Ubuntu 20.04にqtbindings
Post date: 2020/04/28 23:44:00
【問題】
Ubuntu 20.04では、Qt4がサポートされない。Ubuntu 20.04 その1 - Qt 4とQt 4依存アプリを削除する ... - kledgeb
libqt5core5aと、libqtcore4がconflictする。Bug#950614: libqt5core5a conflicts with libqtcore4
【やったこと】
そこで、https://www.ubuntuupdates.org/ から必要なqt4のdebをダウンロードして、依存パッケージをインストールしながらdpkg -iした。Chefのrecipeの関係部分を参考資料にする。

Do you want to continue? [Y/n]
Yで続けると、/lib/x86_64-linux-gnu/libQtCore.so.4など、qt4のライブラリがすべて削除されてします。
【Qt5をインストールしたあとでも、qtbindingsを使えるようにするには】
削除されるライブラリを一箇所（例えば/tmp/qt4lib にコピーし)、
export LD_LIBRARY_PATH=/tmp/qt4lib すればよい。

このあとqtbindingsをインストール
Ubuntu 18.04にQt4をソースからインストールするための覚書
上記のように、Ubuntu 20.04にすでにQt5がインストールされている場合、qt4およびqtbindingsをインストールすることはできない。
そこで、昔やっていたようにQt4をソースからインストールすることを試みたが、まず以下のエラー：
Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /usr/local/src/qt-everywhere-opensource-src-4.8.7/mkspecs/linux-g++.
これは、prerequisitesを守ってないからで、以下で解決：
apt install libfontconfig1-dev libfreetype6-dev libx11-dev libxcursor-dev libxext-dev libxfixes-dev libxft-dev libxi-dev libxrandr-dev libxrender-dev
しかし、これだけでは不十分でmakeの途中でエラーになる。
Installation of Qt 4.8.7 in Ubuntu 18.04.1 LTS によれば、gcc、g++のバージョンを下げ、いろいろやらなくてはならない。
