[gentoo-user] D and Gentoo

[Elias Diem]

Hi all

What's the best way to have a D compiler in Gentoo?

I know that there is a USE flag for gcc which adds D, but 
apparently it doesn't work.

Hi=) There's Digital Mars D Compiler (dev-lang/dmd) at sunrise overlay,
latest is 2.063.2, it's compilable and seems to be working =)

I know absolutely nothing about D, which makes me qualified to ask
how you can tell if the 'd' useflag is working or not ;)

Hehe. Good question.

Well I enabled this USE flag for gcc but I don't have an 
executable that starts with

gcc...
gdc...

And furthermore if I run 'equery u gcc' there is no d USE 
flag. It's not even there to tell me that gcc was compiled 
without it!

Hi Elias,

According to 'euse -i d', the 'd' flag only shows up for
'=sys-devel/gcc-3.4.6-r2' and '=sys-devel/gcc-4.1.2'. I'm assuming you
are using a newer version of gcc that doesn't have the d use flag.

My sugesstion would be to look for a portage overlay that has the D
compiler. Anton mentioned the Digital Mars D Compiler (dev-lang/dmd) at
sunrise overlay, so you might want to take a look at that. A quick
search also showed a wiki page on ldc [1], although I'm not sure how
reliable/legit it is.

Regards,
Pavel

Indeed. Thank you for the explanation.

Hi there

Just for the records.

I finally managed to build GCC with D support myself 
(without using the overlay).

What I did:

- Download and enpack a tar for GCC 4.8.2

- Clone the git repo from gdcproject.org

- Check out the appropriate branch in the git repo

- Run the setup-gcc.sh script

- Configure GCC (including --enable-languages=d)

- Make GCC
