From mboxrd@z Thu Jan 1 00:00:00 1970 From: Markos Chandras Subject: [PATCH] Documentation: ptp: Fix build failure on MIPS cross builds Date: Mon, 20 Oct 2014 09:42:18 +0100 Message-ID: <1413794538-28465-1-git-send-email-markos.chandras@imgtec.com> Mime-Version: 1.0 Content-Type: text/plain Cc: Markos Chandras , Richard Cochran , Jonathan Corbet , , , To: Return-path: Sender: linux-doc-owner@vger.kernel.org List-Id: netdev.vger.kernel.org The MIPS system calls are defined based on the -mabi gcc option. However, the testptp is built on the host using the unistd header from the kernel sources which were built for the MIPS architecture thus guarded with the __MIPS_SIM_{ABI64, ABI32, NABI32} definitions leading to the following build problem: Documentation/ptp/testptp.c: In function 'clock_adjtime': Documentation/ptp/testptp.c:55: error: '__NR_clock_adjtime' undeclared (first use in this function) Documentation/ptp/testptp.c:55: error: (Each undeclared identifier is reported only once Documentation/ptp/testptp.c:55: error: for each function it appears in.) This fix is similar to e9107f88c985bcda ("samples/seccomp/Makefile: do not build tests if cross-compiling for MIPS") Cc: Richard Cochran Cc: Jonathan Corbet Cc: netdev@vger.kernel.org Cc: linux-doc@vger.kernel.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Markos Chandras --- Documentation/ptp/Makefile | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/Documentation/ptp/Makefile b/Documentation/ptp/Makefile index 293d6c09a11f..397c1cd2eda7 100644 --- a/Documentation/ptp/Makefile +++ b/Documentation/ptp/Makefile @@ -1,5 +1,15 @@ # List of programs to build +ifndef CROSS_COMPILE hostprogs-y := testptp +else +# MIPS system calls are defined based on the -mabi that is passed +# to the toolchain which may or may not be a valid option +# for the host toolchain.
