D.gnu - Build script for a cross compiler

missing something or some issues like 32/64 bit mismatch.

This script gets the current head of gdc, loads the required gcc
version, pacthes it and configures for ARM. In addition, a file
to put in t-arm-elf is needed.

If you like, please test and report. If this is useful we may
then put this to wiki.

sudo apt-get install gcc g++ git libgmp-dev libmpfr-dev
libmpc-dev \
   binutils-dev flex

cd
rm -rf gdc
mkdir -p gdc
cd gdc


wget
ftp://ftp.funet.fi/pub/mirrors/ftp.gnu.org/pub/gnu/binutils/binutils-2.25.tar.gz
tar zxvf binutils-2.25.tar.gz
cd binutils-2.25
./configure --target=arm-eabi --disable-nls
make
sudo make install
cd ..


git clone git://github.com/D-Programming-GDC/GDC gdc
gccver=`cat gdc/gcc.version`
gccdir=`cat gdc/gcc.version | cut -c5-`


wget ftp://gcc.gnu.org/pub/gcc/snapshots/$gccdir/$gccver.tar.bz2
tar jxvf $gccver.tar.bz2


cd gdc

cd ..


cp  t-arm-elf.own  $gccver/gcc/config/arm/t-arm-elf



mkdir build-gcc
cd build-gcc
../$gccver/configure --target=arm-eabi --disable-bootstrap \
    --enable-languages=c --enable-multilib --disable-nls \
    --without-isl --without-cloog \
    --without-gmp --without-mpfr --without-mpc \
    --disable-libphobos

make
sudo make install

And this is what to put in t-arm.elf.own:
-------
MULTILIB_OPTIONS  += mcpu=cortex-m0/mcpu=cortex-m3/mcpu=cortex-m4
   mfloat-abi=hard mfpu=fpv4-sp-d16
MULTILIB_DIRNAMES += cortex-m0 cortex-m3 cortex-m4
MULTILIB_REQUIRED += mcpu=cortex-m0
MULTILIB_REQUIRED += mcpu=cortex-m3
MULTILIB_REQUIRED += mcpu=cortex-m4 /mfloat-abi=hard
/mfpu=fpv4-sp-d16
MULTILIB_EXTRA_OPTS += mthumb

I think that should be --enable-languages=d.  Is c necessary?

As an alternative (or if for some reason you are running an older OS),
rather than installing libgmp/mpfr/mpc through the repositories, you
can use ./contrib/download_prerequisites script in gcc sources.

I tried on Cubian (Debian variant for CubieBoard2), but it failed 
attempting to build gcc-6-20150412.



 git clone git://github.com/D-Programming-GDC/GDC gdc
 gccver=`cat gdc/gcc.version`
 gccdir=`cat gdc/gcc.version | cut -c5-`


Note: If checking out gdc-4.9, this does not use the latest build.
Instead you will get gcc-4.9.0, which is buggy and absolutely not 
recommended.



 cd gdc



The last line should of course be enabled. ;)



 cp  t-arm-elf.own  $gccver/gcc/config/arm/t-arm-elf




{snip}

 make


make fails on my CubieBoard2. These are the last lines I see:

(Note: I did not press control-C; the script terminated by itself)

It seems I can't build any GCC (not even a native GCC without 
GDC) on CubieBoard2.
-So I expect I'm missing some tools.
I do have flex, bison, autotools and libtool installed; and I 
also have gmp/mpc/mpfr, so it must be something else.

I've polished my own build-script/build-instructions. So far, 
this is the only thing that will work on a PowerMac with Mac OS 
X. It does not work on Cubian. It does not work on Debian. It 
*might* work on Mac OS X with intel, but I do not know.
My build-script/instructions will result in a toolchain 
supporting C/C++/D AND stdlibc++.
Thus I can now finally build my old projects AND have D at the 
same time; no compromises (except from that the compiler is only 
built once, not twice, but that's considered acceptable).

Even though my guide will not work out-of-the-box on Linux or 
other systems, it might serve as an approximate how-to / way to 
get past problems (I've got 5 years of experience in making ARM 
toolchains).

http://d.gpio.dk/dl/Build%20a%20GDC%20toolchain.pdf

If using the script (or using the guide as a script), 3 optional 
parameters can be supplied:
1: workdir (a temporary directory for containing sources and 
builds).
2: prefix: For instance /usr/local - default is to install in 
$workdir/Install
3: toolchain name; If building a package, this will be appended 
to prefix: /usr/local/myTools
