Hi all, I'm trying to build a x86_64-to-x86_64 cross-compiler with a sysroot

With a few minor corrections and amendments, I get to the very last step
where the full compiler is built and hit the following issue:

I am using glibc 2.16.0 and have no idea where this thing came from. The
binary does not run as the system's glibc (well, that very .so) is version
2.12.
I built glibc this way:
../glibc-2.16.0/configure --prefix=/work/osmolsky/_gcc-sr-build/gcc48
--target=x86_64-unknown-linux-gnu
--with-headers=/work/osmolsky/_gcc-sr-build/sysroot/usr/include
--enable-kernel=2.6.32 --without-selinux
make install_root=/work/osmolsky/_gcc-sr-build/sysroot prefix="" install
Could somebody shed some light on this please? Is this configuration
supported? Am I missing something vital?
Thanks in advance!
Oleg.
Try adding glibc-2.16.0 installed lib in to your LD_LIBRARY_PATH.
Right, that was the first thing I tried, but I cannot get this binary to
load on the host system (even though host and target are the same):
