Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: aztecs-sdl-text-0.6.0 (user goal)
[__1] next goal: sdl2-ttf (dependency of aztecs-sdl-text)
[__1] rejecting: sdl2-ttf-2.1.3, sdl2-ttf-2.1.2, sdl2-ttf-2.1.1,
sdl2-ttf-2.1.0 (conflict: pkg-config package SDL2_ttf>=2.0.12, not found in
the pkg-config database)
[__1] rejecting: sdl2-ttf-2.0.2, sdl2-ttf-2.0.1, sdl2-ttf-2.0.0 (conflict:
pkg-config package SDL2_ttf>=2.0.0, not found in the pkg-config database)
[__1] rejecting: sdl2-ttf-1.0.0 (conflict: aztecs-sdl-text => sdl2-ttf>=2)
[__1] skipping: sdl2-ttf-0.2.2, sdl2-ttf-0.2.1, sdl2-ttf-0.2.0 (has the same
characteristics that caused the previous version to fail: excluded by
constraint '>=2' from 'aztecs-sdl-text')
[__1] fail (backjumping, conflict set: aztecs-sdl-text, sdl2-ttf)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: sdl2-ttf, aztecs-sdl-text
