png.h file not found - Linux

For centOS 7 you can try

yum -y install libpng* 

try rather this:

sudo apt-get install libpng-dev

Then maybe go askubuntu.com ;)

With Ubuntu 18, /usr/include/png.h moved to /usr/include/libpng/png.h A workaround is this: ln -s /usr/include/libpng/png.h /usr/include/png.h

Or you can configure your build to use include directory /usr/include/libpng
