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.

Hey Eric, I just went through all this myself. I did a write up that should hopefully guide you through the process. http://www.koontzfamily.org/david/blog/?p=230

It is the function what *you* have to write to initialize the
extension.

I can think of some mean programmer as protagonist based horror stories

Continuing this OT thread, I am currently "reading" (actually, I
listen to audiobooks as I commute) Snow Crash by Neal Stephenson. It
is a very, very good and the protagonist is a hacker named "Hiro
Protagonist". Its sci-fi, not horror, but its one of the best books
I've read in a while.

And for one last addition to the OT'ness. If you like Snow Crash make sure
to check out a couple of his other books, especially Diamond Age and
Cryptonomicon.
