First, I was having problems with self-kang CyanogenMod 9 builds on my Samsung Tab 7 Plus (specifically, adb wouldn’t work). Second, I couldn’t boot Linux kernel 3.3 on my Sandy Bridge Core i7-2600 build server. I didn’t know the problems were because of GCC until recently, but now that I’ve switched back to 4.4 both of those problems have gone away; I can only assume that something in Ubuntu’s GCC fork is broken. The solution: set GCC 4.4 as the default compiler. It’s pretty easy to do this in Debian-based distros using the alternatives system. Install GCC 4.4 First, install GCC 4.4 (and friends): apt-get install gcc-4.4 g-4.4 g-4.4-multilib gcc-4.4-multilib Set 4.4 to be the default Then set 4.4 to be higher priority than 4.6: update-alternatives --install /usr/bin/g g /usr/bin/g-4.4 100
update-alternatives --install /usr/bin/g g /usr/bin/g-4.6 50
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 100
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 50
update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-4.4 100
update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-4.6 50 Verify that it has worked: gcc -v
Using built-in specs.
