Dear Mr President,

I went to the source code here: http://code.qt.io/cgit/qt-creator/qt-creator.git/tree/README.md
and it says

    ## Compiling Qt Creator
    * Qt 5.9.0 or later
     [...]
    * On Linux: g++ 5.3 or later

So what you found is true, but only part of the truth. std::enable_if_t
is C++11, and that's officially required to build Qt Creator since 2014.
gcc 4.8.4 was good enough until 2017, i.e. has been given a grace period
of more than two years.


Even if the version requirement for gcc weren't documented please note
that the relation 'can-be-build-with' is not transitive.

"Creator version X can be build with Qt version Y" and "Qt version Y can be
build on OS version Z" does not imply "Creator version X can be build
out-of-the-box on OS version Z".

Please note also that "not out-of-the-box" does not necessarily mean it 
cannot be done.  Asking Google for "ubuntu 14.04 gcc" gives as third hit
https://gist.github.com/application2000/73fd6f4bf1be6600a2cf9f56315a2d91,
apparently giving instructions to get a gcc 6.1 on Ubuntu 14.04.
