How to compile this C version.
------------------------------

Here are the instructions to compile the test programs with gcc :

A. Display component selection :
--------------------------------

choose one of the following display  components,  according  to  your
system ( or create you own ) :

  - disp_bcc.c      Borland C 3.1 ( DOS  16 bits   )
  - disp_emx.c      Gcc + Emx     ( OS/2 32 bits   )
  - disp_x11.c      Gcc + X11     ( any X11 system )

and copy it to

  - 'ttdisp.c'

like with :

  copy disp_emx.c ttdisp.c


B. Component Compilation :
--------------------------

All files in 'tt*.c' as well as 'raster.c'.

Example :

gcc -Wall -O3 -c tt*.c raster.c

      ^    ^   ^
      |    |   |___ compile only
      |    |
      |    full optis ( optionnal )
      |
       full warnings


C. Test programs :
------------------

Link  them  with  standard  ANSI  libs  and  the previously compiled
components ( don't forget math and X11 libs ).

Examples :

gcc -Wall -O3 zoom.c raster.o tt*.o
gcc -Wall -O3 testtime.c raster.o tt*.o

Here  you  are,  you  can  now  start  'zoom'  and  'testtime'  in a
full-screen session ( for non-Linux systems ).

D. MAKEFILE :
-------------

We provide you with a mini makefile called 'makefile.gcc'. It is
configured to compile an X11 version on Linux.
