分析：C:\Program Files (x86)\Microsoft Visual Studio 9.0\Vc\bin\nmake.exe /nologo tbuild，由这一句分析应该是nmake.exe的路径问题导致找不到nmake.exe，再看一下前面的路径容易发现，Program Files(x86)文件夹，就应该明白问题大概出在哪里了。虽然自己电脑是32位的，但好像有些机器C盘下的Program Files文件夹后面却不带(x86)

解决方案：所以最保险的方法还是看一下自己C盘下的Program Files后到底带不带(x86)，之后，在修改target.txt中TOOL_CHAIN_TAG这一项的时候，决定是修改成VS2015x86还是VS2015，具体支持VS的哪些版本还是要看tools_def.txt文件。
