先安装基本的库，用aptget可以自动安装依赖
sudo apt-get install libfltk1.1-dev libfltk1.1下载一个最新的源代码，编译
tar avzf fltkxxx
cd fltkxxx./configuremake sudo make installcutepig@ubuntu:~/Downloads/fltk-1.3.0$ sudo make install=== installing FL ===Installing include files in /usr/local/include...=== installing jpeg ===Installing ../lib/libfltk_jpeg.a in /usr/local/lib...Installing jpeg headers in /usr/local/include/FL/images...=== installing zlib ===Installing libfltk_z.a in /usr/local/lib...Installing zlib headers in /usr/local/include/FL/images...=== installing png ===Installing libfltk_png.a in /usr/local/lib...Installing png headers in /usr/local/include/FL/images...=== installing src ===Installing libraries in /usr/local/lib...=== installing fluid ===Installing FLUID in /usr/local/bin...=== installing test ===Installing example programs to /usr/local/share/doc/fltk/examples...=== installing documentation ===Installing documentation files in /usr/local/share/doc/fltk ...Installing man pages in /usr/local/share/man ...cutepig@ubuntu:~/Downloads/fltk-1.3.0$ 写一个例子程序#include <FL/Fl.H>#include <FL/Fl_Window.H>#include <FL/Fl_Button.H> int main(int argc, char *argv[]) { Fl_Window* w = new Fl_Window(330, 190); new Fl_Button(110, 130, 100, 35, "Okay"); w->end(); w->show(argc, argv); return Fl::run();}编译运行g++ test.cpp -lfltk -lX11 -lm
