1. Install depencencies

# sudo add-apt-repository universe
sudo apt-get update
# sudo apt-get install git build-essential
sudo apt-get install qtbase5-dev qt5-qmake libqt5serialport5-dev qtconnectivity5-dev 

2. Get the source code

cd ~
git clone https://github.com/wh201906/SerialTest.git --depth=1
cd SerialTest
mkdir build && cd build

3. Choose how to import QCustomplot

Use QCustomPlot source file（recommended）

You need to download QCustomPlot archive, extract the qcustomplot.cpp and qcustomplot.h in the /src folder(replace the existing qcustomplot.h), then build.

wget https://www.qcustomplot.com/release/2.1.1/QCustomPlot-source.tar.gz
tar -xzf QCustomPlot-source.tar.gz
cp qcustomplot-source/qcustomplot.* ../src

Use QCustomPlot library

If the qcustomplot.cpp doesn't exist in the src/ folder, the qmake will try to find the library file(xxx.so/xxx.dll) in the building directory(where you call the qmake command) and the default library directory.

4. Build and run

export QT_SELECT=qt5
qmake ../src
make -j4 && make clean
./SerialTest
