qt 源码 build 方法

./configure -prefix /usr/local/Trolltech/Qt-5.12.4-arm/ -release -opensource -make libs -xplatform linux-g++-32 -optimized-qmake -pch -qt-libjpeg -qt-zlib -no-opengl -skip qt3d -skip qtcanvas3d -skip qtpurchasing -no-sse2 -no-openssl -no-cups -no-glib -no-iconv -nomake examples -nomake tools -skip qtvirtualkeyboard

实际测试:

./configure -prefix /usr/local/Trolltech/Qt-5.12.4-arm/ -opensource -no-opengl 

qpaintervideosurface.cpp:67:12: error: invalid use of incomplete type 'class QGLContext'

     context->makeCurrent();

./configure -prefix /usr/local/Trolltech/Qt-5.12.4-arm/ -release -opensource -platform linux-g++ -make libs -optimized-qmake -pch -qt-libjpeg -qt-zlib -skip qt3d -skip qtcanvas3d -skip qtpurchasing -no-sse2 -no-openssl -no-cups -no-glib -no-iconv -nomake examples -nomake tools -skip qtvirtualkeyboard

去掉 -opengl 指定 -platform linux-g++

./configure -prefix /usr/local/Trolltech/Qt-5.12.4-arm/ -release -opensource -platform linux-g++ 

./configure -prefix /usr/local/Trolltech/Qt-5.12.4-arm/ -release -opensource -platform linux-g++ 

 -nomake docs -nomake examples -nomake demos -nomake tests

./configure -prefix /usr/local/Trolltech/Qt-5.12.4-arm/ -release -opensource -platform linux-g++ -nomake examples -nomake tests

交叉编译使用linux-arm-gnueabi-g++ 

make clean 清除编译

debian x86 安装 交叉编译器 apt-get install g++-arm-linux-gnueabihf

config 使用 平台 linux-arm-gnueabihf-g++ 

在 qtbase/mkspecs 中新建 linux-arm-gnueabihf-g++  编辑 qmake.conf 全部编译器改为 linux-arm-gnueabi-g++

查看文件格式 

file sqlite3-shell.o

sqlite3-shell.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped

 The OpenGL functionality tests failed!

解决方法 apt-get install libgl1-mesa-dev libglu1-mesa-dev 

注意 安装完以后 删除全部qt源码重新解压 后 错误才会消失
