Hello I'm using GCC 4.7.0 on an Android device to bootstrap version 4.8.0...specifically the c++ compiler. After some trial and error I've successfully built and installed binutils 2.23.2,and have configured gcc 4.8, but make fails with the following cc1-checksum.o libbackend.a main.o libcommon-target.a libcommon.a ../libcpp/libcpp.a ../libdecnumber/libdecnumber.a libcommon.a ../libcpp/libcpp.a ./../intl/libintl.a ../libbacktrace/.libs/libbacktrace.a ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -L/bld/gcc/4.8-buildgcc/./gmp/.libs -L/bld/gcc/4.8-buildgcc/./mpfr/.libs -L/bld/gcc/4.8-buildgcc/./mpc/src/.libs -lmpc -lmpfr -lgmp -rdynamic -L../zlib -lz libcommon.a(diagnostic.o): In function `diagnostic_action_after_output': /bld/gcc/4.8-buildgcc/gcc/../../gcc-4.8.0/gcc/diagnostic.c:437: undefined reference to `backtrace_full' ../libbacktrace/.libs/libbacktrace.a(state.o): In function `backtrace_create_state': state.c:(.text+0x3c): undefined reference to `backtrace_alloc' collect2: error: ld returned 1 exit status make[2]: *** [cc1] Error 1 make[2]: Leaving directory `/bld/gcc/4.8-buildgcc/gcc' make[1]: *** [all-gcc] Error 2 make[1]: Leaving directory `/bld/gcc/4.8-buildgcc' make: *** [all] Error 2 I've grepped and found backtrace_full in backtrace.o...which I assume was included in libbacktrace. Not sure what's failing here, so any advice/help is appreciated My configure options were as follows: /bld/gcc/4.8-buildgcc $ ../gcc-4.8.0/configure --prefix=/usr/gcc-4.8 --build=arm-linux-androideabi --host=arm-linux-androideabi --target=arm-linux-androideabi --disable-ld --with-as=/usr/gcc-4.8/bin/as --with-ld=/usr/gcc-4.8/bin/ld --enable-version-specific-runtime-libs --enable-shared --enable-languages=c,c++ --disable-bootstrap -disable-gold --disable-fortran --disable-libssp --disable-libquadmath --disable-libquadmath-support --disable-libada --disable-werror --disable-multilib --disable-libgomp --disable-cloog --with-build-time-tools=/usr/gcc-4.8/bin --with-build-sysroot=/usr/lib/gcc/arm-linux-androideabi/4.7/arm-linux-androideabi CC='gcc --sysroot=/usr/lib/gcc/arm-linux-androideabi/4.7/arm-linux-androideabi' CFLAGS='-Wall -O -mandroid -mbionic' LDFLAGS='-Wl,--dynamic-linker=/system/bin/linker -lc -ldl -lgcc -lm' LIBCFLAGS='-O2 -mandroid -mbionic' LIBCPPFLAGS='-O2 -mandroid -mbionic' LIBCXXFLAGS='-O2 -mandroid -mbionic -fno-implicit-templates' LIBS='-lc -ldl -lgcc -lm -lsupc++ -lgnustl_shared'
