I'm attempting to compile gcc --with-sysroot. I've installed the linux headers and compiled and installed binutils and glibc for this sysroot. binutils is installed in $sysroot/opt/xbinutils and glibc is installed in $sysroot/opt/xglibc. I've specified the location of binutils using --with-build-time-tools. I've specified the location of the glibc headers using --with-native-system-header-dir. How do I specify the location of the glibc libraries? I'm looking for something like --with-native-system-lib-dir. When building libgcc_s.so, I'm getting the error cannot find crti.o: No such file or directory (see below). gcc 4.9.1 binutils 2.24 glibc 2.19 linux headers 3.15.9 The configure line is ../configure --with-sysroot=/home/sjackman/.linuxbrew --prefix=/Cellar/xgcc/4.9.1 --with-native-system-header-dir=/opt/xglibc/include --with-build-time-tools=/opt/xbinutils/bin --enable-languages=c,c++,objc,obj-c++,fortran --program-suffix=-4.9 --with-gmp=/home/sjackman/.linuxbrew/opt/gmp --with-mpfr=/home/sjackman/.linuxbrew/opt/mpfr --with-mpc=/home/sjackman/.linuxbrew/opt/libmpc --with-cloog=/home/sjackman/.linuxbrew/opt/cloog --with-isl=/home/sjackman/.linuxbrew/opt/isl --with-system-zlib --enable-libstdcxx-time=yes --enable-stage1-checking --enable-checking=release --enable-lto --disable-werror --with-pkgversion='Homebrew xgcc 4.9.1' --without-multilib --with-bugurl='https://github.com/Homebrew/homebrew/issues' --enable-plugin --disable-nls --disable-multilib Thanks, Shaun http://sjackman.ca /var/tmp/sjackman/xgcc-vn5822/gcc-4.9.1/build/./gcc/xgcc -B/var/tmp/sjackman/xgcc-vn5822/gcc-4.9.1/build/./gcc/ -B/Cellar/xgcc/4.9.1/x86_64-unknown-linux-gnu/bin/ -B/Cellar/xgcc/4.9.1/x86_64-unknown-linux-gnu/lib/ -isystem /Cellar/xgcc/4.9.1/x86_64-unknown-linux-gnu/include -isystem /Cellar/xgcc/4.9.1/x86_64-unknown-linux-gnu/sys-include -O2 -g -O2 -Os -w -pipe -march=core2 -DIN_GCC -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fpic -mlong-double-80 -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 -Wl,--version-script=libgcc.map -o ./libgcc_s.so.1.tmp -g -O2 -Os -w -pipe -march=core2 -B./ _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 _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 _clzsi2_s.o _clzdi2_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 _mulsc3_s.o _muldc3_s.o _mulxc3_s.o _divsc3_s.o _divdc3_s.o _divxc3_s.o _bswapsi2_s.o _bswapdi2_s.o _clrsbsi2_s.o _clrsbdi2_s.o _fixunssfsi_s.o _fixunsdfsi_s.o _fixunsxfsi_s.o _fixsfdi_s.o _fixdfdi_s.o _fixxfdi_s.o _fixunssfdi_s.o _fixunsdfdi_s.o _fixunsxfdi_s.o _floatdisf_s.o _floatdidf_s.o _floatdixf_s.o _floatundisf_s.o _floatundidf_s.o _floatundixf_s.o _divdi3_s.o _moddi3_s.o _udivdi3_s.o _umoddi3_s.o _udiv_w_sdiv_s.o _udivmoddi4_s.o cpuinfo_s.o sfp-exceptions_s.o addtf3_s.o divtf3_s.o multf3_s.o negtf2_s.o subtf3_s.o unordtf2_s.o fixtfsi_s.o fixunstfsi_s.o floatsitf_s.o floatunsitf_s.o fixtfdi_s.o fixunstfdi_s.o floatditf_s.o floatunditf_s.o fixtfti_s.o fixunstfti_s.o floattitf_s.o floatuntitf_s.o extendsftf2_s.o extenddftf2_s.o extendxftf2_s.o trunctfsf2_s.o trunctfdf2_s.o trunctfxf2_s.o getf2_s.o letf2_s.o eqtf2_s.o _divtc3_s.o _multc3_s.o _powitf2_s.o enable-execute-stack_s.o unwind-dw2_s.o unwind-dw2-fde-dip_s.o unwind-sjlj_s.o unwind-c_s.o emutls_s.o libgcc.a -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/sjackman/.linuxbrew/opt/xbinutils/bin/ld: cannot find crti.o: No such file or directory /home/sjackman/.linuxbrew/opt/xbinutils/bin/ld: cannot find -lc /home/sjackman/.linuxbrew/opt/xbinutils/bin/ld: cannot find crtn.o: No such file or directory collect2: error: ld returned 1 exit status make: *** [libgcc_s.so] Error 1
