打算封裝一個整合Android開發環境的Ubuntu 12.04的LiveCD.在安裝Android原始碼環境的時候遇到了其他人一樣的問題, libgl1-mesa-glx:i386 裝不上.我用的是12.04.2的iso.下面是安裝資訊:

Do you want to continue [Y/n]? 

        當我們安裝libgl1-mesa-glx:i386的時候,他提示依賴 libgl1-mesa-dri:i386, 那我們就先裝這個 libgl1-mesa-dri:i386.等等.這裡先彆著急,看看REMOVED選項,他要把帶quantal的對應包全部解除安裝? 看到quantal我就想到了quantal核心,12.10已經使用改核心,而ubuntu 12.04.2之後的iso(好像12.04.2的有兩個映象,前期的一個是沒升級到 quantal核心的)映象也升級到這個核心了.這個核心的很多包有個特點,都是加quantal字尾的.如果看過Ubunt 12.04核心升級到3.5.0-23的文章就會有所瞭解.

How can I upgrade the Ubuntu 12.04.2 kernel to 3.5.0-23?         既然知道了這些,那說明我們要安裝的並不是 libgl1-mesa-glx:i386,而是要安裝對應的quantal版本,查了下,對應的名字是:libgl1-mesa-glx-lts-quantal:i386.         然後看看/usr/lib32/mesa/libGL.so.1是否存在,存在說明已經安裝好了,按照Android官方說明,加一個軟連結就行了:

sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so
