plib-users

[Plib-users] joystick library

[McCracken R. <inf...@ya...>]

Hey, I'm trying to break free of the classroom
dependencies inflicted on me (college experiences).
So, here goes my first question (hopefully not too
naive - the subject matter in the archive is pretty
intimidating):

OK, running Windows '98 (try not to hate me too much
for doing this). I installed Cygwin and it seems to
work quite well. I downloaded the plib stuff (1.3.1).
I did what the readme told me to:

  ./configure
  make
  make install

OK, so now I have the example js_demo.cxx file in
/usr/local/plib_examples-1.3.1/src/js

In this directory there is also a file called
'js_demo.exe'. So I type './js_demo', and -Eureka!- it
works for both of my controllers.

But now I decide to try running some of my own stuff.
There is a problem at the point at which the statement
js[0]->notWorking () appears. This statement returns a
value of 1 (not working).

I attached the js_demo.cxx code for ease of viewing.

I figured I might try running js_demo.cxx on my own to
see if it was my code. So I type this:

g++ js_demo.cxx

The executable appears by default in a.exe. I run it
and the controllers still don't work. So if the code
that created js_demo.exe is js_demo.cxx, is there some
sort of option that I'm missing to get an executable
that works like the js_demo.exe? Or is the problem
more serious/complicated?

Any help would be GREATLY appreciated.

Thanks,
/R

I'm *trying*...but it's not going to be easy.

You have Cygwin - well, that's improved your
credibility *slightly*. :-)

Excellent.

Woohoo!

Not good.

Hmmm - I'm a little suprised that something as simple
as:

g++ js_demo.cxx

...would compile correctly - but since the JS stuff is just
a single header file - I suppose it could work.

However, the PLIB distro doesn't come with binaries or
executables of any kind - so js_demo.cxx *did* compile on
your setup...but with a different compile line.

I suggest you 'touch js_demo.cxx' - to change the date on it,
then re-run the 'make' for the top level 'examples' directory.

That should cause it to recompile js_demo.exe - and (importantly),
you'll see what commands it used to compile it.  I can't predict
what those will need to be because the 'configure' script generates
the Makefile's specifically to suit your machine's setup.

I'm guessing that there should be something like "-DCYGWIN=1" on the
compile command line.  Without that, it's probably compiling the set of
commands that would work under Linux rather than the ones for Windoze/Cygwin.
However, I havn't used Windoze for over 10 years...so my advice may
be worth nothing!

Perhaps someone on this list who uses CygWin will be able to offer
more help.

This should make a my_js_dem0.exe
c++ -o my_js_demo -DWIN32 js_demo.cxx -lwinmm -lplibul

I do not like having to define WIN32  to make this work

What do folks think of having the  make install  command
create a <plib/config.h> that contains the -Defines used when plib was
compiled
<plib/config.h> would then be include by our other headers

I thought the Windoze compilers did that automatically.

Sure - that's something that autoconf is able to do...I forget how
exactly...

AFAIK all Windows compilers define _WIN32 < notice underbar >

PLib using WIN32 is I believe a carryover from the FlightGear world.
When they started using it I do not know < before I arrived though >

We could go through the code and change all WIN32 to _WIN32
and see if that worked.  We of course would still have the occasional

#if defined(_WIN32) && !defined(__CYGWIN__)
where we really want Unix behaviour when using Cygwin

Any comments anyone on my just doing this ???

I think it is fairly easy todo but I have never done it.
Have we got amy autoconfig gurus on the list ?

Sounds good.

But I would guess that running make calls the compiler with include
path and other options set. You can only have defines and not compiler
options in the config.h. So, if I see things correctly, when someone
does a new project under Cygwin or Linux, he would still have to think
about doing autoconf stuff / a manual makefile or batch file
containing the correct settings for his system.=20

Well I just checked MSVC++ and it makes these preprocessor definations

WIN32,_DEBUG,_CONSOLE,_MBCS

Notice that the WIN32 has no underscore?  What a pain...

Guess the config.h file would have to have something like:

#if defined(_WIN32) && !defined(WIN32)
    #define WIN32
#endif

?

Sam could you please try this simple test program

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

#include <stdio.h>

int main( int argc, char **argv )
{
#ifdef _WIN32
	printf("_WIN32 found\n");
#endif
#ifdef WIN32 
	printf("WIN32 found\n");
#endif
#if !defined( _WIN32 ) && !defined( WIN32 )
	printf("Neither _WIN32 or WIN32 found\n");
#endif
	return 0;
}

Well that will teach me to post without checking first :)

_WIN32 found
WIN32 found

Opps.
