我尝试构建 cgal-python 并出现以下错误(只是一个片段):
In file included from /opt/local/include/boost/config.hpp:40,
from /opt/local/include/CGAL/config.h:37,
from /opt/local/include/CGAL/basic.h:28,
from Kernel_module.cpp:21,
from All_files_at_once.cpp:1:
/opt/local/include/boost/config/select_stdlib_config.hpp:17:19: error: cstddef: No such file or directory
MacOS Lion 上标准 C 库的头文件在哪里?
