【记录】crosstool为xscale编译(ct-ng build)过程
期间，编译出错，完整log：

【解决过程】
1.去对应的log文件：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\x-tools\arm-xscale-linux-gnueabi\build.log
看看，最后的log是：
[ALL ] Overiding config.guess and config.sub [ALL ] `/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/config.guess' -> `./config.guess' [ALL ] `/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/config.guess' -> `./readline/support/config.guess' [ALL ] `/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/config.sub' -> `./config.sub' [ALL ] `/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/config.sub' -> `./readline/support/config.sub' [DEBUG] ==> Executing: 'touch /home/CLi/develop/crosstool-ng/crosstool-ng-1.9.3_build/targets/src/.gdb-6.8.patched' [DEBUG] ==> Executing: 'rm -f /home/CLi/develop/crosstool-ng/crosstool-ng-1.9.3_build/targets/src/.gdb-6.8.patching' [DEBUG] ==> Executing: 'touch /home/CLi/develop/crosstool-ng/crosstool-ng-1.9.3_build/targets/src/.ncurses-5.7.extracting' [EXTRA] Extracting 'ncurses-5.7' [DEBUG] ==> Executing: 'tar xvzf /home/CLi/develop/crosstool-ng/crosstool-ng-1.9.3_build/targets/tarballs/ncurses-5.7.tar.gz' [FILE ] [FILE ] gzip: stdin: unexpected end of file [FILE ] tar: Child returned status 1 [FILE ] tar: Error is not recoverable: exiting now [ERROR] Build failed in step 'Extracting and patching toolchain components' [ERROR] Error happened in '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' in function 'CT_DoExecLog' (line unknown, sorry) [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' at line # 681 in function 'CT_Extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug/300-gdb.sh' at line # 65 in function 'do_debug_gdb_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug.sh' at line # 28 in function 'do_debug_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/crosstool-NG.sh' at line # 569 in function 'main' [ERROR] Look at '/home/CLi/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/build.log' for more info on this error. [ERROR] (elapsed: 10:01.80)
看起来，错误还是和crosstool本身有关，而不是某个库。
2.参考：
说貌似是由于linux tarball有问题。
但是觉得有问题啊，因为前面已经：
[EXTRA] Extracting 'linux-2.6.36' [EXTRA] Patching 'linux-2.6.36'
了，并且可以看到解压后的linux-2.6.36文件夹和文件的。
3.突然发现，貌似是ncurses-5.7.tar.gz有问题，而导致
gzip: stdin: unexpected end of file
的，所以，重新去下载一个：
重新放到：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src
去，再重新编译试试，结果又有其他错误：
[email protected] ~/develop/crosstool-ng/crosstool-ng-1.9.3_build $ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130723.171055 [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 0.82s (at 00:33) [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [INFO ] Retrieving needed toolchain components' tarballs: done in 1.57s (at 00:35) [INFO ] ================================================================= [INFO ] Extracting and patching toolchain components [ERROR] The 'ncurses-5.7' sources were partially extracted.

[00:41] / /opt/crosstool-ng/bin/ct-ng:143: recipe for target `build' failed make: *** [build] Error 1
4.所以，先去删除：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src\.ncurses-5.7.extracting
再去重新build，结果又是开始的错误：
[email protected] ~/develop/crosstool-ng/crosstool-ng-1.9.3_build $ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130723.171353 [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 0.91s (at 00:34) [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [INFO ] Retrieving needed toolchain components' tarballs: done in 1.58s (at 00:36) [INFO ] ================================================================= [INFO ] Extracting and patching toolchain components [EXTRA] Extracting 'ncurses-5.7' [ERROR] Build failed in step 'Extracting and patching toolchain components' [ERROR] Error happened in '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' in function 'CT_DoExecLog' (line unknown, sorry) [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' at line # 681 in function 'CT_Extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug/300-gdb.sh' at line # 65 in function 'do_debug_gdb_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug.sh' at line # 28 in function 'do_debug_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/crosstool-NG.sh' at line # 569 in function 'main' [ERROR] Look at '/home/CLi/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/build.log' for more info on this error. [ERROR] (elapsed: 0:38.24) [00:42] / /opt/crosstool-ng/bin/ct-ng:143: recipe for target `build' failed make: *** [build] Error 2
