From: H.J. Lu Date: Tue, 31 Mar 2015 15:24:02 +0000 (-0700) Subject: Add --with-system-zlib in gdb X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=711a72d3d6f8cd3c3f408e718ff19aa4bfd2144e;p=binutils-gdb.git Add --with-system-zlib in gdb This patch adds --with-system-zlib and removes --with-zlib in gdb. * Makefile.in (ZLIB): New. (ZLIBINC): Likewise. (INTERNAL_CFLAGS_BASE): Add $(ZLIBINC). (CLIBS): Add $(ZLIB). * acinclude.m4: (GDB_AC_CHECK_BFD): Add $zlibdir to LDFLAGS. Add -lz to LIBS. * gdb_bfd.c: Don't check HAVE_ZLIB_H to include . * top.c (print_gdb_configuration): Remove --with-zlib and --without-zlib. * config.in: Regenerated. * configure: Likewise. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 757ffd24d46..160de2dc493 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,17 @@ +2015-03-31 H.J.
