Eike informed me that the previous binary I posted was not deployable with a regular OO.o build due to binary incompatibility with gcc (or g++ rather). I compiled my last binary using gcc 4.0, and gcc 4.0 apparently introduces compatibility symbols GLIBCXX_3.4.4 and GLIBCXX_3.4.6 which are not understood by a binary built using gcc 3.4.1 (such as a regular OO.o build). See Eike’s this blog entry for more details. So, I downloaded gcc 3.4.1, and rebuilt my solver package. I ran objdump -T scsolver.uno.so to make sure there were no GLIBCXX_3.4.x symbols (there weren’t).

Feature: Slim Down and Speed Up Linux

Click to view While Linux is pretty efficient with a computer's resources out of the box, there are still ways you can make it run leaner and meaner on your desktop. Using a little bit of know-how, a willingness to run a few terminal commands, and a mind for efficiency, you can get every last bit of power from your Linux box, or get more life from an older system. Read on for a roundup of ways to slim down and speed up Linux that any level of user can implement. One quick note: Many of these tweaks require altering system files, disabling processes or otherwise changing how your system runs.
