Hello,<br><br>I am running GCC 4.4.3 (default?) distributed with Ubuntu Linux 10.04 LTS. I would like to build the latest Boost to keep up with the language and library standards, because we&#39;ll need those on a project we&#39;re working on (obviously), but it seems that we&#39;ll need to upgrade the GCC tool chain in order to do this: plus it us necessary even helpful to have access to lambda functors, expressions, etc, access Boost Phoenix (for Spirit2), and so on. I&#39;ve read how it&#39;s possible to upgrade the GCC tool chain, but it worries me for obvious reasons.<br>
<br>Also, building is one thing, the front end tool chain. We&#39;ll be cross compiling to ArchLinux running on ARM. I&#39;ve done some reading about this issue and it seems that this is more of a back end concern. In other words, as long as the thing builds, compiles and links with whatever tool chain, language standard, compiler, etc, the cross compile should go well. Specifically, I believe we&#39;re going with CodeBench, but if there are other cross compilers available, that would be helpful to know as well.<br>
<br>Any wisdom approaching an issue like this?<br><br>Regards,<br><br>Michael<br>
