gtk_init_check() call fails and return -1
 
I am doing

if(!gtk_init_check(NULL,NULL)
fprintf("gtk not initialised properly");

Can you pls help me why the call is failing on SLES 10 ia64?

I have installed

gtk
gtk2
gtk-devel
gtk2-devel

What's the reason it is failing?
Can we somehow know what's the reason behind it ?

Thnx in advance

hi,
Code:
if(!gtk_init_check(NULL,NULL))
      printf("gtk not initialised properly");
..."!" means in your case zero(succes)

this should be better;)
Code:
if(gtk_init_check(NULL,NULL))
      printf("gtk not initialised properly");
"!" means false, and false is only 0.
1, 2, 3 ....-1, -2 means true.

if you see the return value of gtk_init_check() when it fails to initialise properly...its false...

so my code is correct only...

any help why gtk_init_check(NULL,NULL) is failing?
Am I passing the wrong arguments??

Maybe try replace temporarly if(!gtk_init_check(NULL,NULL))
with if(!gtk_init(NULL,NULL))

gtk_init() is verbose I believe, so you may have a chance to see where it does not work
