ARM40 Ubuntu交叉編譯Qt4.8.7

準備

    主機平台：Ubuntu 16.04 LTS(x64)

    目标平台：ARM40-A5D3

    Qt版本：Qt4.8.7

    tslib github

    ARM-GCC編譯工具鍊：gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi

交叉編譯工具鍊

    下載下傳gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi.tar.xz

    gcc.png

        安裝ARM-GCC編譯工具鍊

$ sudo xz -d gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi.tar.xz

$ ls

$ sudo tar xvf gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi.tar -C /opt/

    編輯.bashrc檔案

$ cd ~

$ vim .bashrc

    在.bashrc的末尾添加下面的文本

        export PATH=$PATH:/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi/bin/

    檢視ARM-GCC版本

$ arm-linux-gnueabi-gcc -v

    Thread model: posix

    gcc version 4.9.4 (Linaro GCC 4.9-2017.01)

安裝tslib

    使用浏覽器下載下傳tslib

    下載下傳tslib

    使用git下載下傳tslib

$ sudo apt-get install git

$ git clone https://github.com/kergoth/tslib.git

    正克隆到 ‘tslib’…

    remote: Counting objects: 5089, done.

    remote: Total 5089 (delta 0), reused 0 (delta 0), pack-reused 5089

    接收對象中: 100% (5089/5089), 2.39 MiB | 429.00 KiB/s, 完成.

    處理 delta 中: 100% (3505/3505), 完成.

    檢查連接配接… 完成。

    編譯tslib

$ sudo apt-get install automake libtool

$ sudo mkdir /opt/tslib

$ cd tslib

$ ./autogen.sh

$ ./configure CC=arm-linux-gnueabi-gcc \

               CXX=arm-linux-gnueabi-g++ \

               --prefix=/opt/tslib \

               --host=arm-linux-gnueabi \

               ac_cv_func_malloc_0_nonnull=yes

$ make&&sudo make install

    編譯報錯

        /home/jonny/tslib/libtool: line 10540: arm-linux-gnueabi-gcc: command not found

        libtool: error: error: relink ‘linear.la’ with the above command before installing it

        Makefile:755: recipe for target ‘install-pluginexecLTLIBRARIES’ failed

        make2: * [install-pluginexecLTLIBRARIES] Error 1

        make2: Leaving directory ‘/home/jonny/tslib/plugins’

        Makefile:1021: recipe for target ‘install-am’ failed

        make1: * [install-am] Error 2

        make1: Leaving directory ‘/home/jonny/tslib/plugins’

        Makefile:483: recipe for target ‘install-recursive’ failed

        make: * [install-recursive] Error 1

    解決方案

    原因：sudo指令使用的是root的環境變量，sudo就找不到ARM-GCC了

    解決：添加ARM-GCC的絕對路徑就好了

$ ./configure CC=/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc \

            CXX=/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi-g++ \

            --prefix=/opt/tslib \

            --host=arm-linux-gnueabi \

            ac_cv_func_malloc_0_nonnull=yes

    檢視tslib

$ ls /opt/tslib/

    bin etc include lib share

編譯Qt4.8.7

    下載下傳qt-everywhere-opensource-src-4.8.7.tar.gz

    編譯安裝Qt

$ sudo mkdir /opt/qte4.8.7

$ make -j 4

$ sudo make install

        make3: Leaving directory ‘/home/jonny/qt-everywhere-opensource-src-4.8.7/tools/linguist/linguist’

        make2: Leaving directory ‘/home/jonny/qt-everywhere-opensource-src-4.8.7/tools/linguist’

        Makefile:339: recipe for target ‘sub-linguist-make_default-ordered’ failed

        make1: * [sub-linguist-make_default-ordered] Error 2

        make1: Leaving directory ‘/home/jonny/qt-everywhere-opensource-src-4.8.7/tools’

        Makefile:742: recipe for target ‘sub-tools-make_default-ordered’ failed

        make: * [sub-tools-make_default-ordered] Error 2

        — 解決方案：configure項添加 -nomake tools 或者直接忽視之

        Makefile:1054: recipe for target ‘.moc/release-shared-emb-arm/moc_qabstractanimation.cpp’ failed

        make1: * [.moc/release-shared-emb-arm/moc_qabstractanimation.cpp] Error 2

        make1: * 正在等待未完成的任務….

        Makefile:1314: recipe for target ‘.moc/release-shared-emb-arm/moc_qvariantanimation.cpp’ failed

        make1: * [.moc/release-shared-emb-arm/moc_qvariantanimation.cpp] Error 2

        Makefile:1433: recipe for target ‘.moc/release-shared-emb-arm/moc_qpropertyanimation.cpp’ failed

        make1: * [.moc/release-shared-emb-arm/moc_qpropertyanimation.cpp] Error 2

        make1: Leaving directory ‘/home/jonny/qt-everywhere-opensource-src-4.8.7/src/corelib’

        Makefile:201: recipe for target ‘sub-corelib-make_default-ordered’ failed

        make: * [sub-corelib-make_default-ordered] Error 2

        解決方案：一般都是編譯器路徑有問題導緻的，檢查qmake.conf檔案

    檢視Qt版本

$ cd /opt/qte4.8.7/bin/

$ ./qmake -v

    QMake version 2.01a

    Using Qt version 4.8.7 in /opt/qte4.8.7/lib

至此，Qt4.8.7交叉編譯完成。
