Can't make on Ubuntu 16.04

[pixelastic]

Hello,

I've just tried to run make in the freshly cloned dssim directory but was greeted with the following answer:

make

I think I have all the needed dependencies installed, but have no idea how to move forward from here. Thanks for any help.

✔ libpng12-dev  1.2.54-1ubuntu1
✔ zlib1g-dev      1:1.2.8.dfsg-2ubuntu4
✔ pkg-config      0.29.1-0ubuntu1
✔ make             4.1-6

libpng 1.2 is ancient. Can you use libpng 1.6?

[pixelastic]

Thanks, I just installed libpng16-dev and make succeeded. Apparently libpng12 ships with Ubuntu 16.04.

Unfortunately, installing libpng16-dev causes libpng12-dev to be removed, and anything depending on it (including libfreetype6-dev and libgtk-3-dev).

The Rust version doesn't have this problem. Build with cargo build --release.

For anyone else who's trying to build this for Ubuntu 16.04 and comes across this:

make CFLAGS='-DPNG_SKIP_SETJMP_CHECK'
