C++；包括问题 我用C++编写了Autodesk Maya的插件，并有链接错误。p>

我的主要课程是Maya\u Search\u Plugin.cpp

#include <Utilities.h>

DeclareSimpleCommand( search_face, PLUGIN_COMPANY, "4.5");

//doIt method is entry point for plugin
MStatus search_face::doIt( const MArgList& )
{
    //calls to Maya types/functions and Utilities functions
}

我认为这是一个链接错误，在某个地方有一些循环引用，但我不能确定它在哪里

谢谢你的帮助

谢谢。

我知道这已经一岁了。但几分钟前我又无意中发现了

在包含任何内容之前。例如。

如果您有多个包含MFnPlugin.h的文件，则可能会发生此问题。

Maya版本？XCode版本？Maya 2014，XCode 4.6.3是的，我在主类中使用宏，如devkit中的演示材料所示。您是否能够从SDK重建和使用插件示例？DeclareSimpleCommand（search_face，PLUGIN_COMPANY，“4.5”）；
