From c5adaa1921c34d2b9711ec7cecd3cb4a253620db Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 29 Aug 2019 10:39:57 -0400 Subject: Fix creation of stamp-h by gdb's configure script I happened to notice that "make" would always print: CONFIG_HEADERS=config.h:config.in \ CONFIG_COMMANDS="default depdir" \ CONFIG_FILES= \ CONFIG_LINKS= \ /bin/sh config.status config.status: creating config.h config.status: config.h is unchanged on every rebuild. This seems to have changed due to an autoconf upgrade at some point in the past. In the autoconf gdb uses now, it works to use AC_CONFIG_HEADERS and then create the stamp file via the "commands" argument. This patch also fixes up Makefile.in to use the new-style config.status invocation. It's no longer necessary to pass the output file names via environment variables. gdb/ChangeLog 2019-10-17 Tom Tromey * configure: Rebuild. * configure.ac: Use AC_CONFIG_HEADERS. Create stamp-h there, not in AC_CONFIG_FILES invocation. * Makefile.in (Makefile, data-directory/Makefile, stamp-h): Use new-style config.status invocation. gdb/gdbserver/ChangeLog 2019-10-17 Tom Tromey * configure: Rebuild. * configure.ac: Use AC_CONFIG_HEADERS.
