【已解决】cygwin下编译buildroot在Installing kernel headers期间出错：Makefile:1444: *** mixed implicit and normal rules. Stop.

【问题】

折腾：

【记录】在Cygwin上用Buildroot为xscale建立交叉工具链

期间，在Installing kernel headers期间，出错：

如图：

即：

【解决过程】

1.这个问题，很明显，是以前，在编译crosstool-ng时，就遇到过多次，并且通过：

【记录】Cygwin下把make从v3.82换成v3.81

已经彻底解决了的。

即：此处的cygwin，已经是，旧的3.81版本的了。不应该再出现此问题才对。

但是怎么此处又出现了。

2.去看了看，当前的make的版本：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ make --version
GNU Make 3.82.90
Built for i686-pc-cygwin
Copyright (C) 2010  Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

果然是异常的3.82.

3.然后才想起来，估计是之前：

【记录】将win7 x64下的cygwin的gcc从当前的4.7.3降级到4.5.3

不小心，结果cygwin安装过程，内部自动把3.81升级为3.82了。

4.所以，只能此处，再去重新，降级make，将当前的3.82，再次重新换为3.81的：

【记录】更换cygwin中某个模块的版本：再次将make从3.82换成3.81

5.然后再去编译试试，就可以了：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ make
>>>   Installing kernel headers

                INSTALL_HDR_PATH=/home/CLi/develop/buildroot/buildroot-2013.05/output/toolchain/linux headers_install; \
        )

如图：

【总结】

此处，cygwin下编译buildroot，又出现了之前就遇到的：

错误，原因是：

makefile的版本，3.81的时候，支持混合语法，3.82不支持，

当前是3.82的make。

解决办法是：

换成3.81的make。

相关的内容，详见：

Makefile:240: *** mixed implicit and normal rules. Stop.
