Re: [OMPI devel] Master warnings?

2018-06-03 Thread Gilles Gouaillardet

Nathan,

there could be another issue :

with gcc 8.1.0, I get some warnings (see logs at the end)

From 
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-error-function-attribute

error ("message")warning ("message")

If the error or warning attribute is used on a function declaration
and a call to such a function is not eliminated through dead code
elimination or other optimizations, an error or warning (respectively)
that includes message is diagnosed. This is useful for compile-time
checking, especially together with __builtin_constant_p and inline
functions where checking the inline function arguments is not possible
through extern char [(condition) ? 1 : -1]; tricks.

While it is possible to leave the function undefined and thus invoke a
link failure (to define the function with a message in .gnu.warning*
section), when using these attributes the problem is diagnosed earlier
and with exact location of the call even in presence of inline
functions or when not emitting debugging information.


Unlike the deprecated attribute, nothing is said about variables, so
based on the warning message, I guess the error attribute is only
allowed for functions (e.g. *not* on variables or typedef)

Cheers,

Gilles

No problem - I just commented because earlier in the week it had built clean, 
so I was surprised to get the flood.

This was with gcc 6.3.0, so not that old

Should have it fixed today or tomorrow. Guess I didn't have a sufficiently old 
gcc to catch this during testing.

Hi Ralph,

see my last comment in https://github.com/open-mpi/ompi/pull/5210

long story short, this is just a warning you can ignore.

If you are running on a CentOS 7 box

with the default GNU compiler, you can

opal_cv___attribute__error=0 configure ...

in order to get rid of these.

Cheers,

Gilles

Re: [OMPI devel] Master warnings

2017-06-13 Thread George Bosilca

e9d533e62ecb should fix these warnings. They are harmless, as we cannot be
reaching the context needed for them to have an impact because collectives
communications with 0 bytes are trimmed out in the MPI layer.

Thanks for reporting.
  George.
