安裝Qt precompile

http://download.qt.io/official_releases/qt/5.9/5.9.2/qt-opensource-linux-x64-5.9.2.run 
chmod u+x qt-opensource-linux-x64-5.9.2.run 
./qt-opensource-linux-x64-5.9.2.run 
進入安裝界面，進行安裝 
安裝完成之後進入安裝目錄運行QtCreator

添加環境變量

## QT
QT_VERSION=5.10.1
QT_PATH=/home/shihyu/"Qt"${QT_VERSION}
export LD_LIBRARY_PATH=${QT_PATH}/Tools/QtCreator/lib:${QT_PATH}/Tools/QtCreator/lib/qtcreator:${QT_PATH}/Tools/QtCreator/lib/Qt/lib:$LD_LIBRARY_PATH
export PATH=${QT_PATH}/${QT_VERSION}/gcc_64/bin:${QT_PATH}/Tools/QtCreator/bin:$PATH

執行qtcreator

qtcreator

QtCreator無法輸入中文

設置環境變量export QT_IM_MODULE=iBus

自行編譯

cd qt-everywhere-opensource-src-5.8.0
./configure -prefix `pwd`/build/ -debug -nomake tests
make -j8
make install

完成編譯安裝

• ~/.bashrc

因為我是將Qt 裝在自己的home directory, 所以$HOME/Qt/src/qt-everywhere-opensource-src-5.8.0/build/bin 裡面有一個qmake的程式, 通常Linux也會內建一個qmake程式, 有時這兩個版本會不相容. 所以當你要執行qmake這個程式時, 請確定是執行到$HOME/Qt/src/qt-everywhere-opensource-src-5.8.0/build/bin/qmake. 通常只要注意path設定的先後順序, 如下, 應該就沒問題:

export PATH=$HOME/Qt/src/qt-everywhere-opensource-src-5.8.0/build/bin/:$PATH 

在執行qmake -v的話，會有qmake 會把lib路徑指定編譯的路徑

# qmake -v
QMake version 3.1
Using Qt version 5.8.0 in /home/shihyu/qt-everywhere-opensource-src-5.8.0/build/lib

Hello Qt test

• hello.cpp

#include <QApplication>
#include <QLabel>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);

    QLabel* label = new QLabel(
        "<h1><font color=blue>Hello!World!</font><font color=red>Orz...</font></h1>");
    label->setWindowTitle("First Qt!");
    label->resize(200, 50);
    label->show();

    return app.exec();
}

mkdir hello_qt
cd hello_qt
qmake -project
vim hello_qt.pro
QT+=widgets
qmake
make
./hello_qt

• 通常只有指定PATH, qmake 就會指定編譯的lib 路徑
