今天我把qt重新编译成了静态库，用的-debug-and-release -static选项，然后我用qt creator新建了一个动态c++链接库。按照默认的设置是能够成功生成*.o文件，可我想生成dll文件，所以我在配置文件里加了“config+=dll”，但是能够成功生成debug版的dll文件，但是不能生成release版的dll文件。
下面是配置文件：
- TARGET = DynamicTest
- TEMPLATE = lib
- DEFINES += DYNAMICTEST_LIBRARY
- SOURCES += dynamictest.cpp
- HEADERS += dynamictest.h\
- DynamicTest_global.h
- CONFIG += dll
头文件：
- #ifndef DYNAMICTEST_H
- #define DYNAMICTEST_H
- #include "DynamicTest_global.h"
- #include <QtGui/QDialog>
- class DYNAMICTESTSHARED_EXPORT DynamicTest:public QDialog {
- public:
- DynamicTest(QWidget *parent=0);
- };
- #endif // DYNAMICTEST_H
源文件：
- #include "dynamictest.h"
- DynamicTest::DynamicTest(QWidget *parent):QDialog(parent)
- {
- }
下面是错误信息：

请各位看看是什么原因。
