I was not aware of the internal variable. What I discovered so far: ``` txt@txt:/media/ssd/lede$ grep --no-message -R HOSTCPPFLAGS ./ ./include/u-boot.mk: HOSTCFLAGS='$(HOST_CFLAGS) $$$$(HOSTCPPFLAGS)' \ txt@txt:/media/ssd/lede$ grep --no-message -R HOST_CPPFLAGS ./ ./package/devel/strace/Makefile: CPPFLAGS_FOR_BUILD="$(HOST_CPPFLAGS)" \ ./tools/mkimage/Makefile: $(MAKE) -C $(HOST_BUILD_DIR) defconfig HOSTCFLAGS="$(HOST_CPPFLAGS) $(HOST_CFLAGS)" HOSTLDFLAGS="$(HOST_LDFLAGS)" HOST_LOADLIBES="$$$$(pkg-config --static --libs libcrypto)" ./tools/mkimage/Makefile: $(MAKE) -C $(HOST_BUILD_DIR) tools-only HOSTCFLAGS="$(HOST_CPPFLAGS) $(HOST_CFLAGS)" HOSTLDFLAGS="$(HOST_LDFLAGS)" HOST_LOADLIBES="$$$$(pkg-config --static --libs libcrypto)" ./include/host-build.mk: CPPFLAGS="$(HOST_CPPFLAGS)" \ ./include/host-build.mk: CPPFLAGS="$(HOST_CPPFLAGS)" \ ./rules.mk:HOST_CPPFLAGS:=-I$(STAGING_DIR_HOST)/include -I$(STAGING_DIR_HOST)/usr/include $(if $(IS_PACKAGE_BUILD),-I$(STAGING_DIR_HOSTPKG)/include -I$(STAGING_DIR)/host/include) ./rules.mk:HOST_CFLAGS:=-O2 $(HOST_CPPFLAGS) txt@txt:/media/ssd/lede$ ``` and ``` txt@fr:~/workspace/lede-master$ make -j1 V=s package/uboot-omap/compile […] # # configuration written to .config # make[3]: Leaving directory `/home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/u-boot-am335x_boneblack/u-boot-2017.01' rm -f /home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/u-boot-am335x_boneblack/u-boot-2017.01/.configured_* touch /home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/u-boot-am335x_boneblack/u-boot-2017.01/.configured_68b329da9893e34099c7d8ad5cb9c940 rm -f /home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/u-boot-am335x_boneblack/u-boot-2017.01/.built touch /home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/u-boot-am335x_boneblack/u-boot-2017.01/.built_check make -C /home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/u-boot-am335x_boneblack/u-boot-2017.01 CROSS_COMPILE=arm-openwrt-linux-muslgnueabi- DTC="/home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/linux-omap/linux-4.4.71/scripts/dtc/dtc" HOSTCC="gcc" HOSTCFLAGS='-O2 -I/home/txt/workspace/lede-master/staging_dir/host/include -I/home/txt/workspace/lede-master/staging_dir/host/usr/include -I/home/txt/workspace/lede-master/staging_dir/hostpkg/include -I/home/txt/workspace/lede-master/staging_dir/target-arm_cortex-a8+vfpv3_musl_eabi/host/include $$(HOSTCPPFLAGS)' HOSTLDFLAGS="" make[3]: Entering directory `/home/txt/workspace/lede-master/build_dir/target-arm_cortex-a8+vfpv3_musl_eabi/u-boot-am335x_boneblack/u-boot-2017.01' HOSTCC scripts/basic/fixdep /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found HOSTCC scripts/kconfig/conf.o /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found /bin/sh: HOSTCPPFLAGS: command not found HOSTCC scripts/kconfig/zconf.tab.o /bin/sh: HOSTCPPFLAGS: command not found HOSTLD scripts/kconfig/conf scripts/kconfig/conf --silentoldconfig Kconfig CHK include/config.h UPD include/config.h CFG u-boot.cfg GEN include/autoconf.mk ^Cmake[4]: *** Deleting file `include/autoconf.mk' make[3]: *** Deleting file `include/config/auto.conf' ```
With one $ sign the "/bin/sh: HOSTCPPFLAGS: command not found" line is gone. uboot-omap and uboot-sunxi still compile. I did not test all uboot-… packages. kind regards txt.file -- This message is signed.
