Re: Looking for OpenGL "hello world"

[Chan Kar Heng <karheng at softhome dot net>]

if you've installed the *latest* cygwin & just used the default
settings & had not had previous versions of cygwin installed
nor do you have any instances of cygwin1.dll anywhere else
on your computer (due to other cygwin based s/w), then
getting it to compile a normal helloworld.c should be a piece
of cake (assuming you know enough basic *n*x stuff).

--- a.c ---
#include <stdio.h>
int main(void) {puts("Hello world!");return(0);}
/* the empty line below is required to compile properly */

-------------

should work just doing gcc -o a a.c.

get the X servers working under cygwin.
make sure you can run xclock or similar to test things out.

get mesa, take their examples (the X windows ones),
and try the simplest one out.
(you might want to break apart even that simple code to
test what works & what doesn't).

it might help to download source codes for xclock &
see what commands r used to compile X apps on cygwin too.

i'm sure you'll hit some walls along the way, but it's around
there.

I'd be better off ordering a new computer and installing Redhat myself I think, although finding an OpenGL "hello.c" program in their docs isn't a piece of cake either.
