为SWIG指定Python头和库。

I have two versions of python installed 2.7 and 3.3.

我安装了两个版本的python 2.7和3.3。

And when I tried to generate the wrapper with SWIG 1.3.4, I did something like this:

当我尝试用SWIG 1.3.4来生成包装时，我做了如下的事情:

swig -c++ -python -I/opt/rh/python33/root/usr/include/python3.3m mylib.swig

And then, I tried to compile it with g++ 4.6

然后，我试着用g+ 4.6编译它

g++ -L/opt/rh/python33/root/usr/lib64 -Wl,-Bstatic -lz -lboost_date_time-mt -Wl,-Bdynamic -lpython3.3m -lbz2 -lpthread -lrt -ldl -O2 -fPIC -shared mylib_wrap.cxx -I.. -I/opt/rh/python33/root/usr/include/python3.3m -I/server/zodiac/include -std=gnu++0x -o _mylib.so

But then, I got error like this:

但是，我有这样的错误:

mylib_wrap.cxx: In function ‘swig_module_info* SWIG_Python_GetModule()’:
mylib_wrap.cxx:2453:51: error: ‘PyCObject_Import’ was not declared in this scope
mylib_wrap.cxx: In function ‘void SWIG_Python_SetModule(swig_module_info*)’:
mylib_wrap.cxx:2522:92: error: ‘PyCObject_FromVoidPtr’ was not declared in this scope
mylib_wrap.cxx: In function ‘swig_type_info* SWIG_Python_TypeQuery(const char*)’:
mylib_wrap.cxx:2545:60: error: ‘PyCObject_AsVoidPtr’ was not declared in this scope
mylib_wrap.cxx:2550:51: error: ‘PyCObject_FromVoidPtr’ was not declared in this scope

Then, I looked into Python 2.7's and 3.3's headers. I noticed that those expressions are defined in Python 2.7's headers but not 3.3.

然后，我研究了Python 2.7和3.3的头部。我注意到这些表达式是在Python 2.7的header中定义的，而不是在3.3中定义的。

So it seems to me even though I specified the include path to Python 3.3 when I asked SWIG to generate the wrapper, it still tried to use 2.7.

所以在我看来，即使我指定了Python 3.3的包含路径，当我要求SWIG生成包装器时，它仍然尝试使用2.7。

Any idea how to fix this?

你知道怎么解决这个问题吗?

Thanks!

谢谢!

SWIG 1.3.4 is ancient. It's not compatible with Python 3.3. You need to use a newer version of SWIG if you want to produce code that is compatible.

痛饮1.3.4是古老的。它与Python 3.3不兼容。如果您想生成兼容的代码，需要使用SWIG的更新版本。
