completely unable to get Gcc 4.4.5 to build with local Gmp/Mpfr

[Oliver Kullmann <O dot Kullmann at swansea dot ac dot uk>]

Hello,

we want to build Gcc 4.4.5, C, C++, Fortran,
without any system-wide installation of Gmp or Mpfr.

First we tried for a long time in vain to get Gcc to acknowledge
local installations of Gmp and Mpfr: the Gcc-build is defect,
and doesn't propagate linking-information to the build of libraries
(like libgcc or libgfortran).

Okay, we gave up on that, and just want to use what the manual says:

-----------------
Alternatively, if a GMP source distribution is found in a subdirectory of your GCC sources named gmp, it will be built together with GCC. 
Alternatively, if a MPFR source distribution is found in a subdirectory of your GCC sources named mpfr, it will be built together with GCC. 
----------------

Not clear what a "source distribution" precisely is, but the build starts promissing when
providing the sources like so:

> ls gcc-4.4.5/gmp/
gmp-5.0.1.tar.bz2
> ls gcc-4.4.5/mpfr/
mpfr-3.0.0.tar.bz2

Now installing Gcc with

gcc-4.4.5_build> ../gcc-4.4.5/configure 
  --prefix=/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.4.5 
  --enable-languages=c,c++,fortran 
  --enable-threads=posix 
  --enable-shared

after some time we get the error

which is not too surprising since neither Gmp nor Mpfr have been built until then!

How is this supposed to work?

Thanks for your help!

Oliver

P.S. Above you have

-I/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.4.5_build/./gmp

which makes sense (gcc-4.4.5_build is the build directory), however gmp wasn't built, and we find

-I/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.4.5/gmp

which doesn't make sense since that contains only the source-distribution.

???

By the way, extracting the archives, resulting in

> ls gcc-4.4.5/gmp/
gmp-5.0.1
> ls gcc-4.4.5/mpfr/
mpfr-3.0.0

yields exactly the same error.
