使用qmake编译时出错，qt？

Question

我尝试编写一个简单的qt应用程序，当我尝试编译它时出现此错误

#include <QApplication>
#include <QTextEdit>

int main(int argv, char **args)
{
    QApplication app(argv, args);

    QTextEdit textEdit;
    textEdit.show();

    return app.exec();
}

_

qmake file.cpp

/home/j/qtf.cpp:4: Extra characters after test expression.
/home/j/qtf.cpp:6: Extra characters after test expression.
/home/j/qtf.cpp:8: Extra characters after test expression.
/home/j/qtf.cpp:11: Extra characters after test expression.

错误在哪里

Answer 1

为了编译您的应用程序，您必须：

• 创建项目文件
• 生成makefile，
• 构建项目。

要执行这些步骤，只需调用相应的命令：

qmake -project (generates project file)
qmake          (generates makefile)
make           (build the project)
