I was building one example of DLangUi (dub build 
--build-mode=allAtOnce --build=debuglinker) and it did compile 
but the linker started to complain. I did notice it seemed to be 
related to the standard library, so I updated it and DRuntime to 
the lastest master, rebuilt them and replaced phobos.lib with the 
result. I also removed the binary and .dub directory from DLangUI 
to force Dub to rebuild it, which it did. Still the linker 
complains, but about a different symbol:

..\..\lib\dlangui.lib(colors)
  Error 42: Symbol Undefined __d_switch_string

Does anybody have an idea what could be causing this?

The deps have to be rebuild too. Assuming paths and everything is 
okay (should be the case when you build ~master as indicated in 
the wiki) just add --force.

After downloading dmd 78, it started to work. It's likely you 
were right about the issue, DUB rebuilt everything after 
detecting new compiler version.

Sorry for my late reply.

 From a compiler version to another, the ABI can change (examples 
are: mangling, new overloads as seen with format a couple of 
months ago). You compiled the program with a slightly different 
ABI than the one used to compile the deps as static libraries.

I don't know why DUB didn't detect this but as said user1234 
always try " --force" on DUB or rebuild deps manually to 
eliminate this possible cause of problems.
