使用Emscripten

Question

我试图编译下面的代码编译GLUT -s LEGACY_GL_EMULATION = 1 -lglut -lGLU -lGL

我得到了以下警告：

warning: unresolved symbol: glPointSize 
warning: unresolved symbol: glutSolidSphere 
warning: unresolved symbol: glutWireSphere 

而且这些都是错误的：

WARNING: using emscripten GL immediate mode emulation. This is very limited in what it supports 

missing function: glPointSize

为什么说glPointSize不见了？

这些转运蛋白由Emscripten支持的特性： https://github.com/kripken/emscripten/blob/master/src/library_glut.js

为了画的东西，例如一个球体，Kripken建议某处寻找用C语言编写，通过本身，然后再执行它的功能，将该功能移植到我的程序中。
