I am trying to build gcc-4.2.1. I see in the prerequisites the following.
GNU Multiple Precision Library (GMP) version 4.1 (or later)
Necessary to build GCC. If you do not have it installed in your library
search path, you will have to configure with the --with-gmp configure
option. See also --with-gmp-lib and --with-gmp-include.
MPFR Library version 2.2.1 (or later)
Necessary to build GCC. It can be downloaded from http://www.mpfr.org/. The
version of MPFR that is bundled with GMP 4.1.x contains numerous bugs.
Although GCC may appear to function with the buggy versions of MPFR, there
are a few bugs that will not be fixed when using this version. It is
strongly recommended to upgrade to the recommended version of MPFR.
The --with-mpfr configure option should be used if your MPFR Library is not
installed in your default library search path. See also --with-mpfr-lib and
--with-mpfr-include.
I am using GNU/Linux redhat release 4 to do the building. I am also trying
to build a gcc and all the other gnu utilities that are standalone from
those provided with the operating system. The reason for this is that I also
am building the same set of tools on solaris 8. The paths on each OS has to
be the same for the ease of use by the users and tools.
I see that the gmp and/or mpfr versions of the GNU/Linux system are older
then those available on the net. I want to build the gcc using these newer
versions. I have tried a number of ways to accomplish this but the bootstrap
build seems to not find my newer version in the later build pass.
Has someone else done this? Does anyone know how I might accomplish this?
It seems like the two libraries should each be built as part of the gcc
build itself. This way they are installed in the gcc include/lib directories
during the process.
You could look up previous discussions on these points. You're entitled
to include gmp and mpfr in your build setup. Experts considered
seriously whether to include them in the gcc source distribution, and
didn't conclude that it would be a good solution.
You can never expect even the newest Red Hat distros to come with
satisfactory gnu utilities (binutils, dejagnu, gmp, mpfr,....) . For
example, Red Hat 4.x fixed the versions of such utilities long before
beginning development of 4.0, even though many months of additional
development went into the 4.4,4.5 versions which are currently usable.
They're up to 5.1 now, but even that is nowhere near as up to date as
Fedora 7 or SuSE 10.2. If you want minimum required updates included in
your linux installation, there's Oracle linux, or there's SuSE with
online update.
One of the mpfr pitfalls should be remedied by the inclusion of
--enable-shared as a default in the newest versions. My personal way of
dealing with it is to configure the gmp and mpfr with --prefix=/usr
--enable-shared, so that when I install, all the old libraries are
replaced. I probably don't count as a someone according to your query.
