Example of boost/python/call_method.hpp does not compile

從 my_module.cpp 範例開始，使用 Python 3.6 的 include 路徑重現報告中的 gcc 命令。檢查範例的標頭檔，確認其是否對應報告中缺少的 call_method 和 def 宣告；完成的標準是範例包含所需的 Boost.Python 標頭檔，並且能夠在沒有這些錯誤的情況下編譯。

I compilled the my_module.cpp file with the following command:
gcc -o my_module.o my_module.cpp -c -Wall -fPIC -I/usr/include/python3.6

This resulted in the following error:

my_module.cpp: In member function ‘virtual const char* Base_callback::class_name() const’:
my_module.cpp:31:44: error: ‘call_method’ was not declared in this scope
    char const* class_name() const { return call_method<char const*>(m_self, "class_name"); }
                                            ^~~~~~~~~~~

     ^~~
makefile:16: recipe for target 'my_module.o' failed

The solution was to add the following 2 include statements:

#include <boost/python/call_method.hpp>
#include <boost/python/def.hpp>
