1#define _PAGE_ Setting up an SH-1 compiler for Windows
2#include "head.t"
3<P>
4by <A href="mailto:edx@codeforce.d2g.com">Felix Arends</A>, 1/8/2002
5<BR>

7<P>
8NOTE: THIS COMPILER DOES NOT YET WORK WITH WINDOWS XP!!!
9
10<P>
11I have spent a long time figuring out how to compile SH1 code in windows (using
12the sh-elf-gcc compiler) and when I finally compiled the first OS for my
13Jukebox I decided to write a little tutorial explaining the setup process.
14
15<H2>
16The GNU-SH Tool Chain for Windows
17</H2>
18<P>
19This is actually all you need to download. It includes the binutils, gcc and
20newlib. The complete GNUSH Tool Chain (currently v0101) is 117MB but for you it
21is enough to download the GNUSH Tool Chain for ELF format (45 MB).
22
23<P>
24The GNUSH website can be found at <a href="http://www.kpit.com/download/downloadgnu.htm">
25http://www.kpit.com/download/downloadgnu.htm</a> (source code is also
26available there) and the direct link to the file you need is <a href="http://www.kpit.com/download/elf.zip">
27http://www.kpit.com/download/elf.zip</a>. It uses the cygwin dll to emulate
28a linux layer but you do not have to care about that.
29
30<H2>
31Setting up&nbsp;the Compiler
32</H2>
33<P>
34Install the GNUSH Tool Chain (nothing you really have to care about during the
35installation process). After that you should add some paths to your PATH system
36environment variable. If you have Windows 95/98/Me you can do that by modifying
37your autoexec.bat:
38
39<P>
40Add the following line to your autoexec.bat:

60Replace the beginning of the paths with the path-name you chose to installt the
61tools in. Reboot.
62
63<P>
64In Windows 2000 it is a bit different. You can find the PATH-environment
65variable if you right-click the "My Computer" icon on your desktop and choose
66"Properties" in the popup-menu. Go to the "Advanced" tab and click
67"Environment-Variables":

74not matter which one you edit)

77To the value the PATH-variable already has, add:

95An "empty" System
96</H2>
97<P>
98First of all, I'll explain what to do to compile an "empty" system. It just
99initializes and calls the <EM>main</EM> function, but does not do anything
100else. You can add some code to the <EM>main</EM> function and simply recompile.
101It is actually like this: You don't have to care about any of those files,
102because you won't have to change much of them (except the main.cpp of
103course!!).

266don't have to copy'n'paste that much :). I have also prepared a package with
267the LCDv2 code Björn wrote (ready to compile with Windows).
