次はPython。でも...
続いてPythonを確認します。本家のUbuntuディストリビューションであればPythonのVer. 2系がインストールされていると思います。しかし、WSLでは何がインストールされているのでしょうか。まず確認してみたいと思います。
$ python --version ↵ The program 'python' can be found in the following packages: * python-minimal * python3 Try: sudo apt install
おや？
インストールされていないようです。
全ての開発作業をLinuxで行う場合はPythonが必要なことは理解しています。しかし、今回の環境はWSLです。コンパイル環境を構築しているにすぎません。
そこでPythonは、必要になってからインストールすることにします。
ツールチェインの準備
クロスコンパイルを行う際にはツールチェインというものが必要なのだそうです。
ARMなどの有名なCPUであればビルド済みのツールチェインが提供されていたりするようですが、ESP8266で利用されているCPUのツールチェインは自前でビルドする必要があるようです。

Installing libtool-bin solves this issue.
