside and emerging net-snmp resolves the problem. A patch to 'configure' should be added to the ebuild that does not prefer /etc/filesystems over /etc/fstab. http://forums.gentoo.org/viewtopic-p-5099291.html?sid=5e6a83d8f11365127d68e6c04390200e#5099291
I don't think /etc/fstab is correct solution. configure checks for /etc/mnttab /etc/mtab /etc/filesystems. On linux system /etc/mtab should be used. Do you have this file, Andrej?
And btw, /etc/mtab could be symlink on /proc/mounts, but check that you /proc is really mounted. Matt, btw, have you reproduced this problem? But I suppose that your hint is correct. Thanks.
Ah yes, it looks like /etc/mtab would be the correct choice as it is automatically generated from /proc/mounts by /etc/init.d/checkroot. I have reproduced the problem and confirmed that my work-around resolves the issue with subsequent builds of net-snmp with/without /etc/filesystems in place.

Then I suppose that bug is INVALID as net-snmp already checks for /etc/mtab existents and the bug itself looks like misconfiguration... If you disagree, please, reopen.
No, the bug is that the configure script finds /etc/filesystems before it looks for /etc/mtab. The ebuild for net-snmp leaves it in a broken state. So this bug is neither resolved or invalid. I don't seem to have the access required to reopen the bug. > Then I suppose that bug is INVALID as net-snmp already checks for /etc/mtab > existents and the bug itself looks like misconfiguration...

I did test the new r4 ebuild with /etc/filesystems removed and /etc/mtab linked to /proc/mounts and it works. Since I do the binary builds in a chroot system before I install them on the cluster, /etc/mtab was empty. net-snmp is the only packages with such problems.
(In reply to comment #6) > No, the bug is that the configure script finds /etc/filesystems before it looks > for /etc/mtab. Um, no. Configure checks for /etc/mtab before: if test "$ac_cv_ETC_MNTTAB" = "unknown"; then for i in /etc/mnttab /etc/mtab /etc/filesystems do if test -f $i; then ac_cv_ETC_MNTTAB="$i" break; fi done (In reply to comment #7) > I did test the new r4 ebuild with /etc/filesystems removed and /etc/mtab linked > to /proc/mounts and it works.

This is misconfiguration of chroot as there are many things which are broken when /proc is not mounted... That's said, next net-snmp release will add ./configure option to set this file: --with-mnttab=/etc/mtab thus it's worth to add it, I think... Reopening until next release.
At the very least, my ebuild from bug #234036 fixes this issue. It may be fixed in earlier versions or revisions, but I haven't tested it on anything else. sky01 ~ # snmpwalk -v2c -c nagios localhost hrStorageDescr HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: Physical memory HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Virtual memory HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: Memory buffers HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: Cached memory HOST-RESOURCES-MIB::hrStorageDescr.8 = STRING: Shared memory HOST-RESOURCES-MIB::hrStorageDescr.10 = STRING: Swap space HOST-RESOURCES-MIB::hrStorageDescr.31 = STRING: / sky01 ~ # emerge -Cp net-snmp >>> These are the packages that would be unmerged: !!!
