I configure gcc-5.2.0 with the option --disable-libatomic, but I don't known
the meaning of it. There are no explanation descripthon in <Installing GCC
:Configuration>. could anyone can tell me ?

I have configure binutils with follow configruation:
../binutils-2.25/configure --prefix=$CROSS_TOOL --target=$TARGET
--with-sysroot=$SYSROOT
#$CROSS_TOOL=/sig/cross-tool $TARGET=x86_64-none-linux-gnu
$HOST=x86_64-unknown-linux-gnu $SYSROOT=/sig/sysroot -----the directory
/sig/sysroot is emtpy
after i install glibc with
$../glibc-2.22.0/configure --prefix=/usr --host=$TARGET --enable-kernel=4.4
--disable-profile --enable-add-ons --with-headers=$SYSROOT/usr/include
libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes libc_cv_ctors_header=yes
--enable-obsolete-rpc
$make
$make install_root=$SYSROOT install
gcc-5.2.0 configure with:
../glibc-2.22.0/configure --prefix=/usr --host=$TARGET --enable-kernel=4.4
--disable-profile --enable-add-ons --with-headers=$SYSROOT/usr/include
libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes libc_cv_ctors_header=yes
--enable-obsolete-rpc
how to add /sig/sysroot/lib64 to ld(the one i just complie) lib search path? i
have try the environment Variables LIBRARY_PATH,but it don't work
$ echo $LIBRARY_PATH
/sig/sysroot/lib64/:/sig/sysroot/usr/lib64
$ $CC test.c
/sig/cross-tool/lib/gcc/x86_64-none-linux-gnu/5.2.0/../../../../x86_64-none-linux-gnu/bin/ld:
cannot find crt1.o: No such file or directory
/sig/cross-tool/lib/gcc/x86_64-none-linux-gnu/5.2.0/../../../../x86_64-none-linux-gnu/bin/ld:
cannot find crti.o: No such file or directory
collect2: error: ld returned 1 exit status
but i can compile whit
$ $CC -B /sig/sysroot/usr/lib64 test.c
