Hi Sorry if this is not really related 100%.

I'm trying flymake today (because in master branch flycheck today
started freezing emacs, but that's another issue).

And I just opened a file with simple compilation errors 

emacs -Q myfile.cpp
M-x flymake-mode

And I see no errors detected. I tried many things and
flymake-running-backends prints.

Running backends:

And show-diagnostics says there are not diagnostics.

```
#include <unexistenfile.h>

nit var;

function() {
        tt;
        var1 = 23as;
}

```

Do I am missing something? Probably it needs some extra configuration,
or external dependency?

When I try to compile this code I get (as expected):

-----------------------
-*- mode: compilation; default-directory: "~/borrar/" -*-

g++ lower_bounds.cpp -o lower_bounds.x

      |          ^~~~~~~~~~~~~~~~~
compilation terminated.

Compilation exited abnormally with code 1 at Wed Jun 26 17:56:42
-----------------------

How can I check whats missing in my system?
