【问题】
折腾：
【记录】cygwin下在针对arm920t去ct-ng menuconfig配置后去ct-ng build去编译
期间，编译出错：

晕死，貌似是内存不够用？
但是很奇怪，当前共6G内存，目前才用了3.8G，还有好多呢。
2.试试重新执行当前命令：
exit 2
看看效果：
结果问题依旧：

重新ct-ng build试试：
3.参考：
其办法是：
最后，我的解决的方法是，更换make.exe的运行兼容模式： “Run this program in compatibility mode for:” and choose “Windows XP （Service Pack 2 or |
但是，还是觉得奇怪：
之前另外一个cygwin中，都没有遇到这个问题。
4.不过，貌似或许的确是权限问题。但是不应该以这种办法解决才对。
另外参考：
说是要把cygwin的path路径设置为最小，而解决问题。
难道是：
路径中有空格等问题，导致此错误的？？？
5.对于上述解决办法，也在：
Re: Cygwin fork problem: abort: can’t commit memory for stack
中看到了。
且其是先是把path弄成只包含cygwin，就可以编译了。
而且是后来慢慢恢复到原先的path的值，结果也是可以编译了。
所以，还是很奇怪的，没找到根本原因。
6.后来看到：
make, PATH & "Win32 error 487"
大概看懂了意思：
fork一直不是100%成功的，和操作系统有关系；
从make fork出的第一个shell，和之后的subshell，基本没区别；
唯一区别就是：$PATH的值的size大小，影响到了forked的子进程，在主栈的位置
然后经过该人的修复，貌似此问题，已经解决了。
是放到了最新的http://cygwin.com/snapshots/中了。
7.所以，此处，去看看：
看到对应的：
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
然后，我此处的，虽然是x64的win7，但是之前是安装的x86的cygwin。
所以去下载对应的x86的cygwin的dll：
http://cygwin.com/snapshots/x86/cygwin1-20130830.dll.bz2
下载后，解压得到2.38M的
cygwin1-20130830.dll
然后，去把原先的：
2012/10/19的cygwin1.dll，重新改名，比如为cygwin1_dll_backup
再把cygwin1-20130830.dll改名为cygwin1.dll，放到对应位置：
然后，重新运行cygwin，确保正常可用：
然后就可以继续去编译试试了。
8.抽空再去ct-ng build，结果又出现另外的错误：
9.不过，去看了看对应的build.log，的确是解决问题了。

所以，至少是解决了此处的问题，没有出现之前的：
| 1 [main] sh 7800 child_info_fork::abort: can’t commit memory for stack 0x28A000(90112), Win32 error 487 |
的问题的。
【总结】
此处，cygwin下编译crosstool-ng，在：
Installing kernel headers
阶段，出现：
| [ERROR] make[4]: *** [/home/develop/crosstool-ng/x-tools/arm-arm920t-linux-gnueabi/arm-arm920t-linux-gnueabi/sysroot/usr/include/linux/.check] Error 254 |
对应的是错误时：
| 1 [main] sh 7800 child_info_fork::abort: can’t commit memory for stack 0x28A000(90112), Win32 error 487 |
其原因是：
cygwin本身有bug，导致fork会出错。
解决办法是：
把cygwin中/bin下面的那个cygwin1.dll，换成最新版本的即可。
最新版本的cygwin1.dll，可以去：
下载得到。
比如此刻，最新的是2013-08-30的，对应的地址是：
http://cygwin.com/snapshots/x86/cygwin1-20130830.dll.bz2
下载后，解压，改名为cygwin1.dll，替换掉旧的cygwin1.dll，就可以了。
