I'm attempting to build bitcoin 0.12 on Ubuntu 14.04 LTS using the same configuration found here. 0.11 builds correctly.
```
configure: error: Qt dependencies not found
make: *** [config.status] Error 1
```

You are missing the Qt dependency. 0.12 uses Qt 5 instead of Qt 4 which was in previous versions. Follow the up to date instructions at https://github.com/bitcoin/bitcoin/blob/0.12/doc/build-unix.md to get a proper build.

Qt4 should work fine as it always has... this looks like a bug somewhere. @mkabatek Can you post config.log somewhere?

@luke-jr sorry I don't have the original config.log. I ended up installing the Qt 5 dependencies.

Then it complained about libevent-dev so I installed that now it appears to be building. Maybe 0.12 does not automatically fall back on Qt 4? I was also lacking libevent which looks like a change from 0.11. Sorry I can't provide more details I've mucked around with the system since I got stuck.

This indeed the case, and a known issue: #7189

As a workaround you can specify to build with qt4 specifically (--with-gui=qt4).
