From e949f4c2d6a3df2b7fd00e56c0f081b15284906f Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 4 Jun 2019 19:13:59 +0900 Subject: kbuild: add CONFIG_HEADERS_INSTALL and loosen the dependency of samples Commit 5318321d367c ("samples: disable CONFIG_SAMPLES for UML") used a big hammer to fix the build errors under the samples/ directory. Only some samples actually include uapi headers from usr/include. Introduce CONFIG_HEADERS_INSTALL since 'depends on HEADERS_INSTALL' is clearer than 'depends on !UML'. If this option is enabled, uapi headers are installed before starting directory descending. I added 'depends on HEADERS_INSTALL' to per-sample CONFIG options. This allows UML to compile some samples. $ make ARCH=um allmodconfig samples/ [ snip ] CC [M] samples/configfs/configfs_sample.o CC [M] samples/kfifo/bytestream-example.o CC [M] samples/kfifo/dma-example.o CC [M] samples/kfifo/inttype-example.o CC [M] samples/kfifo/record-example.o CC [M] samples/kobject/kobject-example.o CC [M] samples/kobject/kset-example.o CC [M] samples/trace_events/trace-events-sample.o CC [M] samples/trace_printk/trace-printk.o AR samples/vfio-mdev/built-in.a AR samples/built-in.a Signed-off-by: Masahiro Yamada --- arch/arc/configs/tb10x_defconfig | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/arc') diff --git a/arch/arc/configs/tb10x_defconfig b/arch/arc/configs/tb10x_defconfig index 5b5119d2b5d5..dc739bd093e3 100644 --- a/arch/arc/configs/tb10x_defconfig +++ b/arch/arc/configs/tb10x_defconfig @@ -94,6 +94,7 @@ CONFIG_CONFIGFS_FS=y CONFIG_DEBUG_INFO=y CONFIG_STRIP_ASM_SYMS=y CONFIG_DEBUG_FS=y +CONFIG_HEADERS_INSTALL=y CONFIG_HEADERS_CHECK=y CONFIG_DEBUG_SECTION_MISMATCH=y CONFIG_MAGIC_SYSRQ=y -- cgit v1.2.3 From 75dd47472b92c320304436c9e38638bc04ae7a4a Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 6 Jul 2019 12:07:11 +0900 Subject: kbuild: remove src and obj from the top Makefile Replace $(src) and $(obj) with $(srctree) and $(objtree), respectively.
