If you need to, download Scons from http://scons.org/pages/download.html
This builder automatically downloads SDL2 on Windows and Mac as needed.
On Linux you must install SDL2 'the Unix way' or by installing the libsdl2-dev
package before running this script.
On Windows you will need an installation of Microsoft Visual Studio or MinGW.
To test this SCons script you can use the `build` alias, which will build
libtcod and all samples without touching any files outside of this
subdirectory:
```
scons build
```
SCons can compile faster using multiple cores, use the`-j <threads>` flag.
To build and install libtcod and all sample programs into the root libtcod
folder, use the `develop` alias. The default mode is `MODE=DEBUG`, so you'll
also need to change `MODE` if you want a release build:
```
scons develop MODE=RELEASE
```
If you only need to work with the libtcod shared library you can use
`develop_libtcod` instead.
The compiled binaries will be 32-bit by default.
You can compile 64-bit binaries with the `ARCH=x86_64` variable:
```
scons develop MODE=RELEASE ARCH=x86_64
```
On Mac this script will always make a universal build, ignoring `ARCH`.
Windows has the option of using the MSVC compiler (default) or MinGW compiler.
To use MinGW set the `TOOLSET=mingw` variable.
A packaged release can be made with the `dist` alias.
Additional variables can be changed such as the compiler and linker flags. The
easiest way to change these options is by editing `config.py`.
To see an additional list of extra variables you should run `scons -h`.
