Question

我一直在研究Java和Python等几种编程语言，最近我开始使用C ++。我想建立一个GUI程序，最后我被建议使用FLTK，据说它是轻量级的，用户友好的。但是，我被告知要安装一系列第三方工具，而我仍然无法弄清楚如何创建一个简单的GUI应用程序。

我第一次被告知要安装一个巨大的IDE Dev-C++并下载FLTK源代码（获得here）。然后互联网上的一些“教程”也建议我安装一个FLTK软件包（获得here），而我找不到任何关于如何实际“导入”库的教程或文档（我的意思是，类似于指定Java中的类路径和导入类）。我最终尝试将FLTK源代码复制到Dev-C ++文件夹Dev-Cpp\MinGW64\x86_64-w64-mingw32\include，创建了一个FLTK项目并开始编译以下代码（自动生成）：

#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Box.H>

int
main(int argc, char ** argv)
{
    Fl_Window *window;
    Fl_Box *box;

    window = new Fl_Window(300, 180);
    box = new Fl_Box(20, 40, 260, 100, "Hello World!");

    box->box(FL_UP_BOX);
    box->labelsize(36);
    box->labelfont(FL_BOLD+FL_ITALIC);
    box->labeltype(FL_SHADOW_LABEL);
    window->end();
    window->show(argc, argv);

    return(Fl::run());
}

而不是成功编译，出现的是错误消息:(从编译日志复制）

我真的不知道该怎么办。在我看来，C ++是一种支持缺乏和未开发的编程语言，真的很糟糕。请帮助我，或者至少给我一些提示，创建一个简单的GUI，并纠正我的误解，如果有的话。提前谢谢。

将FLTK与Dev-C ++一起使用
