artoolkit (CVS). =


Every time I try to run an ARToolkit/GLUT based program I get this messag=

I'm using the latest version of ARToolKit on Mac OSX 10.3.8. 

When i try to run mk_patt, calib_camera, simpleTest, etc. i get this message:
GLUT Warning: glutInit being called a second time.

...And the program hangs just before opening the main window and after asking
for camera settings.

However the programs simpleLite and simpleVRML works very well. 

I tryied 2 older versions of ART on the same machine a few months ago and
simpleTest2, simplVRML ran just fine.

I belive this could be a bug, but maybe im doing something very stupid. Can
somebody point me in the right direction?

Thanks in advance.

Pedro et al.,

Its a bug in the toolkit, not an error on your part.

Its caused by the non-conformant way that the ARgsub library calls 
glut. (This was part of the reason why ARgsub_lite was written, to 
avoid non-conformant use of glut.) It looks as if some change, either 
in glut on OS X 10.3.8 or perhaps in the ARTK video library means that 
a new work-around is required in order to keep programs that use ARgsub 
(e.g. simpleTest) working on OS X.

I am working on this. It may be a few days until I have a fix tested 
and packaged. In the meantime, suggest you base your code around 
gsub_lite rather than gsub (see simpleLite, twoView, or simpleVRML for 
example usage.)

Hi all,

A fix for this bug is now in CVS.

Simple instructions on how to configure a CVS client to get the latest 
ARToolKit source from CVS are at 
http://sourceforge.net/cvs/?group_id=116280 .

I will package a release once I have tested for side effects on Windows 
and Linux.

Regards,
Phil.
