建立arm-linux交叉工具链 crosstool-ng

建立arm-linux交叉工具链 crosstool-ng

测试环境：ubuntu 10.4，10.10，11.4，11.10均无压力。

最近被这个arm-linux交叉编译器搞了5天，都快被崩溃了。终于成功了，好开心，于是再做一遍，没问题，在这里记录以下流程：

1.确定好自己机子于开发板
tool：crosstool-ng1.93
host：ubuntu 10.04.3.LTS
target：S3Carm9
（前3天我一直用fedora来安装，最后真的不行了，于是换成ubutu，现在知道编译过程与主机上的GCC版本和GDB版本以及BINUTILS版本其实是没有关系的。它提示你ld is too old ，是因为你下载的工具的版本不对，清自己核对自己下载的版本跟下面提到的vim .config里面的规定。）

2.
$sudo passwd -l (设置root密码
set the unix password:
reset the unix password:
scuess!
（切换到root用户下，安装相关工具。以下所有操作都在root用户下，以后编译前请su -l ，切换到root下面才编译）

3.下载这些工具包，通常有error的时候，很多是因为下面安装包不完全，如果下面安装包有找不到的，那么可能你的ubutu版本对不上，或者你的ubutu版本出现了点小错误（我有一天晚上就是因为cvsd找不到，然后不管了，照样安装，导致10多分钟后才提示gcc编译不过，然后从新下载）
apt-get install bison flex texinfo automake libtool cvs patch

apt-get install libncurses5*

apt-get install aria2 curl gcj g++ subversion  cvsd gawk

apt-get install glibc*

4.下载安装用到的工具包：（请千万要下完整！特别是那个gcc，我之前的gcc原来下了一半然后中断了，只有26M，就直接拿来用了，一直找不到问题所在，后来多次查看log，才知道原来一直是gcc编译错误，于是从新下载gcc）

binutils-2.19.1.tar.bz2    |    dmalloc-5.5.2.tgz

duma_2_5_15.tar.gz    |    expat-2.0.1.tar.gz

gcc-4.3.2.tar.bz2    |    gdb-6.8.tar.bz2

glibc-2.9.tar.bz2    |     glibc-ports-2.9.tar.bz2

gmp-4.3.2.tar.bz2    |     libelf-0.8.13.tar.gz

linux-2.6.33.7.tar.bz2    |     mpfr-2.4.2.tar.bz2

ncurses-5.7.tar.gz    |     Sstrip.c

strace-4.5.19.tar.bz2

一定要全部下载好，要不然以后的编译过程中，速度很慢还存在潜在的危险，说不定哪个包自动下载不下来，编译错误，那连原因也找不到。（我就试过这样）

5.处理一个小问题，具体我也不清楚。见大神网站：
http://hi.baidu.com/caicry/blog/item/f306db639c4281680c33fa1b.html
cd  /usr/bin

mv mawk mawk.bak

ln -s gawk mawk

cd /home

6.安装crosstool-ng，安装完之后 ct【tab】【tab】后会出现ct-ng，那么你安装成功了！恭喜第一步过了！

mkdir crosstool-ng

cd crosstool-ng

mkdir src
mv /（下载工具包的目录）  /home/crossrool-ng/src 这里千万不要变成/home/crossrool-ng/src/ (将上面下载的源码工具包全部复制到 src目录的下)

tar -jzvf crosstool-ng-1.9.3.tar.bz2

cd crosstool-ng-1.9.3

./configure --prefix=/opt/crosstool-ng

make

make install

make clean
echo "PATH=$PATH:/opt/crosstool-ng/bin" >> ~/.bashrc
source ~/.bashrc
打开一个terminal：
$ echo "PATH=$PATH:/opt/crosstool-ng/bin" >> ~/.bashrc  为后面调用ct-ng命令增加环境变量，让当前用户和超级用户都拥有权限
$ source ~/.bashrc下班了，明天继续写。

