I'm getting

Hmm, could you please update your GCC? The to_string method I am using here is part of C++11. This should be supported by the current GCC version.

larskotthoff commented 9 years ago

This is on our cluster, so updating GCC isn't something that can be done easily.

jakobbossek commented 9 years ago

Ok, so the only possibility is another integer to string conversion method. Going to check this in about an hour, ok?

larskotthoff commented 9 years ago

Sure, there's no rush -- plenty of other things to run until then.

jakobbossek commented 9 years ago

The function now uses the old way of double to string conversion. Hopefully, I do not use more C++11 stuff.

larskotthoff commented 9 years ago

Thanks, compiles for me now.
