Qt行导致奇怪的错误: Cmd.exe退出，代码为-20
Qt行导致奇怪的错误: Cmd.exe退出，代码为-20
提问于 2021-09-02 16:45:46
我在两台不同的PC上构建我的项目，都使用相同的方法(带有CMake的Visual Studio2017)。它们使用CMake都可以很好地进行配置和生成。问题是，当我尝试构建它们时，一个构建得很好，而另一个却有错误。
我已经隔离了这个错误的原因，似乎每当我尝试实例化QLineSeries或QChart时都会出现这个错误。在我的代码下面没有红色的乱码。一切看起来都很好，直到我尝试实例化其中任何一个，然后出现了这些错误。
我经常使用QLineSeries (我有3个系列)，我慢慢地注释掉代码，直到我找到罪魁祸首。第一行，我尝试创建lineRedSeries = new QLineSeries;，结果如下所示的错误。此外，即使我注释掉所有内容并尝试创建QChart *chart = new QChart();，也会导致相同的错误。
奇怪的是，仅仅在h文件中声明QLineSeries和QChartView并不会导致这个问题(所以如果我注释掉cpp文件中的代码)。只有当我尝试创建QLineSeries或QChart时，才会出现错误。
我删除了许多与这个问题无关的不必要的函数，因为我的cpp文件相当长。
在我的main.h
#include <QtCharts> // for QLineSeries, QChartView, Chart
#include <QChartView>
class ExampleProject
{
public:
ExampleProject();
~ExampleProject();
private:
int OpenGraphic();
private:
QLineSeries *lineRedSeries, *lineGreenSeries, *lineBlueSeries;
QChartView *chartView;
};在我的main.cpp
#include "main.h"
#include <QApplication>
#include <QMainWindow>
#include <iostream>
int ExampleProject::OpenGraphic()
{
char *myargv[1];
int myargc = 1;
myargv[0] = strdup("");
// First, create QApplication
QApplication a(myargc, myargv);
// Create our lineChart Series
lineRedSeries = new QLineSeries; // The most FIRST line and causes errors!
lineRedSeries->setName("RedSeries");
lineRedSeries->setColor(Qt::red);
lineRedSeries->append(1, 20);
lineRedSeries->append(2, 30);
lineRedSeries->append(3, 44);
lineGreenSeries = new QLineSeries;
lineGreenSeries->setName("GreenSeries");
lineGreenSeries->setColor(Qt::green);
lineGreenSeries->append(1, 10);
lineGreenSeries->append(2, -9);
lineGreenSeries->append(3, 20);
lineGreenSeries->append(10, -40);
lineBlueSeries = new QLineSeries;
lineBlueSeries->setName("BlueSeries");
lineBlueSeries->setColor(Qt::blue);
lineBlueSeries->append(1, -20);
lineBlueSeries->append(2, -10);
lineBlueSeries->append(3, 0);
QChart *chart = new QChart();
chart->setTitle("Acceleration Graph");
chart->setAcceptHoverEvents(true);
// Add series to chart
chart->addSeries(lineRedSeries);
chart->addSeries(lineGreenSeries);
chart->addSeries(lineBlueSeries);
// Customize axes for chart
chart->createDefaultAxes();
chart->axes(Qt::Horizontal).back()->setRange(0, 131);
chart->axes(Qt::Vertical).back()->setRange(-50, 50);
chart->axes(Qt::Horizontal).back()->setTitleText("Time [s]");
chart->axes(Qt::Vertical).back()->setTitleText("Acceleration [m/s]");
// Create chartView
chartView = new QChartView(chart);
chartView->setRenderHint(QPainter::Antialiasing);
// Render everything within our Window
QMainWindow mainWindow;
mainWindow.setCentralWidget(chartView);
mainWindow.resize(400, 300);
mainWindow.show();
return a.exec();
}代码将导致以下错误：
the argument to a feature-test macro must be a simple identifier, qcompilerdetection.h, Line 1349

我想通了。
我在ADTF插件所在的目录中遗漏了一些非常重要的Qt .dll文件。一旦我移动了核心.dlls (Qt5Charts.dll、Qt5Core.dll、Qt5Gui.dl等)添加到正确的目录，并添加以下1行代码：
QCoreApplication:addLibraryPath("C:/Users/Path/To/Qt/msvc2017_64/plugins"); // this在我实例化我的QApplication之前，它起作用了！

ADTF不部署QtCharts二进制文件，因为许可证不兼容。Qt基本上是LGPL许可的，它与ADTF许可一起工作得很好。但有些组件是按照通用公共许可证授权的，QtCharts就是其中之一。您不允许将QtCharts与ADTF一起使用，因为这样会违反GPL中描述的组合工作规则。GPL不使用商业和封闭源代码许可证，只使用开源GPL兼容许可证，如GPL本身、MPL或其他。无论如何，因为缺少二进制文件，所以您会得到这样的错误:缺少一些依赖项。但是，即使您将二进制文件放在那里，也是不允许的，既不是私有的，也不是商业的。它不兼容，这就是为什么ADTF试图保护客户，只提供LGPL内容的原因。你甚至不允许使用开源Qt与ADTF一起使用商业Qt，因为Qt拒绝将oss与商业许可证混合在一起，即使这是相同的二进制(政治...)。唯一的机会，购买qtcharts独立从qt市场，然后它与LGPL兼容。但是你必须自己把这个二进制文件放进去。或者链接静态，这是由Qt提供的商业/市场许可证允许的。
