I am installing libpng using Intel compilers on a CentOS machine. I can't get it to pass all of the tests. CentOS 7.xx Linux 64 Bit Operating System Xeon 5115 Scalable Cloud Ready Processor Cores / 2.4 GHz I have tried many latest versions including 1.6.34. Attached is the test-suite.log. Thank you. -- *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.
