1. 起源

目标平台为arm架构，无x64或windows安装包

http://download.qt-project.org/archive/qt/5.9/5.9.8/

 2. 下载qt-everywhere

http://download.qt-project.org/archive/qt/5.9/5.9.8/single/

tar.xz，这是两层压缩，外面是xz压缩，里层是tar压缩，所以分两步实现解压。

# xz -d qt-everywhere-opensource-src-5.9.8.tar.xz
# tar -xvf qt-everywhere-opensource-src-5.9.8.tar.xz

也可以直接解压
# tar -xvJf qt-everywhere-opensource-src-5.9.8.tar.xz

 解压完成

3.2 问题：make:g++:命令未找到

sudo apt-get install g++

3.3 configure编译配置

报错1

Qt5.5.1 configure编译选项,在这里不再介绍。
配置生成make文件时不报错，就可以make了。

$ cd qt-everywhere-opensource-src-5.5.1/
$ sudo ./configure 
    -prefix /opt/qte5.5.1 
    -confirm-license 
    -opensource 
      -shared 
    -release  
    -make libs 
    -xplatform linux-arm-gnueabi-g++ 
    -optimized-qmake 
    -pch 
    -qt-sql-sqlite 
    -qt-libjpeg 
    -qt-libpng 
    -qt-zlib 
    -no-opengl 
    -no-sse2 
    -no-openssl 
    -no-cups 
    -no-glib 
    -no-dbus 
    -no-xcb 
    -no-xcursor -no-xfixes -no-xrandr -no-xrender 
    -no-separate-debug-info 
    -no-fontconfig 
    -nomake examples -nomake tools -nomake tests -no-iconv 
    -tslib 
    -I/opt/tslib/include 
    -L/opt/tslib/lib 

ERROR: Invalid value given for boolean command line option 'sql-sqlite'.
ERROR: Unknown command line option '-no-xcursor'.

修改后

sudo ./configure 
    -prefix /opt/qte5.5.1 
    -confirm-license 
    -opensource 
      -shared 
    -release  
    -make libs 
    -xplatform linux-arm-gnueabi-g++ 
    -optimized-qmake 
    -pch 
    -qt-libjpeg 
    -qt-libpng 
    -qt-zlib 
    -no-opengl 
    -no-sse2 
    -no-openssl 
    -no-cups 
    -no-glib 
    -no-dbus 
    -no-xcb 
    -no-separate-debug-info 
    -no-fontconfig 
    -nomake examples -nomake tools -nomake tests -no-iconv 
    -tslib 
    -I/opt/tslib/include 
    -L/opt/tslib/lib 

报错2

 arm-linux-gnueabi-g++

 ==>

sudo apt-get  install gcc-arm-linux-gnueabi

sudo apt-get install g++-arm-linux-gnueabi

 

 报错3

 

ERROR: Feature 'tslib' was enabled, but the pre-condition 'libs.tslib' failed.

ERROR: Feature 'tslib' was enabled, but the pre-condition 'libs.tslib' failed.
ERROR: Feature 'system-sqlite' was enabled, but the pre-condition 'libs.sqlite3' failed.

解决：tslib和sqlite3要预先编译并指定路径或者配置末尾加上-recheck-all选项。
