【背景】
折腾：
【记录】在Cygwin下编译gcc-3.4.5-glibc-2.3.6的arm-xscale-linux-gnu交叉编译器
期间，在配置好crosstool：
后，且也基本准备好源码包后，真正去开始编译。
【折腾过程】
1.然后再去真正开始编译ct-ng build，结果出错：
重启电脑。
2.然后的确可以编译了：
CLi@PC-CLI-1 ~/develop/crosstool-ng/crosstool-ng-1.9.3_build $ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130723.154847 [INFO ] Building environment variables [EXTRA] Preparing working directories [EXTRA] Installing user-supplied crosstool-NG configuration [EXTRA] ================================================================= [EXTRA] Dumping internal crosstool-NG configuration [EXTRA] Building a toolchain for: [EXTRA] build = i686-pc-cygwin [EXTRA] host = i686-pc-cygwin [EXTRA] target = arm-xscale-linux-gnueabi [EXTRA] Dumping internal crosstool-NG configuration: done in 0.90s (at 00:30) [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [EXTRA] Retrieving 'binutils-2.20' [02:11] /
很明显，在下载binutils的源码。但是，之前已经是把源码都下载好了，放到src下面了啊。
3. 后来才发现，原来是，此build，会自动生成对应的src文件夹的：
![build targets src empty_thumb[1]](https://www.crifan.com/files/pic/uploads/2013/07/build-targets-src-empty_thumb1_thumb.png "build targets src empty_thumb[1]")
所以，把上面的源码都拷贝到新生成的目录：
crosstool-ng\crosstool-ng-1.9.3_build\targets\src
中去。
4.但是突然发现，为何此处，用的binutils是2.20，而不是我之前看到的2.22的版本？？？
结果发现是自己上面下载错了。。。
重新去下载一个：
然后都拷贝到
crosstool-ng\crosstool-ng-1.9.3_build\targets\src
中：
5.然后重新中断编译，重新编译，貌似的确可以找到binutils-2.20了：

6.但是没有找到glibc-ports-2.9，所以，再去下载glibc-ports-2.9
结果其自己很快下载好了：
[EXTRA] Retrieving 'glibc-ports-2.9' [EXTRA] Saving 'glibc-ports-2.9.tar.bz2' to local storage
又去下载ncurses-5.7：
[EXTRA] Retrieving 'ncurses-5.7'
7.再去下载：
中断，重新build，然后貌似都下载好了，开始解压了：

8.然后编译出错了：
9.解决了上述问题后，就可以正常执行了：

10.但是结果是死在了Building GMP ：

10.然后后来去，中断掉，试试多线程：
ct-ng build.4
暂时看来，速度也没太大提升：

不过，的确看到，有多个进程了：
所以，估计对于后期更大的任务，会缩短时间吧。
11.最后，还是出错了：
