Well, sure. For development is what I'm talking about. Overriding the default flags is pretty easy if you want to do that for whatever reason, though and I won't even pretend to care if you do. I just assumed the default was what we were talking about. Or do we have something scary going on in our setup that makes this non-trivial that I'm glossing over? <div class="gmail_quote">On 28 May 2014 20:20, "Robin Sonefors" <<a href="mailto:ozamosi@flukkost.nu">ozamosi@flukkost.nu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> On 2014-05-28 19:13, Anton Löfgren wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi, The right thing to do would be to check the return value, so I vote that we do that.

Warnings are warnings rather than errors because they are not, in fact, errors. Errors, on the other hand, are errors, which makes them different from warnings. -Werror is a simple way to say "break this very simple concept". There's a ton of compilers and compiler versions and things they might or might not warn for - correctly or incorrectly[0] - before doing the right thing anyway: it was a warning, not an error, after all. Guaranteeing that nobody will see a warning is hard and boring, and -Werror antagonizes compiler developers who add new and helpful checks. For development, we should always strive to build with (and make it hard to disable) as many of -Wall -Wextra -Werror -pedantic -fstack-protector-all \ -D_FORTIFY_SOURCE=2 -Deasy-mode -fhelp-me-please as possible, because writing C is hard, and I most certainly don't trust myself to do it unassisted. However, it's hard to resist the argument that tarballs intended for public consumption should probably try to do what said public want to them to, i.e. build and work. [0] Compilers are buggy, too. While in this case, the compiler is right, I remember when code I wrote failed to build with -Werror due to <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36750" target="_blank">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36750</a> where GCC'd warn that my code followed the standard and suffered from no undefined behavior whatsoever - gee, thanks. <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> On 28 May 2014 17:46, "LAHAYE Olivier" <<a href="mailto:olivier.lahaye@cea.fr" target="_blank">olivier.lahaye@cea.fr</a> <mailto:<a href="mailto:olivier.lahaye@cea.fr" target="_blank">olivier.lahaye@cea.fr</a>>> wrote: Hi, I'm a developper of the OSCAR Cluster opensource software and I4m in the process of integrating naemon in se supported things that can be configured from the cluster install wizard.
