However, I am still getting the exact same error. I believe it has something to do with the ruby source. You said to include a folder that would default to Dev\language\ruby\src etc., but no such folder exists on my system. I'm assuming that this source was what you should use to build ruby. I did not build ruby myself, I downloaded a pre-built ruby for windows that has no source in it. So, I downloaded the ruby source from the website, which made a folder called C:\ruby-1.8.3, which had several .c files in it. So instead of the Dev\language thing I just replaced that with C:\ruby-1.8.3. Apparently that was not the correct thing to do. Otherwise, I did everything else exactly as you said. Is there something that I'm missing?

I did a write up that should hopefully guide you through the process. http://www.koontzfamily.org/david/blog/?p=230 HTH, David Koontz >Hello, >I would very much like to be able to compile a C extension for Ruby using MSVC, but I am coming across many problems. First of all, I am using extconf.rb with nothing but a create_makefile() statement. When it creates the makefile and I try to run it, it complains about not being able to find header files and libraries. So I went into the makefile and manually changed things so that it would include everything that it asked for. However, I am now getting an error that says: > >c_lib-i386-mswin32.def : error LNK2001: unresolved external symbol Init_c_lib >c_lib.lib : fatal error LNK1120: 1 unresolved externals >LINK : fatal error LNK1141: failure during build of exports file >NMAKE : fatal error U1077: 'C:\WINDOWS\system32\cmd.exe' : return code '0x2' >Stop. > >"c_lib" is the name of the extension and .c file. I believe this may have something to do with it asking me to link a library called msvcrt.lib, which was located in a directed called amd64 or ia64. I'm not sure what these two things mean, but I know that they do not work with my system. I believe the one that works for me is x86. However, those two directories were the only one that had msvcrt.lib. > > > > --------------------------------- Yahoo!
