Lubuntu22.04+brewのasdfでpythonをインストールできない

私の環境

• Lubuntu 22.04
• asdf v0.14.1 (brewでインストール)

asdfでpythonをインストールできない

asdfでpythonをインストールしようとしたところ、下記のようなエラーになりました。

$ asdf install python 3.11.10

解決方法

下記のコマンドを実行して、pythonをインストールできました。brewの状態によってgccのバージョンは違う可能性があります。

brew install openssl readline sqlite3 xz zlib tcl-tk
export CC=/home/linuxbrew/.linuxbrew/bin/gcc-14
export LDFLAGS="-L$(brew --prefix)/lib"
export CPPFLAGS="-I$(brew --prefix)/include"
export PKG_CONFIG_PATH="$(brew --prefix)/lib/pkgconfig"
asdf install python 3.11.10

以下は、インストールコマンドの結果です。なんか色々メッセージが出てますが、インストールは成功しました。
