digitalmars.D.learn - Unable to get Phobos working on Ubuntu x64 (Oneiric)

I've just installed a new system - Ubuntu 11.10 beta x64 and can't get

When I try to compile file hello.d with the following content: 

import std.stdio;

void main()
{
    writeln("Hello World!");
}


I get this error:

Nothing else using Phobos compiles either.

I've seen previous related threads. Tried -L-lrt, didn't work.
I tried the .deb package for Ubuntu, the binaries shipped
in the source archive, as well as compiling Phobos myself (removing 
DMD/Phobos every time to make sure no files persisted), but nothing helped.


Has anyone encountered this problem? Did anyone get it to work on Ubuntu 
(especially 11.10)?

It's clearly an issue where it can't find librt, since clock_gettime is in 
librt. As long as you didn't mess with dmd.conf, -L-lrt should already be 
given to the compiler, but regardless, if you passed it yourself, it should 
work.

Are you using a 64-bit binary of dmd or a 32-bit binary? If you're using a 32-
bit binary (or building for 32-bit with a 64-bit binary), then you're going to 
need the 32-bit libraries for glibc, pthreads, and librt (I don't know what 
packages those are on Ubuntu, but if you have the 32-bit libraries installed 
at all, odds are that those ones are there).

I'm using the 64bit binary. DMD uses the following to link (from verbose 
output):

gcc hello.o -o hello -m64 -Xlinker -L/usr/lib64 -Xlinker -L/usr/lib32 -
Xlinker --no-warn-search-mismatch -Xlinker --export-dynamic -lrt -lphobos2 -
lpthread -lm

librt.so is present in /usr/lib/x86_64-linux-gnu , also copied it to 
/usr/lib . Still the same error.

librt.a is needed as well, so maybe that's the problem. /usr/lib/x86_64-linux-
gnu strikes me as a weird place to put it regardless. You should probably 
check whether it's in your linker's path. If so, it should be listed in 
/etc/ld.so.conf.

If librt.a is clearly in the linker's path, then I'd try just downloading the 
dmd zip file, unzipping it, adding /path/to/unzipped/dmd2/linux/bin/ to your 
path before wherever the installed dmd is (or adding it to your wherever in 
your path and uninstall the installed dmd) and seeing whether that works. I 
would hope that that wouldn't be necessary though.

But clearly, the linker is not finding librt, and that's what needs to be
fixed. 
I'm not an Ubuntu user though, so I don't know exactly what Ubuntu does 
differently or how dmd is installed with the .deb file. Personally, I've always 
use the zip file without trying to install dmd with the package manager or move 
any of its associated tools or libraries into /usr/ or /usr/local.

It's apparently not a problem with x64, since I'm using x86 Ubuntu. (I grabbed
the
wrong disk before I installed...)
I somehow have/had (I downgraded so I could work properly again) a /usr/lib64
folder. I'm not exactly an expert in Linux filesystems, or even anywhere near
close, but it seems that I shouldn't have had that on a x86 install. I had the
files librt.a and librt.so in there, but even desperately symlinking them into
the
proper location didn't help.
This problem is rather irritating - has anyone upgraded successfully, and
actually
had it work? I would definitely like to upgrade to 11.10, but I don't want to
have
to halt all code development when I do.
Thank you,

I tore my hair out over this before I examined the gcc line run by dmd, and 
found that -lphobos2 was being dropped in after -lrt. The simple fix is to 
modify your dmd.conf (build something with dmd -v to see where this is) such 
that "-L-lphobos2" is added BEFORE "-L-lrt".
