Dear GSL Developers, Version of GSL : 2.1 (Stable version) downloaded from ftp://ftp.gnu.org/gnu/gsl
Hardware & Operating System : Intel Core i5, 3.2 GHz Ubuntu 12.04.3 LTS Compiler used, including version number gcc, version 4.6 used to compile the GSL source code Description of the bug behaviour : Was trying out the gsl-randist using the given example in the GSL documentation $ gsl-randist 0 10000 cauchy 30 | sort -g | gsl-histogram -1e6 180000 1000 This gives an error : gsl-histogram : invalid option -- '1' Usage : gsl-histogram [-u] xmin xmax [n] Computes a histogram of the data on stdin using n bins from xmin to xmax. If n is unspecified then bins of integer width are used. If -u is given, histogram is normalized so that sum of all bins is unity. BUG: The bug seems to be that the gsl-histogram is unable to take negative values to "xmin" and is therefore thinking that "-1" from -1e6 is an option and hence printing out the error. The same error is not given by GSL 1.15 where the -u option doesn't seem to be there. *--* *Thanks & Regards,* *Aaditya Majalee*
