In any case, I figured out how to make this make file. I just go to lpng16 / scripts and I found many makefiles with file extension. I choose gcc because it is only familiar to me. I removed the name extension and placed it in a directory where I can find the headers and source files. I do not know why they do not include this instruction in the manual or it is simply hard to find there. (just a question about noob)
source share
