The fact that almost none of the OS > "devel" packages exist in 32-bit form suggests the latter. I for one have compiled Emacs in 32bit-mode on an amd64 machine in two difference circumstances: - once on my home machine which is a Debian GNU/Linux x86 system (no amd64 lib or compiler installed) with an amd64 kernel (mostly to get access to more than 3GB of ram, although a bigmem kernel would have done the trick as well). - once on my work machine, which is running a version of Fedora for amd64 and where some of the 32bit libs are indeed missing. There's still plenty of libs to build Emacs. The main reason there was to test the 32bit build, as well as to get a build which uses less memory. Stefan
