Successful GDC 4.8 build on Ubuntu 12.10

[Joseph Rushton Wakeling]

Hello all,

This morning I managed a successful build of the latest dev GDC, so I thought 
I'd give a brief writeup.

Let's assume that the GDC sources are cloned into $SOMEDIR/gdc/dev

     (i) Download gcc-snapshot sources with apt-get source gcc-snapshot.
         I downloaded them into $SOMEDIR/gdc so that the actual source is
         contained in gdc/gcc-snapshot-20121008/

    (ii) cd gcc-snapshot-20121008 and edit debian/rules.patch to comment out
         the line "debian_patches += gcc-d-lang"

   (iii) Run debian/rules clean and debian/rules patch

    (iv) cd ../dev/  (i.e. to GDC source dir) and run
         ./setup-gcc.sh ../gcc-snapshot-20121008

     (v) cd ..; mkdir objdir; cd objdir

    (vi) ../gcc-snapshot-20121008/src/configure --enable-languages=d 
--disable-multilib --disable-libgomp --disable-libmudflap --disable-libquadmath 
--disable-libquadmath-support --disable-bootstrap --enable-checking=release 
--prefix=/opt/gdc --disable-nls

        (This is the configure setup I used, others may work:-)


   (vii) make -j4 2>&1 | tee build.log

  (viii) sudo make install

Hooray, hooray, O Frabjous Day and all that. :-D

Best wishes,

     -- Joe
