Makefile编译二进制文件，而不是executab

Question

在make之后运行可执行文件时，bash引发以下错误：

$ ./prog 
-bash: ./prog: cannot execute binary file

我的生成文件：

^{pr2}$

我做错什么了？在

更新2:

谢谢你的comment塞尔加亚。在this article的帮助下链接python之后，它就可以工作了。在

更新1:

我在一些注释之后删除了-undefined dynamic_lookup -bundle标志，因此我在使用Python时遇到了问题。要使用Python.h，我将环境变量设置为以下路径： CPLUS_INCLUDE_PATH=/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/

What did i wrong?

由于您显然想要一个可以直接执行的程序，所以错误之处在于将the ^{} option指定为g++。这指示它输出应该是Mach-obundle格式的文件。此类文件不能直接执行。它们可以在运行时通过系统的动态链接函数加载到另一个程序中，这些函数可用于实现插件和类似的程序功能。删除此选项。在

-undefined dynamic_lookup看起来也很可疑。我猜您是从其他Makefile复制了这个和-bundle选项。如果你不知道它在那里是为了什么，那么你也应该放弃它。在
