Hi,

I'm test-driving pal and can't seem to get hello.lisp to run.  From the
command prompt, I get this:

In both cases, it creates the frame with a title and black background.  My
environment is a slackware linux box hosting sbcl and the libraries, but I'm
accessing it via a windows box using ssh (PuTTY) and my X-server is Xming.
I have no problem running other X apps in this environment.  BTW, the
graphics card identified by pal is the graphics card on my windows box,
which makes sense.

It looks like it can't find/create/use a default font.  Thoughts?

TIA,
Dave

Looks like I made a good old off-by-one error on ffi.lisp. Should be fixed  
in the cvs, or you could just change the font structure declaration in  
ffi.lisp to look like:

(defstruct font
   (file nil)
   (image nil :type (or boolean image))
   (glyphs nil :type (or boolean (simple-vector 256)))
   (height 0 :type u11))

For some reason the error doesn't always show up... Let me know if this  
helps you get any further.

I have used pal before with similar setup, so it _should_ work. But for  
some reason I'm not able to get work right now that I tried it :( Probably  
just something wrong with my xming settings, I hope.
And remember that the performance might not be too good, maybe enough for  
dev-work though. Let me know if you get it working :)

I made this change.  Maybe I should be looking at the CVS since I'm still
having problems.

I still am seeing a frame with the correct title, a black background, but
no text.  I also tried the example from the manual pp. 7.  In order to get
that example to work, I had to do (use-package :pal) (It might be because
I'm using an old ASDF).  That got the example to compile, but again, no
text.  I also looked up the params to clear-screen and changed the color
to (127 127 127) and (255 255 255), but I still only saw a black
background with no text.  Hitting Enter makes the window disappear, so
(wait-for-keypress) is working :-)  According to my handy-dandy html color
chart, I was expecting a yellow background initially, then in my tests a

Any additional thoughts would be appreciated.  I'm using the latest SDL,
but whatever my slackware install has for OpenGL, which looks like

OpenGL version string: 1.2 (1.5.3)

(per glxinfo).  The OpenGL website talks about version 2.1, but I haven't
come across a downloads link.  Looks like its heavily integrated into X.

Any additional thoughts?

Looks like event handling is working fine but for some reason window  
update is not working. Just to be sure try to upgrade to the cvs head  
version. (Note: Colors are handled a bit differently in the latest  
version; instead of (clear-screen 255 255 255) you should use  
(clear-screen (color 255 255 255)). But some functions still take separate  
rgba values, it is a bit messy atm...)

I'll see if I can get it working on my own xming setup.

That should work just fine.

I've upgraded to cvs head, but no change in the results.  I don't have a
monitor on the linux box, so I can't really try it locally.  Is there a
function call result I could look at?

Thanks,
Dave

Well, there are a few things you could try from the repl (in pal package),  
just to see how much works.

(open-pal :paths "/path/to/my/images/") ;; opens pal window with default  
settings

(clear-screen +white+)

(update-screen) ;; update display, should signal in case of opengl error

(wait-keypress) ;; to see if event handling works

(draw-image (load-image "some.png") (v 0 0)) ;; loads and draws an image  
 from "path/to/my/images"

(screen-to-array (v 0 0) 100 100)
;; this should return part of the window as an array of rgba values. E.g.  
after (clear-screen +white+) it should return all 255s. I'm not sure if it  
really should work in this situation but might as well try.

Other than that it is really hard to say where the problem might be. I  
just tried some of the more demanding X11 apps remotely with xming/win32  
and xorg/linux and the result were quite random, from total hang to  
problems with screen update so it might be a general problem with SDL  
apps. With my setup PAL hangs completely at open-pal :(

Assuming you are on Windows PAL should work natively there. But then of  
course the environment isn't as nice...

now that's interesting: the frame really is black (assuming the first

I really don't want to develop in Windows (I'm trying to break the
addiction :-), but I'll probably look into it.  I'm also trying to get
garnet to compile.  That's fun.


Thanks,

Subject: [Pal-devel] title window hanging
Message-ID: <77ca20d90801151503p190714c2wcc3e9f865e839ea5@mail.gmail.com>

Hey everybody,

This is my post here and I am not even sure is I am posting it right.  I am
having a similar issue as described by someone not long ago, when trying to
run examples from pal/examples:  the window with a title pops up and hangs,
it doesn't show anything, doesn't respond to events, Windows sais that the
application is not responding.  Meanwhile the listener sais
"FFI:FOREIGN-CALL-OUT: 0 cannot be converted to the foreign type
SINGLE-FLOAT".
I also have to use (in-package: pal) before I can run any examples.

I use windows XP, AMDX2 64bit, nVidia GTX7800, Clisp-2.43.  I can use
Linux to and probably using a Linux PAL setup or SBCL
would solve the issues, dunno.

Maybe that's too much to ask - but is it possible to write some checking
program that would check if everything, required by PAL, is installed and
works fine?  I am really new to Lisp and it would be fantastic to use PAL.

Thanks for the great work!
Regards,
Vlad

Luckily this isn't too hard to fix, but should probably be mentioned in  
the manual since it had me puzzled a bit when testing pal on CLisp.
For some reason CLisp runs by default in non-ANSI compatible mode which  
causes problems like that one mentioned above. To fix it either:

1) Set custom:*ansi* to T after starting CLisp
2) Put (setf custom:*ansi* t) in your .clisprc file
3) Start CLisp with the -a command line argument

That _should_ fix, let me know if still doesn't work.

PAL should work fine on Windows, with either or SBCL or CLisp. Allegro and  
Lispworks are less tested but in theory there shouldn't be problems.

After loading PAL try (load "<pal-dir>/examples/teddy.lisp") and  
(pal-example::example) from REPL. If that works it is very likely that  
everything is working correctly. You could also try the "polygons.lisp"  
example, it should start automatically after loading.
If you have more problems let me know :)
