H8 3069クロスコンパイル開発環境のセットアップ

Last updated at Posted at 2019-05-25

12ステップで作る組込みOS自作入門をやるために
H8 3069のクロスコンパイル環境を構築した際のメモ.

環境

  • OS
    Arch linux 64bit

試した手順

$ wget http://kozos.jp/books/makeos/download.sh
$ chmod +x download.sh
$ ./download.sh
$ chmod +x build-binutils.sh
$ chmod +x build-gcc.sh
$ ./build-binutils.sh
$ cd binutils-2.19.1
$ sudo make install
$ cd ..
$ ./build-gcc.sh
$ cd gcc-3.4.6
$ wget http://kozos.jp/books/makeos/patch-gcc-3.4.6-x64-h8300.txt
$ patch < patch-gcc-3.4.6-x64-h8300.txt
# パッチ対象が聞かれるので,"gcc/config/h8300/h8300.c"を¥入力
$ make
$ sudo make install

以下で記述しているエラーに対応済み.

引っかかったポイントと解決法

公式サポートページにあるように64bitOSでサポートページの手順をとると,
make install が以下のエラーで止まる.

./libgcc2.c: In function '__muldi3':
./libgcc2.c:542: error: unrecognizable insn:
(insn 234 233 235 2 ./libgcc2.c:533 (set (reg:HI 3 r3)
        (const_int 4294967214 [0xffffffae])) -1 (nil)
    (nil))
./libgcc2.c:542: internal compiler error: in extract_insn, at recog.c:2077
Please submit a full bug report,
with preprocessed source if appropriate.
See  for instructions.

そのため,以下の手順を追加した.

$ wget http://kozos.jp/books/makeos/patch-gcc-3.4.6-x64-h8300.txt
$ patch < patch-gcc-3.4.6-x64-h8300.txt
# パッチ対象が聞かれるので,"gcc/config/h8300/h8300.c"を入力.
$ make
