I get an error during the second pass of eglibc crt1.o is little- endian and we are building for a big-endian system. So, I change CC=${cross_cc} \ to CC="${cross_cc} -EB" \ in the file: <http://ymorin.is-a-geek.org/hg/crosstool-ng/file/f4e5daf96796/scripts/build/libc/glibc-eglibc.sh-common#l42> and then I get a gcc build error (not even going to try to wrap this puppy): [ALL ] /root/src/buildroot-retool/crosstool-ng/new/crosstool-ng/.build/mips-nfs_devel-linux-gnu/build/build-cc-core-shared/./gcc/xgcc -B/root/src/buildroot-retool/crosstool-ng/new/crosstool-ng/.build/mips-nfs_devel-linux-gnu/build/build-cc-core-shared/./gcc/ -B/root/src/buildroot-retool/crosstool-ng/new/crosstool-ng/.build/mips-nfs_devel-linux-gnu/build/gcc-core-shared/mips-nfs_devel-linux-gnu/bin/ -B/root/src/buildroot-retool/crosstool-ng/new/crosstool-ng/.build/mips-nfs_devel-linux-gnu/build/gcc-core-shared/mips-nfs_devel-linux-gnu/lib/ -isystem /root/src/buildroot-retool/crosstool-ng/new/crosstool-ng/.build/mips-nfs_devel-linux-gnu/build/gcc-core-shared/mips-nfs_devel-linux-gnu/include -isystem /root/src/buildroot-retool/crosstool-ng/new/crosstool-ng/.build/mips-nfs_devel-linux-gnu/build/gcc-core-shared/mips-nfs_devel-linux-gnu/sys-include -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 -Wl,--version-script=libgcc.map -o ./libgcc_s.so.1.tmp -g -Os -B./ _m16addsf3_s.o _m16subsf3_s.o _m16mulsf3_s.o _m16divsf3_s.o _m16eqsf2_s.o _m16nesf2_s.o _m16gtsf2_s.o _m16gesf2_s.o _m16lesf2_s.o _m16ltsf2_s.o _m16unordsf2_s.o _m16fltsisf_s.o _m16fix_truncsfsi_s.o _m16fltuns <snip all the .o files> bc_s.o unwind-sjlj_s.o gthr-gnat_s.o unwind-c_s.o emutls_s.o && rm -f ./libgcc_s.so && if [ -f ./libgcc_s.so.1 ];

[ERROR] (elapsed: 10:53.39) make: *** [build] Error 2 So, how do we get xgcc to start passing the "-mips32r2 -EB" so that libgcc_s.so.1 gets built correctly? If you see the issue, please help. I've been at this for over a week and I cannot find how to get the GCC build to behave itself. Thanks, Andy
