I am trying to install ruby-odbc on Windows XP and am stuck at the
first command.  When I run ruby extconf.rb, I get the following:

C:\lib\ruby-odbc-0.996>ruby extconf.rb
checking for sql.h... yes
checking for sqlext.h... yes
checking for SQLTCHAR... yes
checking for odbcinst.h... yes
checking for SQLAllocConnect() in -lodbc32... no
Can not locate odbc libraries

I copied the odbc_utf8.so and odbc.so to the following location
.../ruby/1.8/i386-msvcrt according to the documentation.

I'm a bit of a newb, so any help would be appreciated.

Thanks in advance,
eric
