【背景】
之前，已经在另外一个win7上，基于cygwin，弄出了for xscale的arm-xscale-linux-gnueabi的交叉编译器：
【记录】重试使用最新版本1.18.0的crosstool-ng去配置和编译xscale的交叉编译器
并且，也在该win7下，VMWare中的Ubuntu下，弄了该for xscale的arm-xscale-linux-gnueabi的交叉编译器：
【记录】Ubuntu下用crosstool-ng为xscale建立交叉编译器arm-xscale-linux-gnueabi-gcc
此处，打算，在K470的win7 x64，6G内存+SSD下，在当前的cygwin下：
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0 $ cygpath.exe --version cygpath (cygwin) 1.7.17 Path Conversion Utility Copyright (C) 1998 - 2012 Red Hat, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
去再去弄个，for arm的，即针对TQ2440用的S3C2440的arm920t，弄个交叉编译器。
【折腾过程】
1.下载最新的源码：
Administrator@PC-20130611GART /home/develop/crosstool-ng $ wget http://crosstool-ng.org/download/crosstool-ng/crosstool-ng-1.18.0.tar.bz2 --2013-08-24 16:46:23-- http://crosstool-ng.org/download/crosstool-ng/crosstool-ng-1.18.0.tar.bz2 Resolving crosstool-ng.org (crosstool-ng.org)... 140.211.15.107 Connecting to crosstool-ng.org (crosstool-ng.org)|140.211.15.107|:80... connected.

2.继续参考，之前自己的：
【记录】重试使用最新版本1.18.0的crosstool-ng去配置和编译xscale的交叉编译器
【记录】Ubuntu下用crosstool-ng为xscale建立交叉编译器arm-xscale-linux-gnueabi-gcc
去折腾，先要把crosstool-ng安装到当前的cygwin中：
【记录】Cygwin下配置编译和安装crosstool-ng
3.然后，就可以接着去把对应的路径，加到PATH中：
修改.bashrc文件：
home\Administrator\.bashrc
期间竟然出错：
【已解决】Win7中用Notepad++编辑cygwin下面的文件结果保存出错：请检查文件是否在别的程序中打开
解决后，再去在.bashrc最后添加上：
PATH=$PATH:/opt/crosstool-ng/bin
然后再重新启动cygwin，就可以找到ct-ng了：
Administrator@PC-20130611GART /home/develop/crosstool-ng
$ which ct-ng
/opt/crosstool-ng/bin/ct-ng
Administrator@PC-20130611GART /home/develop/crosstool-ng
$ ct-ng --help
Usage: make [options] [target] ...
Options:
-b, -m Ignored for compatibility.
-B, --always-make Unconditionally make all targets.
-C DIRECTORY, --directory=DIRECTORY
Change to DIRECTORY before doing anything.
-d Print lots of debugging information.
--debug[=FLAGS] Print various types of debugging information.
-e, --environment-overrides
Environment variables override makefiles.
--eval=STRING Evaluate STRING as a makefile statement.
-f FILE, --file=FILE, --makefile=FILE
Read FILE as a makefile.
-h, --help Print this message and exit.
-i, --ignore-errors Ignore errors from recipes.
-I DIRECTORY, --include-dir=DIRECTORY
Search DIRECTORY for included makefiles.
-j [N], --jobs[=N] Allow N jobs at once; infinite jobs with no arg.
-k, --keep-going Keep going when some targets can't be made.
-l [N], --load-average[=N], --max-load[=N]
Don't start multiple jobs unless load is below N.
-L, --check-symlink-times Use the latest mtime between symlinks and target.
-n, --just-print, --dry-run, --recon
Don't actually run any recipe; just print them.
-o FILE, --old-file=FILE, --assume-old=FILE
Consider FILE to be very old and don't remake it.
-p, --print-data-base Print make's internal database.
-q, --question Run no recipe; exit status says if up to date.
