I am having trouble compiling the example #22 that comes with the allegro
library. I simply renamed the file cube.c and used djgpp to compile.
c:\>gpp cube.c
and i received this error:

cube.c: In function    'int main()':
cube.c: 455: no 'operator ++ (int)' declared for postfix '++', trying prefix
operator instead
cube.c: 455: no match for '++{anonymous enum} &'

so I went to line 455 which reads

455     render_mode++;

and I changed it to read:

455     ++render_mode;

and recompiled

c:\>gpp cube.c
and then I received this error:

cube.c: In function    'int main()':
cube.c: 455: no match for '++{anonymous enum} &'

any ideas what i can do to get rid of this last error?
I am new to graphics programming and If i can't get the sample to compile I
will never be able to learn to do this on my own?

Thanks for the help,
