"$(STAGING_DIR)/include" was carried over from buildroot-ng to OpenWrt in commit 60c1f0f64d23003a19a07d6b9638542130f6641d. buildroot has dropped this directory a long time ago.
In OpenWrt the directory is still created by the PrepareStaging macro and is part of the default TARGET_CPPFLAGS. But nothing at all installs headers into this directory, nor should anything be installed under this path. Removing this directory from TARGET_CPPFLAGS will cut down the log noise a bit. Not only will CPPFLAGS be shorter, there will be less warnings set off by "-Wmissing-include-dirs" (or even failures when paired with "-Werror"). After all the directory does not even _exist_ in the SDKs, which are used on the build bots when building packages (see [1] and [2]). make[8]: Entering directory '/builder/shared-workdir/build/sdk/build_dir/target-aarch64_generic_musl/libmbim-1.20.0/src/common' CC libmbim_common_la-mbim-common.lo cc1: error: /builder/shared-workdir/build/sdk/staging_dir/target-aarch64_generic_musl/include: No such file or directory [-Werror=missing-include-dirs] cc1: all warnings being treated as errors [1] https://github.com/openwrt/packages/issues/10377 [2] https://github.com/openwrt/packages/pull/10378 Signed-off-by: Sebastian Kemper <sebastian...@gmx.net> --- rules.mk | 2 +- tools/Makefile | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/rules.mk b/rules.mk index fbf42f725d..66ddea2883 100644 --- a/rules.mk +++ b/rules.mk @@ -174,7 +174,7 @@ TARGET_CFLAGS:=$(TARGET_OPTIMIZATION)$(if $(CONFIG_DEBUG), -g3) $(call qstrip,$( TARGET_CXXFLAGS = $(TARGET_CFLAGS) TARGET_ASFLAGS_DEFAULT = $(TARGET_CFLAGS) TARGET_ASFLAGS = $(TARGET_ASFLAGS_DEFAULT) -TARGET_CPPFLAGS:=-I$(STAGING_DIR)/usr/include -I$(STAGING_DIR)/include +TARGET_CPPFLAGS:=-I$(STAGING_DIR)/usr/include TARGET_LDFLAGS:=-L$(STAGING_DIR)/usr/lib -L$(STAGING_DIR)/lib ifneq ($(CONFIG_EXTERNAL_TOOLCHAIN),) LIBGCC_S_PATH=$(realpath $(wildcard $(call qstrip,$(CONFIG_LIBGCC_ROOT_DIR))/$(call qstrip,$(CONFIG_LIBGCC_FILE_SPEC)))) diff --git a/tools/Makefile b/tools/Makefile index 23671cba91..2f57d25525 100644 --- a/tools/Makefile +++ b/tools/Makefile @@ -123,7 +123,7 @@ define PrepareStaging $(if $(QUIET),,set -x;) \ mkdir -p "$$dir"; \ cd "$$dir"; \ - mkdir -p bin lib include stamp; \ + mkdir -p bin lib stamp; \ ); done endef -- 2.23.0 _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