然后看到log中内容是：
[DEBUG] ==> Executing: 'touch /home/CLi/develop/crosstool-ng/crosstool-ng-1.9.3_build/targets/src/.ncurses-5.7.extracting' [EXTRA] Extracting 'ncurses-5.7' [DEBUG] ==> Executing: 'tar xvzf /home/CLi/develop/crosstool-ng/crosstool-ng-1.9.3_build/targets/tarballs/ncurses-5.7.tar.gz' [FILE ] [FILE ] gzip: stdin: unexpected end of file [FILE ] tar: Child returned status 1 [FILE ] tar: Error is not recoverable: exiting now [ERROR] Build failed in step 'Extracting and patching toolchain components' [ERROR] Error happened in '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' in function 'CT_DoExecLog' (line unknown, sorry) [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' at line # 681 in function 'CT_Extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug/300-gdb.sh' at line # 65 in function 'do_debug_gdb_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug.sh' at line # 28 in function 'do_debug_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/crosstool-NG.sh' at line # 569 in function 'main' [ERROR] Look at '/home/CLi/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/build.log' for more info on this error. [ERROR] (elapsed: 0:38.24)
即，对于ncurses-5.7.tar.gz，用的是tar xvzf，所以看起来不对，应该是针对xx.tar.bz2才用xvzf
5.所以，重新去找个ncurses-5.7.tar.bz2，最后在：
http://code.google.com/p/mywolfe/source/browse/trunk/T2-8rc-N/ncurses-5.7.tar.bz2?r=118
找到：
http://mywolfe.googlecode.com/svn-history/r118/trunk/T2-8rc-N/ncurses-5.7.tar.bz2
下载后，拷贝到：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src
并且删除其下的：
ncurses-5.7.tar.gz
和
.ncurses-5.7.extracting
然后重新编译试试：
结果仍然出错：
[email protected] ~/develop/crosstool-ng/crosstool-ng-1.9.3_build $ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130723.171924 [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 0.88s (at 00:34) [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [INFO ] Retrieving needed toolchain components' tarballs: done in 1.60s (at 00:36) [INFO ] ================================================================= [INFO ] Extracting and patching toolchain components [EXTRA] Extracting 'ncurses-5.7' [ERROR] Build failed in step 'Extracting and patching toolchain components' [ERROR] Error happened in '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' in function 'CT_DoExecLog' (line unknown, sorry) [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' at line # 681 in function 'CT_Extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug/300-gdb.sh' at line # 65 in function 'do_debug_gdb_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug.sh' at line # 28 in function 'do_debug_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/crosstool-NG.sh' at line # 569 in function 'main' [ERROR] Look at '/home/CLi/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/build.log' for more info on this error. [ERROR] (elapsed: 0:38.28) [00:43] / /opt/crosstool-ng/bin/ct-ng:143: recipe for target `build' failed make: *** [build] Error 2
但是很诡异的是，log文件：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\x-tools\arm-xscale-linux-gnueabi\build.log
中的log内容，没有任何变化：
6.删除：
.ncurses-5.7.extracting
和
ncurses-5.7.tar.bz2
让其自己下载试试是否会出错。
7.不过，突然发现，原来这里：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\tarballs\ncurses-5.7.tar.gz
还有个ncurses-5.7.tar.gz，所以刚才才出问题，不是用我最新的ncurses-5.7.tar.bz2，所以，删除：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\tarballs\ncurses-5.7.tar.gz
再拷贝ncurses-5.7.tar.bz2到：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src
重新编译试试，然后貌似终于可以了：
[EXTRA] Extracting 'ncurses-5.7' [EXTRA] Patching 'ncurses-5.7'
8.但是接着又出现了同样的错误，但是是对于expat-2.0.1的：
