[gtkada] Problems running testgtk.

[Jeffrey D. Cherry]

Hello,

I just installed GtkAda from the GNAT GPL 2006 package.  The installation 
reported no problems.  I tried running the testgtk.exe file from a command 
shell with the current directory "d:\GtkAda\share\examples\gtkada\testgtk" and 
it gave me the following error: 

"The procedure entry point gdk_pixbuf_save_utf8 could not be located in the 
dynamic link library libgdk_pixbuf-2.0-0.dll."

Thinking there is a conflict between two or more "dll" files of the same name, 
I moved to the "d:\GtkAda\bin" directory and tried running testgtk.exe again 
using a fully qualified path.  The application started successfully.  However, 
it did have problems running several of the tests - presumably because it is 
designed to be run from its original directory.  For example, on the "Gtk demo" 
tab, after expanding the "Containers" tree, if I select "handle box", the 
progream aborts with "raised PROGRAM_ERROR : EXCEPTION_ACCESS_VIOLATION".

Checking "d:\gnat\gpl_2006\bin" and "d:\gtkada\bin" for ".dll" files, sure 
enough, there are several ".dll" files of the same name but have different 
sizes, which I assume is the source of the error.  I checked the path and found 
"d:\gnat\gpl_2006\bin" before the "d:\gtkada\bin" directory.  When I put 
"d:\gtkada\bin" at the beginning of the path, then running testgtk.exe from its 
own directory, I got one error.  The error I got was under the "Gtk demo" tab, 
under the "Composite Widgets" branch, selecting the "plot" item, I got the 
error "GLib-ERROR**: gmem.c:172:failed to allocate 624 bytes aborting...".  
After the application aborted, I got the following at the command shell "This 
application has requested the Runtime to terminate it in an unusual way.  
Please contact the application's support team for more information."  The only 
other failure was on the "OpenGL demo" tab which gave the message that "OpenGL 
has not been installed on this system.", which I can't really call an error.

I'd like to use GtkAda on a couple of projects, but these errors concern me.  
Is there a way to identify a particular ".dll" file in a particular directory 
in order for the application to not depend on the system path?  Perhaps a 
linker option pragma?  Is the cause of the access violation error due to a 
problem with Gtk or the testgtk application?  Is the GLib error due to a 
problem in GLib, or is it because of a problem running under my operating 
system?
