Message-ID: <AM0PR0602MB3410D4C201AEA1DC07E19AF5E4DC0@AM0PR0602MB3410.eurprd06.prod.outlook.com> (raw)

Hi everybody,
I have now two possible ways to go forward with the configure options
for gmp and mpfr.
See the attached patches:
Variant 1: implements traditional configure options
--with-gmp-include=DIR, --with-gmp-lib=DIR, --with-gmp=DIR,
--with-mpfr-include=DIR, --with-mpfr-lib=DIR, --with-mpfr=DIR
but does additionally understand --with-libmpfr-prefix=DIR
and --with-mpfr=auto/yes/no.
Variant 2: (I already posted that one) keeps all configure options
as they are now, and just uses the presence of a ../gmp and ../mpfr
directory to override the gmp and mpfr configure flags.
I would be interested in what you think, and which variant you would
prefer.
Thanks
Bernd.

Subject: [PATCH] Enable GDB build with in-tree GMP and MPFR
With this patch GDB can be built with in-tree GMP and/or
MPFR. This works also for cross-builds.
All that is needed, is a sym-link in the source tree,
like this:
gmp -> ../gmp-6.1.0
mpfr -> ../mpfr-3.1.4
2020-12-10 Bernd Edlinger <bernd.edlinger@hotmail.de>
* Makefile.def: Prepare for GDB build with intree GMP.
* Makefile.in: Regenerate.
gdb:
2020-12-10 Bernd Edlinger <bernd.edlinger@hotmail.de>
* configure.ac: Add --with-gmp=DIR, --with-gmp-include=DIR
and --with-gmp-lib=DIR
as well as --with-mpfr-include=DIR and --with-mpfr-lib=DIR
for compatibility with top level configure script.
* configure: Regenerate.
* README: Mention ./contrib/download_prerequisites.
contrib:
2020-12-10 Bernd Edlinger <bernd.edlinger@hotmail.de>
* download_prerequisites: New helper script.
* prerequisites.md5: checksums.
* prerequisites.sha512: checksums.

From b7cd2ebb1f555397885279a2ace6bd46ca4f5643 Mon Sep 17 00:00:00 2001
From: Bernd Edlinger <bernd.edlinger@hotmail.de>
Date: Sun, 15 Nov 2020 15:37:22 +0100
Subject: [PATCH] Enable GDB build with in-tree GMP and MPFR
With this patch GDB can be built with in-tree GMP and/or
MPFR. This works also for cross-builds.
All that is needed, is a sym-link in the source tree,
like this:
gmp -> ../gmp-6.1.0
mpfr -> ../mpfr-3.1.4
2020-12-10 Bernd Edlinger <bernd.edlinger@hotmail.de>
* Makefile.def: Prepare for GDB build with intree GMP.
* Makefile.in: Regenerate.
gdb:
2020-12-10 Bernd Edlinger <bernd.edlinger@hotmail.de>
* configure.ac: Detect in-tree GMP and MPFR.
* configure: Regenerate.
* README: Mention ./contrib/download_prerequisites.
contrib:
2020-12-10 Bernd Edlinger <bernd.edlinger@hotmail.de>
* download_prerequisites: New helper script.
* prerequisites.md5: checksums.
* prerequisites.sha512: checksums.
