Do you have an example?

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/" -*-
Compilation started at Wed Jun 26 17:56:42

g++ lower_bounds.cpp -o lower_bounds.x
lower_bounds.cpp:1:10: fatal error: unexistenfile.h: No such file or directory
    1 | #include <unexistenfile.h>
      |          ^~~~~~~~~~~~~~~~~
compilation terminated.

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

How can I check whats missing in my system?

It's 100% unrelated.

First of all, you just look at the value of flymake-diagnostic-functions.

Apparently, c++-mode uses flymake-cc.

You might want to go ahead and read it, but it's a minimalistic solution 
that relies on Make and a particular target being present (see 
flymake-cc-use-special-make-target). Would I be correct in assuming that 
you don't have it?

Flycheck probably has more sophisticated checkers, but the new Flymake 
API is not too hard. You should be able to port whatever checker you 
have been using to Flymake without too much difficulty.

I forgot to tell that the Flymake log says:

Hi, sorry, where is all that documented? Specially how to make the
target in this case and the flymake api specifications?

The Flymake manual.

Check out

   git show 9a0b20d5b33

as well as

   doc/misc/flymake.texi (or whatever manual gets compiled from it)

You could have found the latter with 'ag check-syntax', by the way.

> and the flymake api specifications?

flymake-diagnostic-functions's docstring. Or the manual, I guess.

I think it's just the flymake tests in general; https://debbugs.gnu.org/32764 .

I don't know of any reason why this would be specific to hydra.nixos.org.

Joao pushed general Flymake fixes yesterday. Should we try and re-enable 
them?

Yeah, I wonder how I'm not seeing similar ruby-backend or perl-backend 
related failures on EMBA. Though maybe the executables are not available 
there, and somehow the log doesn't mention that they were skipped.

I had them in some computer for a while. I do believe they were related to
some tests breaking, not sure which.

Anyway, I'm just reading these messages now on my phone. I'm very thankful
for the attention you are giving this and apologize for being such an
absent maintainer. There's a lot on my plate right now. If there's
interest, i'd be glad to share maintainership of Flymake in emacs (if
that's not what's happening already anyway). I almost never read them these
days but I think there are some reasonably sane ideas in the bug tracker
that just need someone with a little time and a keen eye for emacs
practices to review and approve.

Just trying to keep bits and pieces from falling apart. I don't have a 
lot of free time myself either these days, but I'll see if I get around 
to those someday.

Not sure what particular ideas you're referring to, though. I read the 
bug tracker fairly regularly, and no particular bug report comes to mind.

Same failure happened:

Thank to the magic of not doing anything (right?), it seems the flymake 
failures are not there anymore.

The recent builds fail beacuse of shadowfile tests and, intermittently, 
something to do with autorevert.

FTR, both I'm working on, with slow progress.

Best regards, Michael.
