issuing “$ make clean", and run “$ make" again, I see the flag, but the “make” output is still stopping with the error: > make -C > /Volumes/Case-sensitive/Entware-ng/build_dir/toolchain-mipsel_mips32r2_gcc-5.3.0_uClibc-1.0.16/uClibc-ng-1.0.16 > > PREFIX="/Volumes/Case-sensitive/Entware-ng/build_dir/toolchain-mipsel_mips32r2_gcc-5.3.0_uClibc-1.0.16/uClibc-dev/" > DEVEL_PREFIX=/ > RUNTIME_PREFIX="/Volumes/Case-sensitive/Entware-ng/build_dir/toolchain-mipsel_mips32r2_gcc-5.3.0_uClibc-1.0.16/uClibc-dev/" > HOSTCC="gcc" CC="mipsel-openwrt-linux-uclibc-gcc" CPU_CFLAGS="-O2 -pipe > -mno-branch-likely -mips32r2 -mtune=mips32r2 -fno-caller-saves -fhonour-copts > -Wno-error=unused-but-set-variable -Wno-error=unused-result -msoft-float" > UCLIBC_EXTRA_CFLAGS=" -I../../include" ARCH=""mipsel"" pregen install_headers However the Makefile result at /Volumes/Case-sensitive/Entware-ng/build_dir/toolchain-mipsel_mips32r2_gcc-5.3.0_uClibc-1.0.16/uClibc-ng-1.0.16/extra/locale, is missing this -I../../include flag: > /Applications/Xcode.app/Contents/Developer/usr/bin/make -C extra/locale > locale_headers > gcc ../../extra/locale/gen_locale.c -o ../..//extra/locale/gen_locale -Os > -D_GNU_SOURCE -I../..//extra/locale Possibly I haven’t yet understood how to insert extra CFLAGS for uClibc headers, or the UCLIBC_EXTRA_CFLAGS flag doesn’t flow down into the toolchain as it should. -- Best regards, ~Ceriel Op 22 nov. 2016, om 13:23 heeft Waldemar Brodkorb <w...@uclibc-ng.org> het volgende geschreven: > Hi Ceriel, > C.
