Question

我试图在我的Windows 7 64位计算机上使用Qt 5.3.1来访问第三方制造商提供的库，用于控制包含.DLL，标题的Performax步进控制器PMX-4EX-SA-TB9和lib文件。我在Visual C ++ studio中编写了一个命令提示程序，它连接得很好，但现在我想重写所有内容并使用Qt来制作一个更好看的程序。我的界面工作正常，我还没有编写任何专门使用该库的代码，我到目前为止只编写了所有按钮魔法，现在我想让它运行起来。

我的专业档案如下：

INCLUDEPATH += E:\qtTesting\ArcusTestInterface
QT          += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET   = ArcusTestInterface
TEMPLATE = app
SOURCES  += main.cpp\
            mainwindow.cpp
HEADERS  += mainwindow.h\
         += PerformaxCom.h
LIBS     += -LE:\qtTesting\ArcusTestInterface -lPerformaxCom
FORMS    += mainwindow.ui

我的lib，header和dll文件都与其他所有文件夹在同一个文件夹中，我还将DLL的副本放在调试文件夹中，试图使其工作正常。 QtCreator自动将头文件引入项目文件夹结构资源管理器，我可以双击该文件，看看我的构建问题在哪里。

这是头文件的副本

在第38行构建期间出现错误，第一行像BOOL PERFORMAXCOM_API一样启动：语法错误：＆＃39; int＆＃39;之前应该是＆＃39 ;;＆＃39;和缺少的类型说明符 - 假定的int和＆＃39; IN＆＃39; ：未声明的标识符和＆＃39; fnPerformaxComUSBReset＆＃39; ：不允许定义dllimport数据。请帮我。我的界面都经过精心设计，我正在阅读以开始编码，而我却无法克服这个小小的障碍。以下是错误的屏幕截图： Error Screen Shot

谢谢！
