The chainlink site is still available:
http://chainlink.sourceforge.net/, but the source and binary files have been removed. I may consider putting them back, but chainlink1 will no longer be supported nor developed. Please try the updated svn link for chainlink2 (see group page
http://groups.google.com/group/chainlink) -- for various reasons, I removed the links to the program (I don't want to explain right now). Please let me know if you have any problems with compilation of chainlink2.
There is one thing you need to be aware of when compiling chainlink2... Follow these steps for first compilation:
1. cd src/codegenerator
2. qmake/make
3. cd ..
4. qmake/make
