I tried downloading tango beta .95 and get it to install both under my gdc installation and dmd installation.  Both failed miserablly using lib/install-dmd.sh and lib/install-gdc.sh

From the dmd installation it bombed here:
gcc -c -O -m32 critical.c -ocritical.o
dmd -c -release -O -inline -version=Posix -w deh2.d -ofdeh2.o
dmd -c -release -O -inline -version=Posix -w dmain2.d -ofdmain2.o
dmd -c -release -O -inline -version=Posix -w genobj.d -ofgenobj.o
dmd: toobj.c:315: virtual void ClassDeclaration::toObjFile(): Assertion `classinfo->structsize == 0x3C' failed.
make[1]: *** [genobj.o] Aborted
make[1]: Leaving directory `/usr/local/src/tango/lib/compiler/dmd'

From the gdc installation it never would generate libtango.o in the lib directory.

Has anyone else successfully installed Tango?

Tango has a 1004 compatible runtime component. That particular assertion problem is a mismatch between the 1004 runtime and a pre-1004 compiler (dmd 1.0?). It's effectively the same thing as if you ran a dmd 1.0 with a phobos 1004 :)

Hope that gets you going again!

p.s. there's also forums at Tango which generally get a very quick response. The IRC channel is usually immediate, if you have an IRC client. All noted here: http://www.dsource.org/projects/tango/wiki/Contact

As kris said, the 'object' module for Tango seems to assume DMD 1.004 if you're using DMD.
You could try commenting out the 'OffsetTypeInfo[] offTi;' line in the ClassInfo declaration, that seems to be the change that leads to that assertion. I'm not sure if there were any other significant changes though. Or you could, you know, upgrade DMD ;).

If Tango requires DMD 1.004+, I think it should say so on the relevant web page(s), such as one or more of these:

http://www.dsource.org/projects/tango/wiki/Download
http://www.dsource.org/projects/tango/wiki/TopicBuildingTango
http://www.dsource.org/projects/tango/wiki/TopicInstallTango

If it's already mentioned in bunch of other places, I'm sorry I missed them.

The GDC issue is my fault, I missed something in the installer.

Just `touch libtango.a`, it's not supposed to exist anyway.

From the download page: "The runtime portion of this release requires a v1.004 compatible compiler."

Actually, that's just if you compiler actually *is* DMD, I think. In object.d, it has the v1.004 modification in a version(DigitalMars), so I think it'll probably break if used with a v1.004-compatible GDC...
(Presumably this was done because GDC isn't v1.004-compatible yet?)

You're right about this of course :) I'll fix it soonish. Thanks!

David updated it yesterday. The gdc-0.22-dev branch in svn is up to 1.004.

Thanks for all of the comments on both DMD and GDC - I didn't have the latest and greatest DMD so I moved it to the side and let the Tango installer take care of it.  All is well now.  Except for converting everything in my code :-)
