hi,

so the error when building the o32 library is on the following line:

to reproduce this, build the cross binutils as follows
(CLFS_HOST=x86_64-apple-darwin, CLFS_TARGET=mips64el-none-linux-gnu):

http://clfs.org/view/sysvinit/mips64/cross-tools/binutils.html
<http://clfs.org/view/sysvinit/mips64/cross-tools/binutils.html>
AR=ar AS=as \
../binutils-2.28/configure \
    --prefix=/cross-tools \
    --host=${CLFS_HOST} \
    --target=${CLFS_TARGET} \
    --with-sysroot=${CLFS} \
    --with-lib-path=/tools/lib:/tools/lib64 \
    --disable-nls \
    --disable-static \
    --enable-64-bit-bfd \
    --enable-gold=yes \
    --enable-plugins \
    --enable-threads \
    --disable-werror

and the static gcc (doesn’t matter whether it’s the static or shared library
variant, as you all should be aware, since we’re building glibc):

http://clfs.org/view/sysvinit/mips64/cross-tools/gcc-static.html
<http://clfs.org/view/sysvinit/mips64/cross-tools/gcc-static.html>

AR=ar \
LDFLAGS="-Wl,-rpath,/cross-tools/lib" \
../gcc-7.1.0/configure \
    --prefix=/cross-tools \
    --build=${CLFS_HOST} \
    --host=${CLFS_HOST} \
    --target=${CLFS_TARGET} \
    --with-sysroot=${CLFS} \
    --with-local-prefix=/tools \
    --with-native-system-header-dir=/tools/include \
    --disable-shared \
    --with-mpfr=/cross-tools \
    --with-gmp=/cross-tools \
    --with-mpc=/cross-tools \
    --without-headers \
    --with-newlib \
    --disable-decimal-float \
    --disable-libgomp \
    --disable-libssp \
    --disable-libatomic \
    --disable-libitm \
    --disable-libsanitizer \
    --disable-libquadmath \
    --disable-libvtv \
    --disable-libcilkrts \
    --disable-libstdc++-v3 \
    --disable-threads \
    --with-isl=/cross-tools \
    --enable-languages=c \
    --with-glibc-version=2.25

then when building the o32 GLIBC will fail using the following:

http://clfs.org/view/sysvinit/mips64/cross-tools/glibc.html
BUILD_CC="gcc" CC="${CLFS_TARGET}-gcc ${BUILD32}" \
AR="${CLFS_TARGET}-ar" RANLIB="${CLFS_TARGET}-ranlib" \
../glibc-2.25/configure \
    --prefix=/tools \
    --host=${CLFS_TARGET32} \
    --build=${CLFS_HOST} \
    --enable-kernel=3.12.0 \
    --with-binutils=/cross-tools/bin \
    --with-headers=/tools/include \
    --enable-obsolete-rpc
when CLFS_TARGET32 is set to mipsel-none-linux-gnu

neither the 64 or n32 have this problem, which leads me to believe this is
solely due to the host being 32bit. it has to be something small that causes a
downstream issue with elfxx-mips

Thanks,
Gagan
