The preferred way is to make them options.That's what I'm trying to do, to make SCons figure out weather or not each machine has SSE/MMX support by using the output of some variable (hopefully with sysctl).What Geert tried to tell you was that this is not desired. Please use the option framework and e.g. --enable-sse or whatever it is and don't force any *compile time* detection. For example I'm building packages on a P4-Xeon, they should also run on a Pentium MMX.
Maybe the question was how to use sysctl(3) to detect it at
runtime?
