I am trying to use Tango in a dub project because I need a HashSet. I added Tango as a dependency to the dub.json, but now dub gives me a bunch of depreciation warnings and a few errors, like

../../../.dub/packages/tango-1.0.3_2.068/tango/tango/util/log/Log.d(349,51): Error: undefined identifier '__va_argsave', did you mean struct '__va_argsave_t'?

What am I missing?

It might not be compatible with that version of the compiler. Or are you using something that is not DMD?

Since I just do "dub build", I assume it invokes dmd? I have v2.072.0.

Try an older version.

I thought Tango was obsolete a long time ago.

Is there a specific reason you need to use Tango and can't use Phobos?

I need a Set implementation and from what I understand there isn't one in Phobos right now?

Have you seen https://github.com/economicmodeling/containers it has a HashSet http://economicmodeling.github.io/containers/containers/hashset.HashSet.html

Before resorting to that, I am also trying to "dub build --compiler=gdc". Getting different types of errors:

../../../.dub/packages/tango-1.0.3_2.068/tango/tango/math/IEEE.d:614:17: error: instead of C-style syntax, use D-style syntax 'real[3][] vals' [-Werror]
     static real vals[][3] = // x,frexp,exp
...
                                  ^
cc1d: all warnings being treated as errors

I tried to suppress the errors by adding buildRequirements:["allowWarnings", "silenceWarnings"] to dub.json, but no luck. Is it possible to get around them?

I don't know. Seems like the -Werror flag is passed, somewhere.

It's a third party library like any other library.
