It's vital that this compiler runs in the bootstrap machine, and # targets the same machine (TARGET_STAGE1) so that the stage 1 GCC # is used instead of the compiler of the build machine. # 2. See gcc.morph. # 3. Disable searching /usr/local/include for headers # 4. This flag causes the correct --sysroot flag to be passed when # calling stage 1 GCC. - | case "%{bst-arch}" in armv7lhf) ARCH_FLAGS="--with-arch=armv7-a \ --with-cpu=cortex-a9 \ --with-tune=cortex-a9 \ --with-fpu=vfpv3-d16 \ --with-float=hard" ;; armv7*) ARCH_FLAGS="--with-arch=armv7-a" ;; esac export STAGE2_SYSROOT="$(dirname $(dirname $(pwd)))" export CC="%{target-stage1}-gcc --sysroot=$STAGE2_SYSROOT" export CXX="%{target-stage1}-g++ --sysroot=$STAGE2_SYSROOT" export AR="%{target-stage1}-ar" export RANLIB="%{target-stage1}-ranlib" cd o && ../configure \ $ARCH_FLAGS \ --build=$(sh ../config.guess) \ `# [1]` --host=%{target-stage1} \ `# [1]` --target=%{target-stage1} \ --prefix="%{prefix}" \ `# [2]` --libdir=%{prefix}/lib \ `# [3]` --with-local-prefix=%{prefix} \ `# [4]` --with-build-sysroot="$STAGE2_SYSROOT" \ --disable-bootstrap \ --disable-nls \ --disable-multilib \ --disable-libgomp \ --disable-libstdcxx-pch \ --enable-languages=c,c++ build-commands: - | case "%{bst-arch}" in armv5*) sed -i "s/--host=none/--host=armv5/" o/Makefile sed -i "s/--target=none/--target=armv5/" o/Makefile ;; armv7*) sed -i "s/--host=none/--host=armv7a/" o/Makefile sed -i "s/--target=none/--target=armv7a/" o/Makefile ;; esac export STAGE2_SYSROOT="$(dirname $(dirname $(pwd)))" cd o && make install-commands: - cd o && make DESTDIR="%{install-root}" install # Stage 3 builds need to link against this file in the location that # it will be in the final system, so we make a temporary link now. # # On x86_64 GCC resolutely installs its libraries into lib64.
