Thanks Jim for his kindly reply.I've created a vecstring.sip from qstrlist.sip
and a a.sip to wrap:
#include <vector>
#include <string>
using namespace std;
class A {
public: 
	A();
	~A();
    void foo(const vector<string>&,vector<string>&);
};

The a.sip looks like:
%Module A
%Include vecstring.sip

%HeaderCode
#include "a.h"
%End

class A{
public:
void foo(const VecString&,VecString&);
};

and the vecstring.sip is in attachment.

The compile progress is ok with the following output:

/usr/local/bin/sip -s ".cpp" -c sip a.sip
cd sip && make
make[1]: Entering directory `/home/zl/prj/py/py/sip'
g++  -c -I.. -I. -I/usr/include/python2.1 -I/usr/local/include/sip  
Acmodule.cpp
g++  -c -I.. -I. -I/usr/include/python2.1 -I/usr/local/include/sip  sipAA.cpp
g++ -shared -L/usr/local/lib/ -lsip -o libAcmodule.so *.o
make[1]: Leaving directory `/home/zl/prj/py/py/sip'

When I try to import A from python interpreter a error occurs:

>>> import A
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in ?
    import A
  File "/home/zl/prj/py/py/sip2/A.py", line 5, in ?
    import libAc
ImportError: /home/zl/prj/py/py/sip2/libAcmodule.so: undefined symbol:

>>> import A

Seems like a linking problem but I'm not sure.
Can you tell me where is the problem?
