Are these correct?([y]/n):

Warning: Mex requires that the Microsoft Visual C++ 6.0
directories "VC98" and "Common" be located within the same parent directory.
(Expected to find a directory named "Common" in the directory 'd:\software\C_installer'.)?? 強烈懷疑是安裝vc++時候,文件夾不統一,這個可能會造成一些問題..

顯然,自己沒有安裝vc98
