如何在linux下编译fltk
我现在 下载了fltk的1.17在redhat9中进行了安装，但是在启动fluid生成界面后却不知道该如何去编译，因为按照帮助文档里提供的hello.cxx 利用gcc －o myhello myhello.cxx｀fltk－config －－cxxflag｀ －l／usr／local／lib －X11 －Xext －lm进行编译，但是却出错有很多错误，首先是X11找不到，随后是不存在Xext ，
我的源代码hello.cxx
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Box.H>
int main(int argc, char **argv) {
Fl_Window *window = new Fl_Window(300,180);
Fl_Box *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();
}
我当时用的命令是
gcc `fltk-config --cxxflags` -o myhello hello.cxx -L/usr/local/lib -I/usr/local/include/FL -lfltk -L/usr/X11R6/lib -lXext -lX11 -lm
编译时出的错误

这个错误长了些所以只把最重要的传了上来。还请多多指点。
请各位高手指点一二，不胜感激！多谢！
