Handbook Talk:IA64/Installation/Stage

These switches break the ia64 build
In 2016-09-xx, entering "-march=native" into file "make.conf" will build no files. This is because the IA64 version of gcc on Gentoo can only generate "ia64" code and so does not support the "-march" switch. This compiler does support the "-mtune" switch with values of "itanium1" and "itanium2" but this version of gcc defaults to "itanium2" so I suggest not modifying this file at all (at least not for the initial first few builds). Now if things don't build properly then I suggest using "-mtune=itanium1" which is were HP left their contribution to the Linux would things after they shifted transferred their collective attentions back to HP-UX. Similarly, I don't think it is wise during a first build to add MAKEOPTS to file "make.conf". Play around with these once you a more comfortable with the Gentoo build tools.
