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:

-------- Original Message -------- Subject: 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 Date: Fri, 1 Apr 2011 08:52:50 -0400 From: Aidan Van Dyk To: David C. Rankin CC: hfax

You'll want to apply this:

http://git.hylafax.org/HylaFAX?a=commitdiff;h=b0d873c950a72aa568d2fcfe7dbc8b...

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.

Guys,

I was working with hylafax in Arch updating the package from 6.0.4 to 6.0.5 and I ran into a strange error related to "throws different exceptions":

<snip> 86-64 -mtune=generic -O2 -pipe -c Dispatcher.c++ In file included from Sys.h:34:0, from Dispatcher.c++:27: /usr/include/sys/stat.h:299:47: error: declaration of ‘int fchmod(int, __mode_t) throw ()’ throws different exceptions ../port.h:32:12: error: from previous declaration ‘int fchmod(int, mode_t)’ make[3]: *** [Dispatcher.o] Error 1 make[3]: Leaving directory `/home/david/arch/pkg/bld/hylafax/src/hylafax-6.0.5/libhylafax' make[2]: *** [default] Error 2 make[2]: Leaving directory `/home/david/arch/pkg/bld/hylafax/src/hylafax-6.0.5/libhylafax' make[1]: *** [dirs] Error 2 make[1]: Leaving directory `/home/david/arch/pkg/bld/hylafax/src/hylafax-6.0.5' make: *** [default] Error 2 ==> ERROR: A failure occurred in build(). Aborting...

I'm getting better at sorting this stuff out, but exception handling problems are the exception... no pun intended. What says the experts. I wanted a clean install to look at permissions again on the bin/notify.php and bin/faxrcvd.php issue and thought I might as well try 6.0.5.

What say the experts? What is the probable cause of throwing different exceptions? The stat.h file on Arch is available on my server here:
