Siyuan- You should start by making sure you can run Larceny at the command line with your setup. The way you have described it, I suspect you do not have the LARCENY_ROOT set correctly in your copy of the script.
Only after confirming that you can run Larceny in the Terminal.app should you attempt to configure it with Eclipse+Schemeway. The installation documentation in doc/HOWTO-INSTALL [1] describes how to set the LARCENY_ROOT. In particular, the LARCENY_ROOT needs to point to the directory containing the full Larceny distribution (which holds the various .heap files as well as library files that are loaded on demand). In my case, I have a copy of the larceny distribution here: /usr/local/lib/larceny/larceny-0.97-bin-native-ia32-macosx/ I could run the larceny script directly from that directory (the script in its pristine state will assume that it is invoked from the LARCENY_ROOT), but since that directory is not on my PATH, I instead usually run a different copy of the script that I have installed elsewhere, such as my ~/bin/ directory. In your case, you can put a copy of the script in /usr/local/bin, as it sounds like you have done, but you need to set its LARCENY_ROOT so that it points to a full distribution of larceny (which means that "/usr/local/bin" is not an appropriate LARCENY_ROOT, and neither is "/usr/local/lib" probably). The different copy of the script needs to be explicitly told what the LARCENY_ROOT is, e.g. via a line at the top like: LARCENY_ROOT=/usr/local/lib/larceny/larceny-0.97-bin-native-ia32-macosx (The script already includes a line much like this, commented out, within the first ten lines. So just make a copy of the script and edit that line to point to the correct directory, depending on what you have named that directory.) Once you have done this, you should be able to run Larceny like so in Terminal.app: % /usr/local/bin/larceny Larceny v0.97 "Funny in the Head" (Aug 19 2009 04:24:46, precise:Posix:unified) larceny.heap, built on Wed Aug 19 04:26:48 EDT 2009 > (exit) % ---- [The remaining text is probably mostly of interest to people who want to know more about the schemeway plugin itself; I suspect Siyuan does not need the information below.] Once you are able to run Larceny itself, then you just need to install and configure the schemeway plugin. For me, after installing the schemeway plugin to the Eclipse dropins [2], I was able to just point schemeway to the absolute path for same larceny script that I would run from the command line in Terminal.app. I didn't bother changing the working directory setting; Larceny should be able to run regardless of working directory (as long as the LARCENY_ROOT has been set by the environment or startup script). The hardest part for me was figuring out how to use Schemeway itself to test my setup [3]. Once I did all that, the basics like loading a file and evaluating en expression [4] seemed to work. Cheers, -Felix [1] The HOWTO-INSTALL is included in the Larceny distribution; the current version can be seen here: https://trac.ccs.neu.edu/trac/larceny/browser/trunk/larceny_src/doc/HOWTO-INSTALL [2] http://stackoverflow.com/questions/926594/installing-a-plain-plugin-jar-in-eclipse-3-5 [3] (I am not an Eclipse expert.) I did find the notes here helpful: http://esaliya.blogspot.fr/2009/09/scheme-way-eclipse-plug-in.html In particular, the instruction: "Window --> Open Perspective --> Other --> Scheme" was crucial for me. [4] To evaluate an expression in your buffer on its own, see "Eval" in the right-mouse-click menu (or just type Ctrl-Enter).
