Where is the right place?
What OS are you running?
Ubuntu 12.04
Ahh, OK. What GCC source are you attempting to build from? I think that 4.7
(which lacks multiarch support) is probably not worth building against any more.
I did try building against 4.7 from the deb-src package, ages ago, but I don't
think I ever got it working. I _did_ get it working from the source of the
gcc-snapshot package, but I'd advise against that.
I've built successfully on a 12.04 install (a university cluster) using the
4.8.1 sources (haven't updated it recently as I've been running everything on my
local machine), downloaded directly from gcc.gnu.org; now, of course, you'll
want 4.8.2, which should also work fine.
Supposing that you're using $SOMEDIR/gdc to store everything, a rough
description of the procedure would be:
* Clone GDC master into gdc/dev
* Unzip the GCC source into gdc, which will give you a subdirectory
called gcc-$VERSION (currently gcc-4.8.2)
* cd into gdc/dev and run ./setup-gcc.sh ../gcc-4.8.2
* cd back into gdc, create gdc/objdir, cd gdc/objdir
* Run configure and make.
Here's how I like to run configure for a release build:
../gcc-4.8.2/configure --enable-languages=d --disable-multilib
--enable-multiarch --enable-checking=release --prefix=/opt/gdc
You can miss off the --enable-multiarch -- which will also probably speed up
your build time.
With this you shouldn't need to custom-set CPATH or LPATH. Does it work for
you?
