LuaをFreeDOS用にgccを使ってビルドする
はじめに
そもそもできるかどうかもよくわかっていないので、
とりあえず以下のことができる環境を目指します。
- FreeDOS上でビルドしたLua.exeを実行。
print("hello")と入力してhelloと表示されること。
gccのインストール
ubuntu用のパッケージが提供されているようなので
こちらを利用しインストールします。
バージョンを表示されると以下のように表示されました。

Lua
Lua Ver5.4が最新のようなのでこちらを使用します。
$ wget https://www.lua.org/ftp/lua-5.4.4.tar.gz
とりあえず、こんな感じでいけるのでは？と思ってやった修正
src/linit.cとsrc/Makefileを以下のように修正してみました。

なぜこのようなエラーが出たのか、ということを調べるのは後回しにします。
最初に書いたように今回の目標は以下です。
- FreeDOS上でビルドしたLua.exeを実行。
print("hello")と入力してhelloと表示されること。
なんとなく(??) _getpid_rと_kill_rはprint("hello")には関係なさそうなので 適当に_getpid_rと_kill_r`を自前で実装します。
_getpid_rと_kill_rの実装
以下のように_getpid_rと_kill_rを書きました。
getpid.c
void _getpid_r (void){
return;
}
void _kill_r (void){
return;
}
とりあえずリンクができればよいので
Makefileの修正
再度src/Makefileの修正をします。以下のようにしました。
getpid.oを追加しています。
