From mboxrd@z Thu Jan 1 00:00:00 1970 From: alex.bennee@linaro.org (=?UTF-8?q?Alex=20Benn=C3=A9e?=) Date: Thu, 6 Apr 2017 20:07:26 +0100 Subject: [RFC kvm-unit-tests PATCH 7/8] Makefiles: fix up the x86 build include and link paths In-Reply-To: <20170406190727.5624-1-alex.bennee@linaro.org> References: <20170406190727.5624-1-alex.bennee@linaro.org> Message-ID: <20170406190727.5624-8-alex.bennee@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org We still need to tell the compiler the correct search path for finding headers and the like. This is slightly complicated by the "dynamic" asm search path which is in our build tree but (may be) symlinked to the right architectures headers. Also we explicitly include SRCDIR for the linking scripts as VPATH doesn't seem to find them well enough.
