The flags correspond to output from /proc/cpuinfo (the "flags" field). Like on my Celeron laptop I have: %cat /proc/cpuinfo | grep flags flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 pn mmx fxsr > 3) We've already had a brief discussion about this, but to fill you > in, the major two alternatives are to either have several package > binaries for each sub-arch, or to have all libs in one binary > package.

For libc6 I use seperate packages, but that is mainly because I don't want to force everyone to install all of these libs (since everyone has to have libc6 whether they want it or not :) The downside to seperate packages, is the increase in the Packages file, and the number of available packages in the dist. > 4) Most importantly, it appears that atlas cannot cross-compile, > i.e. the compiled code must *run* on the compilation machine.

There should be a way to compile for a CPU, without actually having that CPU. You will most likely have to hack the atlas build process to get this done. -- -----------=======-=-======-=========-----------=====------------=-=------ / Ben Collins -- ...on that fantastic voyage... -- Debian GNU/Linux \ ` [EMAIL PROTECTED] -- [EMAIL PROTECTED] -- [EMAIL PROTECTED] ' `---=========------=======-------------=-=-----=-===-======-------=--=---'
