D.gnu - Packaging GDC

Hi!

I'm working on packaging GDC for openSUSE, and I have a few 
questions.

Is it possible to make the build process install only D related 
files, for example cc1d, but not cc1?

If the above works (or I manually exclude generic GCC files from 
the package), will the D specific binaries be compatible with 
generic GCC binaries/libs from other GCC versions?

I'm asking this because I'd rather not have to make the GDC 
package depend on the distribution's default GCC packages, 
because then I would have to match the GCC versions across the 
different openSUSE versions...

Any hints?

1)

About not having gcc as dependency - no, as far as I have 
understood so far, gcc backend is not designed not be used as 
library for building independent compilers, it only works as a 
platform which provides set of supported languages. There are 
plenty of shared libraries/tools between different gcc-based 
compilers which would conflict if installed all together.

And using different gcc version from distribution default gcc is 
a good way to screw people systems in a very hideous ways :)

2)

However if you do use the same base GCC version as existing 
distro gcc there is no need to package common stuff like cc1 (it 
would conflict) - you can only package D additions and specify 
system gcc package as dependency.

This is what I do on Arch Linux:
https://projects.archlinux.org/svntogit/community.git/tree/trunk?h=packages/gdc
(see PKGBUILD for bash script which builds/packages stuff)

As you can see actual GDC essentials come down to this:

install -D -m755 $srcdir/gcc-build/gcc/gdc $pkgdir/usr/bin/gdc
install -D -m755 $srcdir/gcc-build/gcc/cc1d 
$pkgdir/usr/lib/gcc/$CHOST/$pkgver/cc1d
install -D -m755 $srcdir/GDMD/dmd-script $pkgdir/usr/bin/gdmd

Ok, I guess I will have to use the same GCC versions as the base 
distro, and try to match their configuration as closely as 
possible, to avoid incompatibilities.

Thanks for this! That's actually a nice idea not to call `make 
install`, but instead package the compiled files directly. I'll 
have to try this, should make things a bit easier compared to 
deleting all the unwanted files.