[email protected] ~/develop/crosstool-ng/crosstool-ng-1.9.3_build $ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130723.172851 [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 0.91s (at 00:33) [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [INFO ] Retrieving needed toolchain components' tarballs: done in 1.85s (at 00:36) [INFO ] ================================================================= [INFO ] Extracting and patching toolchain components [EXTRA] Extracting 'ncurses-5.7' [EXTRA] Patching 'ncurses-5.7' [EXTRA] Extracting 'expat-2.0.1' [ERROR] Build failed in step 'Extracting and patching toolchain components' [ERROR] Error happened in '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' in function 'CT_DoExecLog' (line unknown, sorry) [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' at line # 681 in function 'CT_Extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug/300-gdb.sh' at line # 70 in function 'do_debug_gdb_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug.sh' at line # 28 in function 'do_debug_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/crosstool-NG.sh' at line # 569 in function 'main' [ERROR] Look at '/home/CLi/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/build.log' for more info on this error. [ERROR] (elapsed: 1:30.63) [01:35] / /opt/crosstool-ng/bin/ct-ng:143: recipe for target `build' failed make: *** [build] Error 2
然后去看了看：
（1）
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src
中，没有任何关于expat-2.0.1的tar包或类似的.expat-2.0.1.extracting的文件。
（2）D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\src
中的确有：expat-2.0.1.tar.gz
但是size是1KB：
很明显不是合法的tar包。
所以：
（1）先去删除：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\tarballs
中的
expat-2.0.1.tar.gz
（2）再去删除：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\src
中的：
expat-2.0.1.tar.gz
（3）重新下载一个完整的：
http://www.linuxfromscratch.org/blfs/view/6.3/general/expat.html
->
http://downloads.sourceforge.net/expat/expat-2.0.1.tar.gz
->
或：
http://zh.sourceforge.jp/projects/sfnet_expat/downloads/expat/2.0.1/expat-2.0.1.tar.gz/
->
得到436KB的：
expat-2.0.1.tar.gz
然后，拷贝到：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src
然后重新编译试试，结果还是错误：
[email protected] ~/develop/crosstool-ng/crosstool-ng-1.9.3_build $ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130723.174202 [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 00:34) [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [INFO ] Retrieving needed toolchain components' tarballs: done in 1.86s (at 00:36) [INFO ] ================================================================= [INFO ] Extracting and patching toolchain components [ERROR] The 'expat-2.0.1' sources were partially extracted.

[00:42] / /opt/crosstool-ng/bin/ct-ng:143: recipe for target `build' failed make: *** [build] Error 1
9.估计是要用expat-2.0.1.tar.bz2才可以。
所以去找，http://zh.sourceforge.jp/projects/sfnet_devkitpro/downloads/portlibs/src/expat-2.0.1.tar.bz2/
->
然后
（1）删除：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src
中的.expat-2.0.1.extracting和expat-2.0.1.tar.gz
（2）删除
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\tarballs
中的
expat-2.0.1.tar.gz
（3）拷贝刚下载的336KB的expat-2.0.1.tar.bz2到：
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\crosstool-ng\crosstool-ng-1.9.3_build\targets\src
然后再次编译试试，最后终于可以了：
[EXTRA] Extracting 'expat-2.0.1' [EXTRA] Patching 'expat-2.0.1'
【总结】
当编译crosstool时，出现类似于：
[EXTRA] Extracting 'ncurses-5.7' [ERROR] Build failed in step 'Extracting and patching toolchain components' [ERROR] Error happened in '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' in function 'CT_DoExecLog' (line unknown, sorry) [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/functions' at line # 681 in function 'CT_Extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug/300-gdb.sh' at line # 65 in function 'do_debug_gdb_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/build/debug.sh' at line # 28 in function 'do_debug_extract' [ERROR] called from '/opt/crosstool-ng/lib/ct-ng-1.9.3/scripts/crosstool-NG.sh' at line # 569 in function 'main' [ERROR] Look at '/home/CLi/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/build.log' for more info on this error.
的错误时，原因和解决办法是：
（以此处的ncurses-5.7为例）
1.对应的库文件是xxx.tar.gz
比如
ncurses-5.7
所对应的：
ncurses-5.7.tar.gz，所以出错。
解决办法：
换成ncurses-5.7.tar.bz2
2.用到的tar包，的确本身是有问题的
要么是，crosstool自动通过网络下载，结果中间出错，只下载了部分，没下载完全，所以gzip解压出错；
要么是，你自己下载的，然后拷贝过来的，结果不小心，也是下载了部分内容，tar包不完整，导致gzip解压出错。
解决办法：
删除旧的文件，比如ncurses-5.7.tar.bz2
重新下载一个，完整的。
注意：
不论哪种原因，都要注意的是，要去：
（1）删除：
crosstool-ng\crosstool-ng-1.9.3_build\targets\src
中的.ncurses-5.7.extracting和ncurses-5.7.tar.gz
（2）删除
crosstool-ng\crosstool-ng-1.9.3_build\targets\tarballs
中的
ncurses-5.7.tar.gz
（3）拷贝最新的
ncurses-5.7.tar.bz2
到：
crosstool-ng\crosstool-ng-1.9.3_build\targets\src
