我已成功编译以下程序
Set<InetSocketAddress>
当我尝试使用Python解释器执行classes模块时,收到以下错误:
#include <boost/python.hpp>
#include <boost/python/list.hpp>
#include <boost/python/extract.hpp>
#include <string>
#include <sstream>
#include <vector>
struct World
{
void set(std::string msg) { mMsg = msg; }
void many(boost::python::list msgs) {
long l = len(msgs);
std::stringstream ss;
for (long i = 0; i<l; ++i) {
if (i>0) ss << ", ";
std::string s = boost::python::extract<std::string>(msgs[i]);
ss << s;
}
mMsg = ss.str();
}
std::string greet() { return mMsg; }
std::string mMsg;
};
using namespace boost::python;
BOOST_PYTHON_MODULE(classes)
{
class_<World>("World")
.def("greet", &World::greet)
.def("set", &World::set)
.def("many", &World::many)
;
};
我正在使用:
我使用以下clang ++命令编译程序:
Python 3.6.2 |Anaconda custom (x86_64)| (default, Sep 21 2017, 18:29:43)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import classes
>>> classes.World()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __init__() should return None, not 'NoneType'
我检查了我的* .so文件是否正确链接:
clang++ -o classes.so -shared -fPIC\
-L/usr/local/anaconda/lib \
-lboost_python3 \
-lpython3.6m \
-I/usr/local/anaconda/include \
-I/usr/local/anaconda/include/python3.6m \
classes.cpp
我已经检查了以下问题https://stackoverflow.com/questions/20437769,但是,在我的情况下,似乎我已经将我的程序与优秀的Python库相关联(与导入模块的Python安装相同)。
我该如何解决?
