Thanks for the heads-up. What is the last command to fail when you run 'make
V=1'?
Also, in src/Makefile, what are the values of PNG_CFLAGS, and of LIBIMAGE?
Also, what is the output of the following shell commands? (The session below
shows the output on Fedora 27.) Is the output correct for Arch Linux?
$ pkg-config --cflags libpng
-I/usr/include/libpng16
$ pkg-config --libs libpng
-lpng16 -lz
$ libpng-config --cflags
-I/usr/include/libpng16
$ libpng-config --ldflags
-L/usr/lib64 -lpng16
