It's not clear to me which version you are using? Depending on the version, It is referred to in the URL you linked...
I'll just cut to the chase use 0.4 and julia_config.jl as described in the doc, create a Makefile just cut-and-paste the example, and augment with your source. All but one of your errors is a result of the wrong compile/link flags. The last error is that main() is either not being compiled or linked, that's just straight-up C programming, and has nothing to do with Julia. As far as eclipse goes, I'm confident it's possible, I can't imagine eclipse not supporting compilation using Makefiles, but even if it doesn't you can still automate things, but just get something working first and you can embellish later. TL;DR 0.4, julia_config, cut-paste Makefile, add your source, done
