SAC SDL Module

About

This is a SaC module that wraps around the SDL (version 1) library and can be used for visualisation or graphical interfaces.

Build Instructions

You'll need to have installed sac2c and have a copy of the Stdlib installed as well. You'll also need to have SDL version 1 C-library and most likely operational pthreads. NB. The SDL version 2 library is not, at present, supported.

$ cd SDL
$ git submodule init
$ git submodule update
$ mkdir build
$ cd build
$ cmake ..
$ make -j4
$ make install //you might need to use `sudo'

Variables that can be passed to CMake

When running CMake it is possible to pass the following variables:

• -DTARGETS=x;y;z --- build stdlib for targets x, y and z. (defaults are seq; mt_pth)
• -DSAC2C_EXEC=/path/to/sac2c --- specify sac2c executable directly. Otherwise CMake will try to find sac2c on yout PATH.
• -DLINKSETSIZE=n --- set -linksetsize n when calling sac2c. This option is responsible for the number of C functions that are put in a single C file when compiling a SaC program. The rule of thumb:

  • value 0 is the fastest time-wise but potentially results in a large memory consumption

  • value 1 reduces the memory consumption to minimum, buy significantly increases compilation time.

    Default value: 500.
