qt5.5.1在Cortex-a8上移植記錄
阿新 • • 發佈：2018-12-20
使用Qt5.5.1原始碼包進行編譯：下載地址 http://download.qt.io/official_releases/qt/
tslib1.4編譯
1.解壓並進入Tslib目錄2.gedit tests/ts_calibrate.c 230行在open的引數傳入增加一個引數，0777
if ((calfile = getenv("TSLIB_CALIBFILE")) != NULL)
{
cal_fd = open (calfile, O_CREAT | O_RDWR,0777);
}
else
{
cal_fd = open ("/etc/pointercal", O_CREAT | O_RDWR,0777);
}
3.拷貝安裝指令碼並執行 installTslib.sh
#!/bin/sh
./autogen.sh
make clean && make distclean
echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache
CC=arm-fsl-linux-gnueabi-gcc
./configure --host=arm-fsl-linux-gnueabi --prefix=/usr/local/arm/tslib1.4 --cache-file=arm-linux.cache
make && make installQt編譯
1、進入原始碼包根目錄，配置qtbase/mkspecs/linux-arm-gnueabi-g++/ qmake.conf
1 # 2 # qmake configuration for building with arm-linux-gnueabi-g++ 3 # 4 5 MAKEFILE_GENERATOR = UNIX 6 CONFIG += incremental 7 QMAKE_INCREMENTAL_STYLE = sublib 8 9 QT_QPA_DEFAULT_PLATFORM = linuxfb 10 QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a 11 QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a #cortex-a8 12 13 include(../common/linux.conf) 14 include(../common/gcc-base-unix.conf) 15 include(../common/g++-unix.conf) 16 17 # modifications to g++.conf 18 QMAKE_CC = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-gcc 19 QMAKE_CXX = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-g++ 20 QMAKE_LINK = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-g++ 21 QMAKE_LINK_SHLIB = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-g++ 22 23 # modifications to linux.c/usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi 24 QMAKE_AR = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-ar cqs 25 QMAKE_OBJCOPY = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-objcopy 26 QMAKE_NM = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-nm -P 27 QMAKE_STRIP = /usr/local/arm/arm-linux-gcc-4.8.3/bin/arm-none-linux-gnueabi-strip 28 load(qt_config)
2、配置編譯選項
./configure -release -opensource -xplatform linux-arm-gnueabi-g++ -prefix /usr/local/qt -no-c++11 -no-opengl -no-dbus -no-icu -no-eglfs -no-iconv -I/usr/local/tslib/include -L/usr/local/tslib/lib

Info: creating super cache file /home/djq/Downloads/qt-everywhere-opensource-src-5.5.0/.qmake.super
Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/qt
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.3、sudo make -j4 & sudo make install
方案1：主要原因是它依賴的dbus目錄沒有編譯，解決方法如下：
#cd /home/hello/qt-everywhere-opensource-src-5.4.0/qtbase/src/dbus執行下面的
如沒有Makefile,執行下面的命令
#../../bin/qmake dbus.pro
然後執行Make.
#make
編譯成功後，再切換到/home/hello/qt-everywhere-opensource-src-5.4.0目錄下，執行
#make
方案2：-no-dbus (注：當前使用方案)
問題2：make報錯module-qt3d-install_subtargets 錯誤（參考http://my.oschina.net/u/1177171?disp=2&catalog=0&sort=time&p=1大嬸的部落格，灰常感謝）
方案1：在編譯之前，還有個改動，額。。。qt3d和qtcanvas3d在編譯的時候會報錯，說是未識別模組，而且嵌入式的沒有opengl，識別了也會報錯，導致編譯失敗，而且編譯配置引數裡面也沒有這兩個模組的配置。我的解決方法簡單粗暴，在配置時引數加-no-opengl，然後開啟qt-everywhere-opensource-src-5.5.0/qt.pro檔案，找到：
addModule(qt3d, qtdeclarative qtimageformats)
addModule(qtcanvas3d, qtdeclarative)
這兩行註釋掉（#號註釋），或者直接刪掉。如果不註釋掉，即使加了-no-opengl也會報錯，編譯失敗。
問題3：
make[3]: arm-none-linux-gnueabi-g++：命令未找到
make[3]: *** [.pch/Qt5WebChannel.gch/c++] 錯誤 127
make[3]:正在離開目錄 `/home/djq/Downloads/qt-everywhere-opensource-src-5.5.0/qtwebchannel/src/webchannel'
make[2]: *** [sub-webchannel-install_subtargets] 錯誤 2

make[1]:正在離開目錄 `/home/djq/Downloads/qt-everywhere-opensource-src-5.5.0/qtwebchannel'
make: *** [module-qtwebchannel-install_subtargets] 錯誤 2
方案1：修改qmake.conf檔案的交叉編譯工具位置，設定為絕對路徑錯誤消除。
4、板卡/etc/profile設定,使用Evdevtouch
