折腾：
【记录】Ubuntu下用crosstool-ng为xscale建立交叉编译器arm-xscale-linux-gnueabi-gcc
期间，编译出错：

【解决过程】
1.很明显，是缺少了g++。
2.参考：
Ubuntu10.10下利用crosstool-ng构建交叉编译链
去安装g++：
crifan@ubuntu:~/develop/crosstool-ng/src$ sudo apt-get install g++ Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: g++-4.7 libstdc++6-4.7-dev Suggested packages: g++-multilib g++-4.7-multilib gcc-4.7-doc libstdc++6-4.7-dbg libstdc++6-4.7-doc The following NEW packages will be installed: g++ g++-4.7 libstdc++6-4.7-dev 0 upgraded, 3 newly installed, 0 to remove and 202 not upgraded.

3.再去继续编译，就可以了：
crifan@ubuntu:~/develop/crosstool-ng/crosstool-ng-1.18.0_build$ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130807.235739 [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-linux-gnu [EXTRA] host = i686-pc-linux-gnu [EXTRA] target = arm-xscale-linux-gnueabi [EXTRA] Dumping internal crosstool-NG configuration: done in 0.09s (at 00:02) [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [EXTRA] Using 'linux-custom' from custom location [INFO ] Retrieving needed toolchain components' tarballs: done in 0.30s (at 00:02) [INFO ] =================================================================
【总结】
当出现：
| [ERROR] Missing: ‘i686-pc-linux-gnu-g++’ or ‘i686-pc-linux-gnu-g++’ or ‘g++’ : either needed! |
时，原因是：
缺少了g++ -> Ubuntu默认情况下，没有安装这些工具
解决办法是：
其实也是可以去安装那个build-essential的。但是此处还是简单点，去只安装g++即可：
sudo apt-get install g++
