Subject: [Patch] Fix IA64 compilation with separate build tree.
Date: Mon, 03 Nov 2003 23:59:07 +0000 [thread overview]
Message-ID: <marc-linux-ia64-106790402625772@msgid-missing> (raw)
Hi David,
The appended patch (as we discussed before) is necessary to allow
separate source and build trees for IA64. Without it, offsets.h
cannot be built if you do, say,
make O=../build/linux-2.5-ia64
and the gas checks never succeed.
