From 23a0f8808ea86612c9b2ce48b65fcf8c0701c04a Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Thu, 6 Jul 2017 19:43:36 +0200 Subject: [PATCH] package/linuxptp: set KBUILD_OUTPUT to STAGING_DIR incdefs.sh try to define some flags with user_flags() and kernel_flags() functions. The later is looking at the kernel headers installed on the host when KBUILD_OUTPUT is not set. If no kernel headers are installed on the host, the grep fail and HAVE_ONESTEP_SYNC is not set on the command line: see: grep: /usr/include/linux/net_tstamp.h: No such file or directory So the missing.h define HWTSTAMP_TX_ONESTEP_SYNC which is also present in the kernel headers installed in STAGING_DIR (toolchain w/ headers >= 3.2). Indeed KBUILD_OUTPUT is empty because it's reset in the makefile, so move KBUILD_OUTPUT in the enviroment while calling "make"/ Also set KBUILD_OUTPUT to STAGING_DIR to find net_tstamp.h. While at it, use the same arguments for BUILD_CMDS and INSTALL_TARGET_CMDS. Thanks to Yann for the live review during the Buildroot summer camp.
