无法在 Mac 上运行 Ubuntu 上编译的共享库

Question

我在ubuntu机器上编译了一个cpp文件，并使用以下命令生成了链接器：

g++ -c -fPIC foo.cpp -o foo.o
g++ -shared -Wl,-soname,libfoo.so -o libfoo.so  foo.o

然后我在 python 中加载了 libfoo.so 链接器文件，如下所示。

from ctypes import *
lib = cdll.LoadLibrary('./lib/cppFunctions/libfoo.so')

然后我可以在ubuntu上使用python使用cpp文件中的函数。

但是，当我尝试在 Mac 上加载 .so 文件 (libfoo.so) 时，出现以下错误。

OSError: dlopen(./lib/cppFunctions/libfoo.so, 6): no suitable image found.  Did find:
    ./lib/cppFunctions/libfoo.so: unknown file type, first eight bytes: 0x7F 0x45 0x4C 0x46 0x02 0x01 0x01 0x00

完整错误：

如何让.so文件在mac上运行？
