D.gnu - DSSS install of gdc-gcc-4.1 fails on OS X

Following the advice in the tutorial videos on the DSSS page, I ran 
"dsss net install gdc-gcc-4.1" to get a fresh install of gdc on my 
machine. It downloaded and compiled a bunch of stuff, but then errored out:

Is this a known issue on OS X? Is installing gdc using DSSS only 
supported under Linux? If this problem is something new, I'll be happy 
to provide any information that'll help diagnose the problem; just let 
me know what's useful.

Also, I note with some suspicion that it thinks it's building for the 
i386 architecture, when in fact it should be i686 -- probably not a huge 
difference but I assume the i686 target would generate different code to 
take advantage of new instructions, etc. I'm happy to live with i386 for 
now if I can get it to work at all.

I had previously downloaded an OS X installer for gdc, which worked (and 
is how I got a DSSS binary) but it installed itself in /usr and I'd 
rather install in a user account for now so I can easily package up the 
environment and copy it to other machines.

Thanks for any advice anyone can give me!

FSF GCC has several issues on Mac OS X, this might be one of them ?
The regular builds of GDC instead uses the Apple GCC, e.g. gcc-5363.

The Apple build does --with-arch=nocona --with-tune=generic
for i686, the platform has been arch i686 since Mac OS X 10.4
(Intel Darwin version 7 and earlier instead used arch i386)
Probably doesn't make a huge difference, just like you say.

Beyond the fact that you can install it to a different prefix,
you can get the tarball version at http://dgcc.sourceforge.net/

I had tried specifying an alternate prefix from the installer, but gdc 
didn't work; when I tried to compile anything, I'd get

object.d: module object cannot read file 'object.d'

I just tried again, ran gdc under ktrace (OS X's strace equivalent, more 
or less) and tracked down the problem: the installer needs to create an 
additional directory when you're not installing in /usr.

$ mkdir -p <install base>/lib/gcc/i686-apple-darwin8/4.0.1

fixed the problem for me. The root cause is that gdc uses 
<prefix>/lib/gcc/i686-apple-darwin8/4.0.1/../../../../include/d/4.0.1 as 
the default include directory; if the directory structure under /lib 
doesn't exist, it can't find its include files. If you install in /usr, 
that directory already exists, so everything works.

Will file a bug against the Mac GDC project, but hopefully this will 
help anyone who finds my original bug report via a search engine or 
whatever.

Right you are, those directories already existed here (from another 
installation) when I tried it. It'll be added to the 0.25 postflight...

Hi Steven,

I am having the same issue as you did when installing gdc using dsss. I'm
extremely new to D. I have gdc installed from the dmg, but was trying to get the
whole dsss thing to work. Can you quickly explain what you changed to get it to
work on OSX?

Thanks
