digitalmars.D - Tango ready?

 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

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.

 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?)

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 :-)

Then I'm willing to bet it won't work with current Tango unless it for 
some weird reason defines version=DigitalMars when parsing module 'object'.
If I'm right, one of the error messages will be similar to "toobj.c:417: 
virtual void ClassDeclaration::toObjFile(): Assertion 
`classinfo->structsize == (0x3C+8)' failed." (that's the error DMD gave 
me when I tried to compile with an old object.d, with the line number 
changed to where the assertion is in the current gdc-0.22-dev branch)

Tango's 'object' module is littered with version(DigitalMars) blocks to 
select stuff that changed in v1.004, and which the new gdc presumably 
will need as well.

So in fact the current Tango release requires DMD v1.004 or GDC 0.21. 
Earlier GDC versions may also work if it's runtime-compatible, but 
that's about the extent of Tango portability between compilers at the 
moment.

Yes, we cannot require the user to use a compiler from SVN, neither update
our codebase on it (if for nothing else than mantainance reasons). So the
latest release needs GDC 0.21, and the Tango svn will not be updated until
0.22 is officially released.

We may host contributed patches for those who want to follow the bleeding
edge at all times, though.

If only std.compiler was kept up-to-date, then you could just use static 
if conditions on the compiler version to automatically select the 
correct version...
(Assuming the circular dependency won't be a problem)


Of course, I use DMD anyway so I'm not personally affected by this.

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 ;).
