Dependencies
============

	GLEW, GLM, SDL2, SDL2_image, SDL2_net, SDL2_ttf, OpenAL, freealut, zlib

	CppUnit for tests
	Cppcheck for linting

archlinux: pacman -S \
	glew glm sdl2 sdl2_image sdl2_net sdl2_ttf openal freealut zlib \
	cppunit cppcheck

debian: apt install \
	libglew-dev libglm-dev libsdl2-dev libsdl2-image-dev libsdl2-net-dev \
	libsdl2-ttf-dev libopenal-dev libalut-dev zlib1g-dev \
	libcppunit-dev cppcheck

	(!) you may have to build the tests with CPPFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0

centos: yum install \
	glew-devel glm-devel SDL2-devel SDL2_image-devel SDL2_net-devel \
	SDL2_ttf-devel openal-soft-devel freealut-devel zlib-devel \
	cppunit-devel cppcheck

	(!) you need the "epel" repository for SDL2 et al. `yum install epel-release`

Makefile
========

Targets
-------

all:
	build everything

release (default), debug, profile:
	build executables tuned for running, debugging, and profiling

run:
	build and execute the main binary with state path set to ./saves

server:
	same as run, only in server mode

server:
	same as run, only in client mode and the save path is set to
	./client-saved to prevent clashes with a running `make server`

test:
	build and run tests

unittest:
	build and run tests that require no X server

gdb, cachegrind, callgrind:
	build the binary suited for given tool and launch

clean:
	remove intermediates

distclean:
	remove intermediates and artifacts
	(also those generated by tool invocations!)


Variables
---------

CXX, LXX:
	compiler/linker used for C++ sources/objects

LIBS:
	names of libraries (for pkg-config)

CPPFLAGS, CXXFLAGS, LDXXFLAGS:
	flags for the preprocessor, compiler, and linker

DEBUG_FLAGS, PROFILE_FLAGS, RELEASE_FLAGS:
	flags for building binaries in debug, profile, and release mode
