[Boost-users] [boost] Minimum GCC required to support build

Hello, What is the minimum GCC I will need to compile boost? All of it if I can, or majority of it? And then what might I be giving up? Specifically, I am working with GCC 4.4.3 in Ubuntu LInux 10.04 LTS. I'd like to upgrade that to 4.7 if not 4.8 for C++11 features. I've read it can be done, but that makes me nervous upgrading such a crucial part of the Linux tool chain. Also, bearing in mind that we will need to cross compile to ARM5: I believe crosstool-ng might be the thing that enables that. Any insights would be appreciated. Thank you. Regards, Michael Powell
