I imported zlib from GCC.  This patch adds --with-system-zlib and

I think the global binutils-gdb Makefile needs to have a dependency of
bfd on zlib.  If I build 'all-binutils' (using just the binutils-gdb
repository, not a combined tree with GCC) I get a build failure.  If I
explicitly build all-zlib before building all-binutils it works, but I
should not have to do that.

I will take a look.

It seems GDB's is also missing a few bits to make sure it
includes ../zlib/libz.a in the final link step, otherwise it tries to pick
the system's zlib instead of the included zlib, which may fail if you have
an older libz installed.


/usr/bin/ld: ../bfd/libbfd.a(compress.o): undefined reference to symbol
//lib/x86_64-linux-gnu/ error adding symbols: DSO missing from

We need something like libiberty in gdb/, but conditionalized
based on the configure switches to use the system's or the include zlib.

Please check out users/hjl/zlib branch.

That fixed it.
