Am trying to install qt creator following these sequences suggested by a hardware provider...
正在尝试安装qt创建者，按照硬件提供者建议的这些序列…
sudo apt-get install libudev-dev
git clone git://code.qt.io/qt/qtserialport.git && cd qtserialport
git checkout origin/old/5.2
cd ..
mkdir qtserialport-build && cd qtserialport-build
qmake ../qtserialport/qtserialport.pro
make && sudo make install
cd ../qtserialport/ && git checkout origin/5.3
cd ../qtserialport-build/
make
But am getting errors at the last make:
但是在最后的时候会犯错误:
In file included from /home/polar/soft/lib/qt/qtserialport/src/serialport/qserialport.cpp:45:0:
/home/polar/soft/lib/qt/qtserialport/src/serialport/qserialport.h:190:44:
error: ‘Q_NULLPTR’ was not declared in this scope
explicit QSerialPort(QObject *parent = Q_NULLPTR);
^
On * some suggested to add QMAKE_CXXFLAGS += -std=c++0x, others CONFIG += c++11 to the .pro file. These did not work for me.... In fact there are at least two .pro files... which one I need amendment?
在*上，一些人建议添加QMAKE_CXXFLAGS += -std=c++0x，其他配置+= c++11到。pro文件。这些对我没用事实上，至少有两个。pro文件…哪一个我需要修改?
Any suggestions please?

the Q_NULLPTR is declared int the header file qserialportglobal.h ,so you just need to do is #include in the qserialport.h file
Q_NULLPTR被声明为头文件qserialportglobal。所以你只需要在qserialport中包含#include。h文件
