What is the last command to fail when you run 'm= ake V=3D1'? 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 be= low=20 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
