New Access Method

Hello,<br /><br />I am trying to create a new index which is multidimensional (based on R-Tree) which can be used for
datawarehosuing. I have read the Developers' manual about adding new indexes, and now I want to start coding the new
index.<br /><br />My first step is to create the skeleton files, but I cannot compile Postgres now because of errors.
Thisis what I have done:<br /> - Create a header file in /src/includes/<br /> - Create a folder in /backend/access/ for
thenew index. <br /> - Created a new C file in the above folder <br /> - Copied a Makefile from the other access
methods,and changed the references to point to my C file <br /> - Edited the /backed/access Makefile to include my new
folder<br/><br />I am using Eclipse on WindowsXP. Any pointers about what have I done wrong or anything I missed?<br
/><br/>Thanks,<br />Alan<br />
