Re: CPU specific binaries
I'm a sysadmin who also would be interested in recompiling to optimise for
specific CPUs. As far as I can make out, to do this I have to download
source and edit the debain/rules and/or Makefile of each package to pass the
appropriate optimisation flags to the compiler, then rebuild the package.
Then I have to deal with any errors I've introduced.
There has to be a better way of doing this. Am I missing something?
What is needed is a switch when invoking the build process or a configuration
file on the system somewhere that says "I'd like to optimise this package for
a 486/P5/K6/whatever". The package build process could (optionally) check for
this and pass all the appropriate optimisation options.
If something like this existed, I'd use it. It would also make it easy to
create 3'rd party optimised debian distros.
