RaspberryPi@Raspbian(wheezy)用にQt5beta1をCrossCompileする（その２）

RaspberryPiのRaspbian(wheezy)にて、Qt5beta1をCrossCompileする

Qt5beta1をRaspbian(wheezy)にてCrossCompileした時の覚書です。

前回の続きから

***環境構築Dir構成***

(諸事情でRaspberryPi_Beginners_guide | Qt Wiki | Qt Developer Networkと構築Dir先やDir名は変えています。)

/
|--/opt
|   '--/DeveloperTool
|   |  |--/Qt
|   |  |  '--/qt5-rpi-min/ - Qt5beta1 checkout先
|   |  '-- /RaspberryPi
|   |      '--/Raspbian    - Raspbian (wheezy)のimage置き場
|   '--/toolchain          - RaspberryPi用 Hardfloat CrossCompiler
/mnt
 '--/rpi-rootfs            - RaspberryPi用rootfsマウント先

***cross-compile-toolsの実行***

fixQualifiedLibraryPathsを使用します。
usage:
./cmd target-rootfs path-to-target-toolchain-compiler

$ cd /opt/DeveloperTool/RaspberryPi/Raspbian/cross-compile-tools
$ sudo ./fixQualifiedLibraryPaths /mnt/rpi-rootfs /opt/toolchain/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc

必ずsudoをつけて実行します。(/mnt/rpi-rootfs/内にてlibraryのシンボリックリンクを生成させる為)

となり、あとのqtbaseのCompileにてerrorになります。（→やってしまった人...）

***Qt5のqtbaseチェックアウト***

今回は、qt5 in Qt - Qt by Nokiaから一気にQt5のリポジトリから
取得するのではなく、１つずつモジュールをmakeする事にし、最近ベータ版がリリースされたので、
v5.0.0-beta1のtagにてbuildを進めて行きます。
まずは、qtbaseをチェックアウトしてmakeしていく事にします。
qtbaseをgitから取得

$ mkdir -p /opt/DeveloperTool/Qt/qt5-rpi-min  /* Dir作成 */
$ cd /opt/DeveloperTool/Qt/qt5-rpi-min        /* Dir移動 */
$ git clone git://gitorious.org/qt/qtbase.git
$ cd ./qtbase/
$ git tag                                     /* tagを調べます */
qt-v5.0.0-alpha1
v5.0.0-beta1
/* v5.0.0-beta1 のタグでbranchを作ります */
$ git checkout -b branch-v5.0.0-beta1 v5.0.0-beta1 
Switched to a new branch 'branch-v5.0.0-beta1'
$ git branch                                 /* branchの確認 */
* branch-v5.0.0-beta1
  master

configureの実行

./configure -no-pch -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/opt/toolchain/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rpi-rootfs -opensource -confirm-license -optimized-qmake -reduce-relocations -reduce-exports -release -make libs -prefix /usr/local/qt5rpi 2>&1 | tee ../qtbase_configure.log

→ ./fixQualifiedLibraryPathsが、sudoをつけずに実行した等により正常に実行されなかった場合にでる。

• ハマりどころ２

cc1: fatal error: .pch/release-shared/QtGui: No such file or directory
or
cc1: fatal error: .pch/release-shared/QtGui: そのようなファイルやディレクトリがありません。

→ ここのTroubleshootingにあるように、configureにて“-no-pch”をつけなかった場合にでる。
installの実行
わたしの場合には、configureの-prefixにて、”/usr/local/qt5rpi”と設定しているため
/usr/local/qt5rpiにinstallされました。

$ sudo make install 2>&1 | tee ../qtbase_make_install_.log

つっ疲れた...、次回にてQt5の残りのモジュールについて記載をしていきます。
