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

[Patrick Alken]

Hello,

  It looks like its calculating the value correctly, but the test 
tolerance needs to be relaxed slightly. Can you locate this line in 
specfun/test_bessel.c:

 186   TEST_SF(s,  gsl_sf_bessel_j2_e, (1048576.0, &r), 
-3.1518539455252413111e-07, TEST_TOL3, GSL_SUCCESS);

and change the TEST_TOL3 to TEST_TOL4, and let me know if the test 
passes? If not try TEST_TOL5 and then TEST_TOL6, and tell me which one 
allows the test to pass.

Thanks,
Patrick
