Windows中的psycopg2链接错误

Question

我只是用visualstudio在Windows中构建psycopg2模块。 我已经安装了VisualStudioforPython2.7。 编译后，我得到以下链接错误：

Creating library build\temp.win32-2.7\Release\psycopg\_psycopg.lib and    
object build\temp.win32-2.7\Release\psycopg\
_psycopg.exp

pqpath.obj : error LNK2019: unresolved external symbol _PQerrorMessage

有人能指导我们如何用visualstudio在windows中构建psycopg2和pcrypto模块吗？在

提前谢谢。在
