●【世界最小】FPGAに 32bitマイコン Zylin CPUの ZPUを実装して gccで開発する方法【gcc】
Zylin ZPU、Worlds Smallest 32 bit CPU with GCC toolchain
これも Papilio FPGA用の GitHubの内容を ALINX AX309で動く様に変更します。

ビルド環境
・Windows 10 WSL Windows Subsystem for Linux
・Raspberry Pi OS Lite Release date: April 4th 2022 32-bit
● Windows 10 WSL Windows Subsystem for Linux
Linux環境としてラズパイも便利だけど WSLも便利だわさ！
Microsoft Windows 10 Pro 21H2 Version 10.0.19044
ver
rem Microsoft Windows [Version 10.0.19044]
wsl --status
# Linux 用 Windows サブシステムの最終更新日: 2022/04/24
# カーネル バージョン: 5.10.102.1
wsl --unregister Debian
wsl --install -d Debian
● Windows WSLで sshd（SSH接続のサービス）を有効にして SFTPで接続できるようにする
Windows側のクライアントアプリは WinSCPが簡単でオススメ。
WinSCPとは
sudo apt install -y openssh-server
sudo service ssh restart
# [ ok ] Restarting OpenBSD Secure Shell server: sshd.

● Zylin CPU ZPU zpugcc toolchain Build Message
----------------------------------------------------------------------
Libraries have been installed in:
/home/pi/zpugcc/toolchain/gccbuild/../install/zpu-elf/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

make[2]: Leaving directory '/home/pi/zpugcc/toolchain/gccbuild/zpu-elf/libgloss/zpu'
●Solution
toolchain/gcc/libgloss/zpu/Makefile.inの name=`$$objdump -f $(CRT0) | sed '/^$$/d'`;の末尾に \を追加する。
fix Makefile.in
nano ../gcc/libgloss/zpu/Makefile.in

●Solution
Linux版の実行ファイルのパスを PATHに追加する
export PATH=`pwd`/install/bin:$PATH
・ configure: error: installation or configuration problem: C compiler cannot create executables.

checking for working autoconf... missing

●Solution
？？？
解決方法が不明
●その他、Linux環境での裏技
・ bashスクリプトには set -euを設定すると良い
理由：
-e 途中でエラーが発生した場合に中断してくれる設定
-u 変数が未設定の状態だとエラーにしてくれる
#!/bin/bash
# set --help
# set -eu
# -e Exit immediately if a command exits with a non-zero status.
# -u Treat unset variables as an error when substituting.
・ configureが失敗する時の緊急避難の設定方法
configureに --disable-werror を追加する。
make -kで -kオプションを付ける。
Installing GCC: Configuration
理由：
--disable-werror warningをエラー扱いしない
-k, --keep-going 途中でエラーが有っても無視して続行する
configure --disable-werror
Do not Make all warnings into errors
make -k
-k, --keep-going Keep going when some targets can't be made.
