[arch-general] Fwd: Re: [hylafax-users] Error building 6.0.5 on Arch Linux /sys/stat.h:299:47: error: declaration of ‘int fchmod(int, __mode_t) throw ()’ throws different exceptions

[David C. Rankin]

Just FYI Arch Devs - Hylafax needs a patch to build with gcc 4.5. You may want 
to wait for 6.0.6 for the next version update. Details from the ifax devs below:

You'll want to apply this:
 
http://git.hylafax.org/HylaFAX?a=commitdiff;h=b0d873c950a72aa568d2fcfe7dbc8bb6e981c129

I still believe this is a bug in GCC 4.5+, where they turned something
every other compiler handles a fatal error, causing configure not to
find the declaration for fchmod (and thus declare it's own in port.h).
  I doubt anyone will be able to convince GCC of this ;-)  See:
     http://bugs.hylafax.org/show_bug.cgi?id=924

configure has been changed in HylaFAX to not tickle that particular
property of GCC.

That fix was applied to the 6.0 branch after 6.0.5 was released, but
no distros were based on GCC 4.5+ yet at that time.

I guess it's time for 6.0.6 release...
a.
