OK, I won't do that anymore. ;)
Just a note: That was something I found on the net recently for a 4.5.3.

I have a bash-function, which (usually) does the following for GMP, MPFR and
MPC; they're all treated the same way:
# create build directory and cd into it...
mkdir -p "$BUILDDIR/$NAME-$VERSION"
cd "$BUILDDIR/$NAME-$VERSION"
# configure and build library
$SOURCEDIR/configure --quiet ABI=32
--prefix="/Users/toolchain/avr-toolchain/packages/gmp/usr/local/myPkg" $WITH
make
make install
ln -s "$SOURCEDIR/$GMP" "$SOURCEDIR/$GCC/$NAME"
export CFLAGS="$CFLAGS -I$SOURCEDIR/$NAME-$VERSION"
export LDFLAGS="$LDFLAGS -L$PREFIX/lib"
export LD_LIBRARY_PATH="$PREFIX/lib:$LD_LIBRARY_PATH"
WITH="$WITH --with-$NAME=$PREFIX"
CC is set to "gcc -m32"
$WITH adds the library's prefix path after it's compiled, so when GMP is
compiled, MPFR gets a...
--with-gmp=/Users/toolchain/avr-toolchain/packages/gmp/usr/local/myPkg
$NAME is one of the following: gmp, mpfr or mpc
$VERSION is one of the following: 5.0.2, 3.0.1 or 0.9
$GCC is for instance gcc-4.5.3
Note: Before every build, I remove the build directory and install directory,
just to be sure that I get a clean install.
Now and then I even remove the source directory as well.
(I don't even use make clean here; learned from experience).
However, that doesn't work either. Are my CFLAGS, LDFLAGS and LD_LIBRARY_PATHs
correct ?
As far as I understand, when reading
<http://gcc.gnu.org/install/configure.html>, the --with-(library)= should be
set to the path of the installed gmp/mpfr/mpc. Is this setting correct ?
Love,
Jens
