从源码编译 Qt

这里介绍了ARM平台交差编译和x86平台编译

下载解压

qt-everywhere-opensource-src-4.8.1.tar.gz
tar xvzf qt-everywhere-opensource-src-4.8.1.tar.gz
cd /qt-everywhere-opensource-src-4.8.1

交差编译,安装交差编译器

sudo apt-get install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf

交差编译,替换arm-linux-g++ 为 arm-linux-gnueabihf-g++ 等一系列

vi mkspecs/qws/linux-arm-g++/qmake.conf
:%s/arm-linux-/arm-linux-gnueabihf-/g

交差编译,不带 webkit 编译

./configure -embedded arm -xplatform qws/linux-arm-g++ -nomake demos -nomake docs -nomake examples -no-webkit -prefix /opt/qt-4.8.1-arm -little-endian -host-little-endian

交差编译,带 webkit 编译

add /usr/include/openssl/opensslconf.h
./configure -embedded arm -xplatform qws/linux-arm-g++ -nomake demos -nomake docs -nomake examples -prefix /opt/qt-4.8.1-arm -little-endian -host-little-endian

x86编译

./configure -fontconfig -nomake demos -nomake examples -prefix /opt/qt-4.8.1-x86

多核并发make

make -j4
sudo make install
