[opensource-dev] Not actually OT: How do I get/update gcc to 4.6 on debian squeeze?
Hi gang, How do I upgrade gcc to 4.6 on debian squeeze? And what else does need to be upgraded on debian squeeze to have the versions that LL uses? The wiki page about setting up a build environment on linux still talks about gcc 4.3...

Hi, So how do I get gcc 4.6 on debian squeeze? Building the whole gcc toolchain from source? Cheers LC Am Dienstag, 19.

I don't know Debian distros well enough, but I suppose that their packaging system got the equivalent of rpm-based ones and allow you to grab a source package from a newer or older Debian version and recompile it under your installed version... So yes, you'd have to rebuild gcc and ancillary programs (cpp, g++, etc) and libraries (especially libstdc++), that should normally be packaged together. Note that if you are running a *newer* version of Debian (which should be the case if you have got gcc 4.7+ installed on your system), then you may even grab the binaries from the older Debian versions and install them on your system: since your glibc library will be newer than the one the older gcc was built against, the old binaries will run just fine on your system. However, note that distros usually make a distinction between the "system compiler" (the one used to build all the packages, and especially the kernel and modules for your distro version) and other (often older) compilers (sometimes required to be able to build antiquated software): you shall not overwrite your system compiler with another one when installing the latter... Rpm-based distros use different binary names for all compilers (for example: /usr/bin/gcc4.6 instead of just /usr/bin/gcc) and use "alternative" links (have a look at /etc/alternatives) to link the various compiler versions to a soft link (/usr/bin/gcc); an "update-alternatives" command is available to automatically update all the links (links to gcc, g++, cpp, libstdc++, etc must also be updated together) automatically, allowing you to easily switch from one version to another.
