開発環境

製品仕様書 Appendix B にしたがって作成した hdd ブート環境の開発環境を見てみる。

Hellow World

~ # cd /tmp
/mnt/ram/tmp # cat > a.c
main()
{
printf("Why don't you hack KURO-BOX/Pro\n");
}
/mnt/ram/tmp # cc a.c
/mnt/ram/tmp # ./a.out
Why don't you hack KURO-BOX/Pro
/mnt/ram/tmp #

動くやん（笑）

カーネル

いきなりかい。
Appendix C には「現状、カーネルをターゲット上でコンパイルすることはできないので・・・」という記述があるというのに、、、

~ # cd /home/
/home # mkdir kernel
/home # cd kernel
/home/kernel #
/home/kernel # ftp giga.yamasita.jp
ftp: ftp/tcp: unknown service
/home/kernel #

がー。 Windows のファイル共有で、linux-2.6.12_lsp.1.10.3.src.tar.gz をコピーする。

/home/kernel # tar zxvf linux-2.6.12_lsp.1.10.3.src.tar.gz

Appendix C.2 の 2 には解凍して make するだけってかいたるやん。
