I am trying to install libpng on a CentOS machine and getting some FAIL messages when running: make check. uname -a: Linux clusterhn.cluster.com 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux Using: ./configure --prefix=/opt/software/grib2 make check This happens when I try to check both libpng-1.6.34 and other versions. Using Intel compilers. Any suggestions? -- *Scott Capps* Principal Atmospheric Data Solutions <http://www.atmosphericdatasolutions.com> [email protected] cell: (949) 910-4385 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ png-mng-implement mailing list png-mng-implement-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org https://lists.sourceforge.net/lists/listinfo/png-mng-implement

The error is calculated as the difference between the output pixel value (always an integer) and the ideal value from the libpng specification (typically not an integer). Expect this value to be less than .5 for 8 bit formats, less than 1 for formats with fewer than 8 bits and a small number (typically less than 5) for the 16 bit formats. For performance reasons the value for 16 bit formats increases when the image file includes an sBIT chunk.
