Settling OpenCV2.1 on Ubuntu

My Linux workstation has been upgraded all the way from Ubuntu 7.10 to 10.04, never missing a major release. And this possibly has created left garbages behind and hence caused itches. For example, I have never succeeded compiling and installing OpenCV on.  (What a pity and shame for a vision researcher! 🙂 )

Yesterday after a normal maintenance update, the box wouldn’t run smoothly. After desperately trying to  solve the problem for several times, without success, I turned to decide to make it a reincarnation. And …. 6 hours later, after the lengthy backup process, I installed the latest version of Ubuntu (10.04, Lucid) and was rewarded with another blessing: OpenCV2.1 now settled on it without any problem. Cheers! And as well thanks to this guy for his helpful blog.

SSH timeout problem in Ubuntu 10.04

Upgrading from previous versions of Ubuntu may result in the problem. Some simple research suggests it may be because SSH client confuses IPv6 with IPv4. So  the workaround is to force the IPv4 search only:

ssh -C  -4 idmsj@xxx.xx.xx.xxx

Btw, my blog received 1,000 hits by yesterday! 🙂
