Re: [Help-gsl] GSL 2.4 make check failing on Rocks cluster running CentOS 6.9

[Patrick Alken]

Ah so it looks like the problem is with the internally estimated error, 
which is quite wrong for this input value. I will need to think about a 
fix for this, and I will open a bug report to track the issue.

In the meantime, don't worry about this error since it is calculating 
the correct value to within 14 decimal places.

You can run make -k to test the rest of the library (-k won't quit when 
it encounters an error). Can you let me know if you find any more failures?

Thanks,
Patrick
