Hi,

I just installed mmrnmhrm. When selecting New Dee Project and clicking Next nothing happens. In Error Log I have:

eclipse.buildId=M20100211-1343
java.version=1.6.0_18
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=pl_PL
Command-line arguments: -os linux -ws gtk -arch x86


Error

Mmrnmhrm 0.3.0 does not run in Eclipse 3.6 (Helios). That's because Helios has DLTK 2.0, which is not compatible. Note this quote from the UserGuide: "A few dependencies should show up, namely DLTK which should be version 1.0 or compatible." Unfortunately the Mmrnmhrm dependencies config allows 2.0 as a valid dependency (it should not).

Install Mmrnmhrm with Eclipse 3.5 (Ganymede) + DLTK 1.0.
Or alternatively, uninstall Mmrnmhrm 0.3 and try DDT 0.4.0 from a development build: http://svn.dsource.org/projects/descent/downloads/ddt-site-developmentbuilds/
This has better D2 support but is buggier. It's not an official release yet, please be patient (I got sidetracked, and its gonna take me longer to properly release DDT 0.4)
