【求助】恳请高手帮忙

我是按照 adams 帮助里的讲解做的 天线仿真的例子， 不过我是反过来做的，  
  
使用 adams 调用 matlab 做的，但到最后出现这样的问题：  
  
### Starting Real-Time Workshop build procedure for model: antenna  
### Generating code into build directory: .\antenna_grt_rtw  
### Invoking Target Language Compiler on antenna.rtw  
tlc -r .\antenna_grt_rtw\antenna.rtw 'D:\MATLAB6p1\rtw\c\grt\grt.tlc' -O.\antenna_grt_rtw '-ID:\MATLAB6p1\rtw\c\grt' '-ID:\MATLAB6p1\rtw\c\tlc' -aEnforceIntegerDowncast=1 -aExtMode=0 -aFoldNonRolledExpr=1 -aForceParamTrailComments=0 -aGenerateComments=1 -aIgnoreCustomStorageClasses=1 -aIncHierarchyInIds=0 -aInlineInvariantSignals=0 -aInlineParameters=0 -aLocalBlockOutputs=1 -aLogVarNameModifier="rt_" -aRTWVerbose=1 -aRollThreshold=5 -aShowEliminatedStatements=1 -aReleaseVersion=12.1 -p10000  
### Loading TMW TLC function libraries  
..  
### Initial pass through model to cache user defined code  
### Caching model source code  
...  
### Creating (RealTime) source file antenna.c  
### Creating model header file antenna.h  
### Creating model header file antenna_export.h  
### Creating parameter file antenna_prm.h  
### Creating registration file antenna_reg.h  
.  
### TLC code generation complete.  
### Creating project marker file: rtw_proj.tmw  
### Creating antenna.mk from D:\abs_test\shiyan\grt_vc.tmf  
### Building antenna: nmake -f antenna.mk  
'nmake' 不是内部或外部命令，也不是可运行的程序  
或批处理文件。  
  
   请问这怎么解决 ？  
  
   谢谢！！！！！！！！！！！！！
