#Make is actually an interactive configuration step.
#The configuration is highly sensitive to your specific machine.
#Although it is quite good, it will default to accuracy over speed.
#Powertweakers might want to configure interactively (also for cross-compile)
# by uncommenting the next line and commenting the yes ""| make || die line .
# make || die
#atlas will automatically do a parallel make if possible.
yes "" | make || die
#Let's go grab the architecture determined by the configure
cd ${S}/bin
#There might be a better way to do this!?!
#We can assume "Linux" for a Gentoo Linux system.
#Need ATLAS_ARCH in src_install too.
ATLAS_ARCH=$(ls -d Linux*)
cd ${S}
#This doesn't install into the live / file system.
#It installs into ${S}/lib/Linux*
