ubuntu下安裝ARM交叉編譯工具

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

將上面的地址加到我們的/etc/apt/sources.list下；

手動將 deb http://www.emdebian.org/debian/ stable main添加到 /etc/apt/sources.list 一般用戶的權限是不夠的，所以需要在你的 編輯器前加上sudo的呢。

2，千萬別忘了

sudo apt-get update

3.更新成功后

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

Ok,如果有什么問題，請跟貼聯系。

4，境在執行第二步的時候，遇到這樣的問題：

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
解決辦法：

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時，遇到了這樣的問題：

@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).
既然遇到了這個犯人的問題，那我們只好硬著頭皮去解決了,解決辦法：

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

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