7.更改编译事项：

cd /home/crosstool-ng

mkdir  crosstool-ng-1.9.3_build  编译时的输出目录

cd crosstool-ng-1.9.3_build/

cp /opt/crosstool-ng/lib/ct-ng-1.9.3/samples/arm-unknown-linux-gnueabi/crosstool.config .config

 ct-ng menuconfig   一定要在上面建立的crosstool-ng-1.9.3_build目录下运行

改写下面的路径，按照上面的定义，最后的结果如下

Paths and misc options  --->

  (/home/crosstool-ng/src) Local tarballs directory           保存源码包路径

  (/opt/crosstool-ng/${CT_TARGET}) Prefix directory  交叉编译器的安装路径

 Target options  --->

           *** Target optimisations ***

           (armv4t) Architecture level

           (arm9tdmi) Emit assembly for CPU   

           (arm920t) Tune for CPU

C compiler --->

*** Additional supported languages:***

取消下面两个语言的选择

[*] C++

[ ] Fortran

[ ] Java

Paths and misc options  --->

   *** Build behavior ***

  (4) Number of parallel jobs 

如果是双核的话，不是在虚拟机下运行的，就填4.在虚拟机下，开2就行了，开4也没用。弄不好整死机了

保存退出，按enter，我按了个Y键，发觉编译出错，然后从新 ct-ng menuconfig，发觉刚才的都没有保存

8.不过还是建议检查一下你下载的linuxKERNEL版本于crosstool-ng初始化的版本是否一致：

vim .config

/KERNEL

不一致则修改修改

    CT_KERNEL_VERSION=2.6.32.17

    CT_KERNEL_V_2_6_32_17=y

    CT_LIBC_GLIBC_MIN_KERNEL=2.6.32.17

:wq保存退出

9.开始编译

.ct-ng build.4（bulid后面有个点，不要忘了。意思为4线程编译。一切正确配置的话，那么要等上30分钟或者1个小时）

这里要注意一下的就是，我一开始在fedora下面看到Extracting 'linux-2.6.33.7'好久，然后就ctrl+d中断程序了，后来才知道，自己设置的src地址错误，然后系统自动下载，让系统自动下载的慢的不行，而且前面显示的时间对不上，以为自己编译错误，然后在那里搞了很久。其实如果这里你src地址没有错，那么前面的时间基本上于系统时间匹配，而且很快一串这样的：

[INFO ]  Extracting and patching toolchain components
[EXTRA]    Extracting 'linux-2.6.33.7'
[EXTRA]    Patching 'linux-2.6.33.7'

[EXTRA]    Patching 'ltrace-0.5.3'
[EXTRA]    Extracting 'strace-4.5.19'

[EXTRA]    Patching 'strace-4.5.19'

10.最后设置默认路径，方便以后编译的时候不用从新安排路径：

echo "PATH=$PATH:/opt/crosstool-ng/arm-unknown-linux-gnueabi/bin" >> ~/.bashrc             //root家目录下的.bashrc

source ~/.bashrc立即生效

arm[tab][tab]之后，你会发现好多

arm-unknown-linux-gnueabi-addr2line
arm-unknown-linux-gnueabi-ar
arm-unknown-linux-gnueabi-as
arm-unknown-linux-gnueabi-c++
arm-unknown-linux-gnueabi-cc
arm-unknown-linux-gnueabi-c++filt

11.恭喜你，你交叉工具链制作成功了。好开心阿。搞了我5天了。一直被一些小小的问题卡主。如果还是不行的童鞋们，请不要着急与放弃。出错的原因有以下几大类：

001：apt-get install 的软件包安装不完整（如果还是安装不了我上面的包，请从新安装你的ubutu，我之前又一次因为ubutu安装不全，直接编译，error）

002：你下载的工具包错误或者版本不对（请仔细核对你的工具包与版本，记得看一下vim .config，地址上面有）

003：在编译的时候，会出现[EXTRA]    Extracting 'linux-2.6.33.7'，然后很久不动（那么你的src地址错误，请退出，从新检查ct-ng menuconfig）

004：有时候发觉自己没错，但是编译不过，那么请你删除/home/crosstool-ng/ /opt/crosstool-ng/，然后从新在编译一遍，很有可能你的地址或者其他分配错误，或者命令行打错了，我自己就曾经试过几遍。

12.最后一步个人认为比较重要，把系统备份起来咯。详细请参考我的另外一篇文章

最后附上我的成功编译过程：（如果你跟我有很大差别，那么很可能你错了，除了顺序）
