So I tried building Tango trunk a while ago, and it actually built surprisingly well, with only one small error I was able to fix. So I installed the tango library and proceeded to test if tango was really working. So in hello.d:

import tango.io.Stdout;
void main(){ Stdout("Hello {}!","World").newline; }

I don't know why, but I had to manually add object.d to the command line. To simplify, I put an object file of object.d into the current directory.

tests% gdc -o hello hello.d object.o -lgtango -lgphobos
ld: duplicate symbol __D6object9Interface6__initZ in /usr/local/lib/libgphobos.a(object.o) and object.o
collect2: ld returned 1 exit status

I'm not sure if this problem is an issue with gdc or a problem with Tango. Any ideas on how to fix this?

http://www.dsource.org/projects/tango/wiki/UnixInstallGdc Have you looked there?

Yes, that is the main page I used when I was trying to figure out how to install Tango. As far as I can tell I did everything right. Like I said, this could be a problem with the new version of Tango, possibly just because the dmd frontend version isn't what Tango is set up for. Unfortunately, the 0.99.8 release had a lot of problems with gdc, so I'm just trying to get the trunk working.

Should I try posting this to the main digitalmars.D group?

Sure. You'll probably get much more answers there.
