* gcc C compiler (other compilers may work, but are not officially supported)
* GNU make (other similar "make" tools may work, but are not supported)
* SDL library v1.2
* SDL library v1.2.x, or v2.0.x
* SDL_image library
* libpng (not on MacOSX)
* FreeType library (optional, for truetype fonts)
* libpng
* tiff
* SDL_ttf library (optional, for truetype fonts)

* FreeType library (optional, for truetype fonts)
* Lua library v5.3, (v5.1 or v5.2 are also supported)
(optional, for Lua scripting)
Note: on some platforms it is possible to build without SDL :
using GDI API under Windows
using X11 under Linux/FreeBSD/etc.
see usage of API= variable below.
Extra requirements for Windows:
* a POSIX environment: MSYS is fine, maybe Cygwin would work as well.
* use Mingw C compiler instead of gcc
* MS Visual Studio project files are also provided in project/msvc/
but are not officially supported
Extra requirements for UNIX/X11 (Linux, FreeBSD, ...):
* pkg-config (optional, for Lua scripting)
* X11 headers (optional, for truetype fonts)
* pkg-config
* Xlib headers
On Debian-based distributions you should be able to get all these files by
simply running the following command from a terminal :
sudo aptitude install gcc make libsdl1.2-dev libsdl-image1.2-dev libsdl-ttf2.0-dev libfreetype6-dev liblua5.1-0-dev lua5.1
simply running the following commands from a terminal :
$ sudo apt-get install gcc make libfreetype6-dev liblua5.3-dev libtiff5-dev libpng-dev
$ sudo apt-get install libsdl1.2-dev libsdl-image1.2-dev libsdl-ttf2.0-dev
or if you want to use SDL 2.0.x :
$ sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev
On macOS, we suggest to use macports https://www.macports.org/ :
$ sudo port install lua libpng tiff
$ sudo port install libsdl libsdl_image libsdl_ttf
or
$ sudo port install libsdl2 libsdl2_image libsdl2_ttf
It is also possible to use the Makefile in 3rdparty/ directory to build
the required lib. This has been developped for win32 cross compilation
but may work for other platforms.

=== Build variants ===
By default GrafX2 is built for SDL 1.2.x. use API=x11 API=sdl2 or API=win32
to change that.
The default compilation is optimized ( -O ), with debugging symbols for GDB.
Compile with OPTIM=0 to disable optimizations, if you have some real debugging
to do.

== Windows ==
It is also possible to compile from linux, with this command :
$ make WIN32CROSS=1
$ make WIN32CROSS=1 [API=win32]
You will need the mingw cross-compiler, and all the librairies listed above.
Variables CROSS_CC, CROSS_PKGCONFIG and CROSS_SDLCONFIG can be set :
$ CROSS_CC=mingw32-gcc CROSS_PKGCONFIG=mingw32-pkg-config CROSS_SDLCONFIG=/path/to/ming32/sdl-config WIN32CROSS=1 NOTTF=1 make
You will probably first need to build dependencies by running
$ make WIN32CROSS=1
from the 3rdparty/ directory.
