Hi, I am builing gcc cross compiler tool chain for arm-unknown-linux-gnueabi. I have build and installed binutils-2.21.1 with following configure line $ ../../src/binutils-2.21.1/configure --prefix=/home/jack/linux/tools --target=arm-unknown-linux-gnu --with-sysroot=/home/jack/linux/tools/sysroot also I have installed the linux-3.1 and glibc-2.14.1 in /home/jack/linux/tools/sysroot/ in /usr/include ... using following $ make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi INSTALL_HDR_PATH=/home/jack/linux/tools/sysroot/usr $ ../../src/glibc-2.14.1/configure --prefix=/usr --host=arm-unknown-linux-gnu --with-headers=/home/jack/linux/tools/sysroot/usr/include host_alias=arm-unknown-linux-gnu --no-create --no-recursion >>>> Above lines are directly copied from config.log Now, I have configured gcc with $ ../../src/gcc-4.6.1/configure --prefix=/home/jack/linux/tools --target=arm-unknown-linux-gnu --enable-languages=c --with-sysroot=/home/jack/linux/tools/sysroot --disable-multilib --disable-bootstrap and it is showing error: /home/jack/linux/build/gcc-build/./gcc/xgcc -B/home/jack/linux/build/gcc-build/./gcc/ -B/home/jack/linux/tools/arm-unknown-linux-gnu/bin/ -B/home/jack/linux/tools/arm-unknown-linux-gnu/lib/ -isystem /home/jack/linux/tools/arm-unknown-linux-gnu/include -isystem /home/jack/linux/tools/arm-unknown-linux-gnu/sys-include -O2 -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fomit-frame-pointer -fPIC -Wno-missing-prototypes -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -fno-stack-protector -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 -Wl,--version-script=libgcc.map -o ./libgcc_s.so.1.tmp -g -O2 -B./ _udivsi3_s.o _divsi3_s.o _umodsi3_s.o _modsi3_s.o _dvmd_lnx_s.o _clzsi2_s.o _clzdi2_s.o _arm_addsubdf3_s.o _arm_addsubsf3_s.o _muldi3_s.o _negdi2_s.o _lshrdi3_s.o _ashldi3_s.o _ashrdi3_s.o _cmpdi2_s.o _ucmpdi2_s.o _clear_cache_s.o _enable_execute_stack_s.o _trampoline_s.o __main_s.o _absvsi2_s.o _absvdi2_s.o _addvsi3_s.o _addvdi3_s.o _subvsi3_s.o _subvdi3_s.o _mulvsi3_s.o _mulvdi3_s.o _negvsi2_s.o _negvdi2_s.o _ctors_s.o _ffssi2_s.o _ffsdi2_s.o _clz_s.o _ctzsi2_s.o _ctzdi2_s.o _popcount_tab_s.o _popcountsi2_s.o _popcountdi2_s.o _paritysi2_s.o _paritydi2_s.o _powisf2_s.o _powidf2_s.o _powixf2_s.o _powitf2_s.o _mulsc3_s.o _muldc3_s.o _mulxc3_s.o _multc3_s.o _divsc3_s.o _divdc3_s.o _divxc3_s.o _divtc3_s.o _bswapsi2_s.o _bswapdi2_s.o _fixunssfsi_s.o _fixunsdfsi_s.o _fixunsxfsi_s.o _fixsfdi_s.o _fixdfdi_s.o _fixxfdi_s.o _fixtfdi_s.o _fixunssfdi_s.o _fixunsdfdi_s.o _fixunsxfdi_s.o _fixunstfdi_s.o _floatdisf_s.o _floatdidf_s.o _floatdixf_s.o _floatditf_s.o _floatundisf_s.o _floatundidf_s.o _floatundixf_s.o _floatunditf_s.o _divdi3_s.o _moddi3_s.o _udivdi3_s.o _umoddi3_s.o _udiv_w_sdiv_s.o _udivmoddi4_s.o addsf3_s.o divsf3_s.o eqsf2_s.o gesf2_s.o lesf2_s.o mulsf3_s.o negsf2_s.o subsf3_s.o unordsf2_s.o fixsfsi_s.o floatsisf_s.o floatunsisf_s.o adddf3_s.o divdf3_s.o eqdf2_s.o gedf2_s.o ledf2_s.o muldf3_s.o negdf2_s.o subdf3_s.o unorddf2_s.o fixdfsi_s.o floatsidf_s.o floatunsidf_s.o extendsfdf2_s.o truncdfsf2_s.o unwind-dw2_s.o unwind-dw2-fde-glibc_s.o unwind-sjlj_s.o gthr-gnat_s.o unwind-c_s.o emutls_s.o -lc && rm -f ./libgcc_s.so && if [ -f ./libgcc_s.so.1 ]; then mv -f ./libgcc_s.so.1 ./libgcc_s.so.1.backup; else true; fi && mv ./libgcc_s.so.1.tmp ./libgcc_s.so.1 && ln -s libgcc_s.so.1 ./libgcc_s.so /home/jack/linux/tools/arm-unknown-linux-gnu/bin/ld: cannot find crti.o: No such file or directory /home/jack/linux/tools/arm-unknown-linux-gnu/bin/ld: cannot find -lc /home/jack/linux/tools/arm-unknown-linux-gnu/bin/ld: cannot find crtn.o: No such file or directory collect2: ld returned 1 exit status make[2]: *** [libgcc_s.so] Error 1 make[2]: Leaving directory `/home/jack/linux/build/gcc-build/arm-unknown-linux-gnu/libgcc' make[1]: *** [all-target-libgcc] Error 2 make[1]: Leaving directory `/home/jack/linux/build/gcc-build' make: *** [all] Error 2 Thankyou for Help in Advance.