-r, --no-builtin-rules Disable the built-in implicit rules.
-R, --no-builtin-variables Disable the built-in variable settings.
-s, --silent, --quiet Don't echo recipes.
-S, --no-keep-going, --stop
Turns off -k.
-t, --touch Touch targets instead of remaking them.
--trace Print tracing information.
-v, --version Print the version number of make and exit.
-w, --print-directory Print the current directory.
--no-print-directory Turn off -w, even if it was turned on implicitly.
-W FILE, --what-if=FILE, --new-file=FILE, --assume-new=FILE
Consider FILE to be infinitely new.
--warn-undefined-variables Warn when an undefined variable is referenced.

$4.再去创建对应的build文件夹，以及列表看看sample：
Administrator@PC-20130611GART /home/develop/crosstool-ng $ mkdir crosstool-ng-1.18.0_build Administrator@PC-20130611GART /home/develop/crosstool-ng $ ls crosstool-ng-1.18.0 crosstool-ng-1.18.0.tar.bz2 crosstool-ng-1.18.0_build src Administrator@PC-20130611GART /home/develop/crosstool-ng $ cd crosstool-ng-1.18.0_build/ Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0_build $ ls Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0_build $ ct-ng list-samples Status Sample name LN config MKDIR config.gen IN config.gen/arch.in IN config.gen/kernel.in IN config.gen/cc.in IN config.gen/binutils.in IN config.gen/libc.in IN config.gen/debug.in [G.X] alphaev56-unknown-linux-gnu [G.X] alphaev67-unknown-linux-gnu [G.X] arm-bare_newlib_cortex_m3_nommu-eabi [G.X] arm-cortex_a15-linux-gnueabi [G..] arm-cortex_a8-linux-gnueabi [G..] arm-davinci-linux-gnueabi [G..] arm-unknown-eabi [G..] arm-unknown-linux-gnueabi [G.X] arm-unknown-linux-uclibcgnueabi [G..] armeb-unknown-eabi [G.X] armeb-unknown-linux-gnueabi [G.X] armeb-unknown-linux-uclibcgnueabi [G.X] armv6-rpi-linux-gnueabi [G.X] avr32-unknown-none [G..] bfin-unknown-linux-uclibc [G..] i586-geode-linux-uclibc [G.X] i586-mingw32msvc,i686-none-linux-gnu [G.X] i686-nptl-linux-gnu [G.X] i686-unknown-mingw32 [G.X] m68k-unknown-elf [G.X] m68k-unknown-uclinux-uclibc [G.X] mips-ar2315-linux-gnu [G.X] mips-malta-linux-gnu [G..] mips-unknown-elf [G.X] mips-unknown-linux-uclibc [G.X] mips64el-n32-linux-uclibc [G.X] mips64el-n64-linux-uclibc [G..] mipsel-sde-elf [G..] mipsel-unknown-linux-gnu [G..] powerpc-405-linux-gnu [G..] powerpc-860-linux-gnu [G.X] powerpc-e300c3-linux-gnu [G.X] powerpc-e500v2-linux-gnuspe [G..] powerpc-unknown-linux-gnu [G..] powerpc-unknown-linux-uclibc [G..] powerpc-unknown_nofpu-linux-gnu [G.X] powerpc64-unknown-linux-gnu [G.X] s390-ibm-linux-gnu [G.X] s390x-ibm-linux-gnu [G..] sh4-unknown-linux-gnu [G..] x86_64-unknown-linux-gnu [G..] x86_64-unknown-linux-uclibc [G.X] x86_64-unknown-mingw32 L (Local) : sample was found in current directory G (Global) : sample was installed with crosstool-NG X (EXPERIMENTAL): sample may use EXPERIMENTAL features B (BROKEN) : sample is currently broken Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0_build $
5.然后接着就是去折腾for arm的交叉编译器了：
【记录】Cygwin下安装crosstool-ng后去为arm920t制作交叉编译器
6.
【总结】
