//Q_EXPORT_PLUGIN2(Aliplugin, Alipay) ///if i write two Q_EXPORT_PLUGIN2, the compiler will report error

Q_EXPORT_PLUGIN2(Aliplugin, AlipluginPlugin)
//Q_EXPORT_PLUGIN2(Aliplugin, Alipay) ///if i write two Q_EXPORT_PLUGIN2, the compiler will report error

Which error, can you write ?

[hsany330]

alipay.cpp:23: error: expected constructor, destructor, or type conversion before '(' token
make: *** [obj/alipay.o] Error 1

Are you using semicolon ( ; ) at the end, remove it.

or show us code, with EXPORT plugin line.
