"test_scheme_embed.c":  [output to ".\test_scheme_embed.obj"]   followed by: "C:\Program Files\MzScheme\mzc.exe" --ld test_scheme_embed.exe test_scheme_embed.obj   yielding: mzc v371 [3m], Copyright (c) 2004-2007 PLT Scheme Inc. mzc: not a MzScheme extension filename (doesn't end with .dll): test_scheme_embed.exe   I imagine there's something obvious I'm missing, but I haven't discovered what yet.  Any advice appreciated.   Thank you, Matthew P. <HR id=stopSpelling> > Date: Fri, 30 Nov 2007 10:32:54 -0700 > From: czhu@cs.utah.edu > To: mvfpadilla@hotmail.com > CC: plt-scheme@list.cs.brown.edu > Subject: Re: [plt-scheme] mzc embedding question > > Matthew Padilla wrote: > > Hello, > > > > I would like to compile a C++ program that embeds MzScheme, similar to > > the example given in the online documentation (see example at end of > > email).
