libdevil compiles fine for me. If the problem only appears when "running code dependent on libdevil", can you provide an example of this that I could use as a test case?

Same here, libdevil compiles fine, which makes little sense to me, since il_png.c includes "png.h" in order to call the old "png_set_gray_1_2_4_to_8", while "png.h" no longer references this method (other than in the comments where they say it's been deprecated and replaced by the other one). Could there be another (outdated) png.h outside MacPorts on Mac OS ? Haven't got an easy sample code right here, but a simple use case would be to call the {{{ILboolean readpng_get_image(ILdouble display_exponent)}}} function, which calls "png_set_gray_1_2_4_to_8" (line 281 of il_png.c) in the specific case that your input PNG file is grayscale and has less than 8bit precision. -- Ticket URL: <https://trac.macports.org/ticket/29749#comment:4> MacPorts <http://www.macports.org/> Ports system for Mac OS

But before I would commit such a patch, I would want to verify the issue, and verify the patch fixes it. That means I need a set of commands I can type in my terminal that demonstrate the problem. I am not a C programmer; if you are, can you supply a program that calls this function you mentioned, and instructions on how to compile and use it? Regarding the specific type of input file you suggest using with it, can you supply such an image? -- Ticket URL: <https://trac.macports.org/ticket/29749#comment:6> MacPorts <http://www.macports.org/> Ports system for Mac OS
