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。
