ubuntu下安装ARM交叉编译工具

1，添加一个源到我们的/etc/apt/sources.list下，这样我么才可以sudo apt-get install gcc-armxxx；

源地址：deb http://www.emdebian.org/debian/ stable main

将上面的地址加到我们的/etc/apt/sources.list下；

手动将 deb http://www.emdebian.org/debian/ stable main添加到 /etc/apt/sources.list 一般用户的权限是不够的，所以需要在你的 编辑器前加上sudo的呢。

2，千万别忘了

sudo apt-get update

3.更新成功后

sudo apt-get install gcc-4.4-arm-linux-gnueabi

Ok,如果有什么问题，请跟贴联系。

4，境在执行第二步的时候，遇到这样的问题：

sudo apt-get update

W: GPG error: http://www.emdebian.org stable Release: The following signatures couldnt be verified because the public key is not available: NO_PUBKEY B5B7720097BB3B58
解决办法：

sudo apt-get install emdebian-archive-keyring

sudo apt-get update

答疑：

有人在sudo apt-get install gcc-4.4-arm-linux-gnueabi时，遇到了这样的问题：

@ubuntu:~$sudo apt-get install gcc-4.3-arm-linux-gnueabi
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run `apt-get -f install to correct these:
The following packages have unmet dependencies:
gcc-4.3-arm-linux-gnueabi: Depends: gcc-4.3-arm-linux-gnueabi-base (= 4.3.5-4) but it is not going to be installed
Depends: cpp-4.3-arm-linux-gnueabi (= 4.3.5-4) but it is not going to be installed
Depends: binutils-arm-linux-gnueabi (>= 2.19.1) but it is not going to be installed
Recommends: libc6-dev-armel-cross (>= 2.5) but it is not going to be installed
libmpfr4: Depends: libgmp10 but it is not installable
E: Unmet dependencies. Try apt-get -f install with no packages (or specify a solution).
既然遇到了这个犯人的问题，那我们只好硬着头皮去解决了,解决办法：

@ubuntu:~$sudo apt-get install libc6-dev-armel-cross

@ubuntu:~$sudo apt-get install binutils-arm-linux-gnueabi

安装libmpfr4，下载地址：http://www.anheng.com.cn/debian/pool/main/m/mpfr4/libmpfr4_3.0.0-9_i386.deb

@ubuntu:~$sudo dpkg -ilibmpfr4_3.0.0-9_i386.deb

@ubuntu:~$sudo apt-get install cpp-4.3-arm-linux-gnueabi

安装libgmp10，下载地址：http://www.anheng.com.cn/debian/pool/main/g/gmp/libgmp10_5.0.1+dfsg-7_i386.deb

@ubuntu:~$sudo dpkg -ilibgmp10_5.0.1+dfsg-7_i386.deb

@ubuntu:~$sudo apt-get install gcc-4.3-arm-linux-gnueabi-base

@ubuntu:~$sudo apt-get install gcc-4.4-arm-linux-gnueabi

搞定……
