我正在尝试使用 waf 在 osx 上构建一个 C++ opengl 程序，但无法让它工作。

通常当我编译一个 opengl 程序时，我在终端中使用它:

g++ main.cpp -framework GLUT -framework OpenGL

我使用以下 wscript:

top = '.'
out = 'build'

def options(opt):
    opt.load('compiler_cxx')

def configure(conf):
    conf.load('compiler_cxx')
    # conf.env.append_value('LINKFLAGS', '-framework GLUT -framework OpenGL')

def build(bld):
    bld.program(
      source       = 'main.cpp', 
      target       = 'a',
      linkflags    = ["-framework GLUT", "-framework OpenGL"], 
  )

但是我在构建它时遇到链接错误:

$ waf configure

有什么方法可以修复/执行此操作吗？

最佳答案

好吧，您的问题似乎是直接使用 LINKFLAGS 并带有诸如“-framework X”之类的参数。它会被 python 错误地解释。直接使用WAF提供的framework参数:

top = '.'
out = 'build'

def options(opt):
    opt.load('compiler_cxx')

def configure(conf):
    conf.load('compiler_cxx')

def build(bld):
    bld.program(
        source       = 'main.cpp', 
        target       = 'a',
        framework    = ["GLUT", "OpenGL"], 
    )
