Just a short blog post: after merging OpenOffice.org on a Hardened Gentoo machine today, I was unable to boot OpenOffice.org Writer (or any of the other OOo programs). While the solution isn’t all that pretty, it is rather simple.
The problem has to do with OpenOffice.org throwing out the following error when trying to boot in Hardened Gentoo:
terminate called after throwing an instance of ‘std::bad_alloc’
what(): std::bad_alloc
Turns out this has to do with the way OpenOffice.org tries to work against the mprotect restrictions. You can lift those restrictions by using paxctl (emerge -av paxctl) in the following way:
# check for current PaX settings:
paxctl -v /usr/lib/openoffice/program/soffice.bin
# disable mprotect:
paxctl -m /usr/lib/openoffice/program/soffice.bin
Now OOo should finally launch. This enables you to write a polite letter to the OOo team asking them to allow us to run OOo with mprotect.

Lately, my Adobe Flash on Gentoo amd64 complained about being blocked by the Adobe Flash 10.0 license and since yesterday the 10.1 one. Blocked by a license? Had never seen that before…

After attending the keysigning party at FOSDEM 2010, I came home with a large list of PGP/GnuPG keys I needed to sign. At the conference, there was a brief mention of using caff to make this task easier and soon enough, the first emails sent using caff came rolling in. Problem was… I had no experience whatsoever using caff, and the documentation was rather brief. I did manage to figure it all out though.

While equipping my fresh Gentoo server with NTP capabilities I was wondering why after a couple of minutes after starting ntpd, ntpq -p (or ntpq -c peers) was shouting “ntpq: read: Connection refused” at me… What is going on?

Had a rather unpleasant bug for about a week and could not figure out what the exact issue was. Problem: when booting KDE, the KSplash screen would load and when the KDE gears appeared, the whole system would lock up. As in freeze, not able to switch to different terminal, nothing.

After Mozilla Firefox 3.5(.1) was finally unmasked in Portage, I upgraded from 3.0. Unfortunately, after the update, Firefox would not start anymore and when started from a terminal, it would leave me with a cryptic “Couldn’t load XPCOM.”.

Less than a week after my previous post on blockers caused by poppler, perl-core/Compress-Zlib and perl-core/IO-Compress-Zlib pop up as blockers in my emerge -uDN world.

When updating world, as we should all do every now and then, yesterday I was confronted with a number of different blocks relating to poppler. Usually I find it easiest to unmerge a blocking package by hand and see if the dependency conflict resolves itself. This time that wasn’t quite what I needed.

Well, that was what I wanted. I know, Conficker was hot months ago. But hey, I’m not often around Windows machines and I thought that while I was, I might just as well scan my parents’s network.
