build the Linux kernel for OMAP-L138 LCDK

Hello,I'm building the Linux kernal for OMAPL38 LCDK refer to this paper ( http://processors.wiki.ti.com/index.php/OMAP-L138_LCDK_Linux_Software_Developer%27s_Guide#Steps_to_export_an_NFS_mount ) 

host $ ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- make uImage ' in host command line,something goes wrong.The host command line reply 





'  make : arm-arago-linux-gnueabi-gcc : command not found
  

  
         CHK           include/linux/version.h
 


         CHK           include/generated/utsrelease.h



  make[1]:  "include/generated/mach-types.h" is the latest


        
         CC     kernel/bounds.s  



  /bin/sh :  1 :  arm-arago-linux-gnueabi-gcc :  not found 



 make[1] :  [kernel/bounds.s]  error 127



 make:   [prepare0]  error 2  '  



I don't think it is because of the problem of  GCC Tool Chain's path,for theformer command 


' host $ ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- make menuconfig' executed successfully.



Regards,

Sai.
