我只是想在我的mac OS X 10.5 Leopard上编译基于linux的FCEUX（NES模拟器）。
我得到了所有依赖项（SDL，GTK + 2）以及除了所有事情之外的所有事情现在这是我的问题：

这些是zlib函数。好像它正在加载zlib.h确定，但符号没有链接？只是为了确保我下载了最新的zlib并进行了make install，没有任何帮助。我不知道这里发生了什么，似乎它应该是非常基本的，库不是什么特别的。帮助将不胜感激。感谢。
编辑：这是链接列表：

答案 0 :(得分：2)
我挖到了scons找到答案。
我将此添加到SConstruct文件（在其中一个非win32部分中）：
env['LIBS'] = ['z']
认为这对FCE团队是值得一提的，还是这个在linux机器上通常不是问题？
