Compile Error about jiffy HOT 13 CLOSED

Interesting. Must be a new warning. Can you check if there's an option to silence that particular warning?

In a pinch, removing -Werror in rebar.config will let you compile.

Ah, its a known bug:

https://code.google.com/p/double-conversion/issues/detail?id=37

Will keep an eye for a fix.

@BFrog Can you try compiling master on GCC 4.8? I pulled a suggestion from the V8 bug but I don't have 4.8 handy to try it on.

from jiffy.

I'm getting the same warning/error on compile under gcc-4.8.

from jiffy.

@gar1t Are you using a tag or master? If you're not on master can you give it a test to see if my fix works? I don't have 4.8 handy to test myself.

@rkakrik Is that with master?

from jiffy.

Yep.

from jiffy.

Tried to 'rm -r jiffy && git clone' - but the same result

from jiffy.

@rkakrik @gar1t @BFrog Just had a patch submitted pointing out I had a typo in the compiler directive thing to disable the warning. Let me know if any of you can give the latest master a whirl on GCC 4.8.

from jiffy.

Good grief - shame on me and everyone here for not spotting this one :)

Work great - thanks!

from jiffy.

There's actually another warning coming up on gcc 4.8.1. I'll open another ticket as it's a different problem.

from jiffy.

Sounds like this one is fixed. Closing and tracking the next 4.8 issue in #45
