Qtのビルド

はじめに

Qt5.5のオフィシャルバイナリではVS2010 32bit、VS2013 32bit、64bitが提供されていてその他のバージョンのバイナリが提供されていない。(Qt5.6からはVS2015の32bit、64bitのバイナリが提供されるようだが、VS2010の提供が外れるようだ。)OpenCVにQtを組み込もうとしたときにオフィシャルバイナリが準備されていない環境でQtを組み込みたい場合はソースからビルドする必要がある。

Qtのソースをダウンロード

ネットで検索するとソースの取得をgitを使って行う方法の記載が多いですが、ダウンロードページにソースファイルのリンクがあって、これを使うとparlのスクリプトを実行する手間もいりません。

Download Qt Open Sourceページを開く。

ページが下に広がるのでスクロールしページ中程にあるSource packages & Other releasesが表示されるまでスクロールする。

For Windows users as a single zip file (542 MB) のinfoリンクをクリック

Qt Downloadsページが開く

Qtダウンロードページ

Download fileをクリックするとファイルのダウンロードが始まる。

ダウンロードが完了するとqt-everywhere-opensource-src-x.x.x.zip(x.x.xはバージョンナンバー今回は5.5.1)というファイルができる。

ソースを展開

インストールカレントフォルダーの直下に「qt」というフォルダを作成する。

qtフォルダ内にダウンロードしたzipファイルを展開する。「qt\qt-everywhere-opensource-src-x.x.x」にソースファイルが展開される。

Qtのビルド

ビルドの手順はconfigureで環境に合わせた中間ビルドファイルを作成した後nmake→nmake installと進めていく。
nmakeコマンドで実行すると3時間程度ビルドに時間が掛かるので、
QtCreatorに付属しているjomコマンドを使用する方がよいです。1程度でビルドが完了する。

jomコマンドを使用する場合はあらかじめQtCreatorをインストールしておく必要がある。QtCreatorをデフォルトインストールした場合、Jom.exeのある場所はC:\Qt\Tools\QtCreator\binである。

configureは展開したソースファイルが格納されているフォルダ直下にあるconfigure.batを使用する。

ビルドするVisual StudioのNative Toolsコマンド プロンプトで以下のコマンドを実行する。64ビット版をビルドする場合はx64 Native Tools コマンド プロンプト、32ビット版をビルドする場合はx86 Native Tools コマンド プロンプトを使用する。(Native Tools コマンド プロンプトの名称はVisual Studioのバージョンによって多少異なる。)

%OUTPUT_DIR%には最終的にライブラリバイナリーが格納されるフォルダを指定する。

Configure -developer-build -confirm-license -opensource -nomake examples -nomake tests -opengl desktop -no-warnings-are-errors -prefix "%OUTPUT_DIR%"

Visual Studio 2013(たぶん2015も)は-no-warnings-are-errorsを指定しておかないとnmakeしたときにエラーがでる。

-platformオプションは環境変数QMAKESPECで宣言しておけばオプションで指定する必要はない。

qt_build.batとして以下のような内容をバッチファイルとしてカレントフォルダに登録していると簡単にビルドができる。

引数でVisual Studioのバージョンとプラットフォームを指定する。Visual Studio2013 でx64のビルドをしたい場合はコマンドプロンプトで下記のように入力して実行する。

qt_build 2013 64

Qtのバージョンは環境変数QTVERで指定する。

set VERNUM=%1
set PLATFORM=%2
set QTVER=5.5.1
set CURRENT_DIR=%~dp0
set JOMDIR=C:\Qt\Tools\QtCreator\bin
set BUILD_DIR=qt\build\%QTVER%-msvc%VERNUM%-x%PLATFORM%-opengl
set OUTPUT_DIR=%CURRENT_DIR%qt\DLL\\%QTVER%-msvc%VERNUM%-x%PLATFORM%-opengl
set PATH=%JOMDIR%;%CURRENT_DIR%%BUILD_DIR%\qtbase\bin;%PATH%
set QMAKESPEC=win32-msvc%VERNUM%
 
mkdir %BUILD_DIR%
cd %BUILD_DIR%
 
call ..\..\qt-everywhere-opensource-src-%VERNUM%\configure.bat -developer-build -confirm-license -opensource -nomake examples -nomake tests -opengl desktop -no-warnings-are-errors -prefix "%OUTPUT_DIR%"
 
call jom
 
call jom install
 
cd ..\..\..\

ビルドの途中でpythonを使用するのであらかじめpythonをPCにインストールしておく必要がある。
