Problem with gtk

2006-12-16 Thread Naveen Kumar 
Hi all,

I am using an hand held device running on montavista linux,
1) i wrote a c program 

 int main ()
   {
 int i;
 while (i  25000)
 printf (%d\n, i);
   }
it works very fine in my machine without any problem. (it takes around 1.2
minutes)

2)If try to run the same part of code on a button click using gtk,
the application is crashing around 30 seconds saying just Terminated.

Is there any time out as such we can specify for gtk applications..

Please help me regarding this.
  
Thanks and Regards
Naveen

Re: GTK-GUI and video display

 Hi,
 
 I need to run a GTK GUI and display video via DFB. I understand that the
 GTK-GUI would be using layer 0 (primary) and video would use
 Layer 1. However when the GUI comes up then the GUI/video layer is not
 visible. Any inputs on whether any changes are required to GTK-DFB 
 to be able to display GUI and video simultaneously?

uhm.. are you trying to have two different processes rendering on the 
same VT ? in this case i guess you'll have to build dfb with multicore 
option toghether with the fusion module too.
I'm cc'ing directfb-users as this seems more a dfb than gtkdfb issue.

would really appreciate anything you may remember on how you got this
solved. Thanks

So is Pango crosscompiled and installed or not?  Seems it
isn't, at least it isn't mentioned...

  But when i config the gtk2.6.10, the error is:
  .
  *** Can't link to Pango. Pango is required to build
 ^^
  *** GTK+. For more information see http://www.pango.org.


...and it isn't found.

Do you expect any other advice than to (cross)install Pango?
Am I missing the point?

Makefile.am Help for GnomeProgram make errors

2006-12-16 Thread Tony Freeman 
Hello,

I am using Anjuta.  I need help with a particular piece of configuration
in order to make GnomeProgram work properly.

I get this series of errors when trying to make the program:

main.c: In function ‘main’:
main.c:121: error: ‘PREFIX’ undeclared (first use in this function)
main.c:121: error: (Each undeclared identifier is reported only once
main.c:121: error: for each function it appears in.)
main.c:121: error: ‘SYSCONFDIR’ undeclared (first use in this function)
main.c:121: error: ‘DATADIR’ undeclared (first use in this function)
main.c:121: error: ‘LIBDIR’ undeclared (first use in this function)

I know I need to put PREFIX, SYSCONFDIR, etc in the Makefiles as a
CFLAGS -DPREFIX= thing, but I'm not sure how do do this properly.  

I *think* I need to add something to Makefile.am ... but I'm not sure of
the magic entry to put there.

Please help!

RE: Problem with gtk

2006-12-16 Thread Viraj Chatterjee 
If the intention is to run a loop for 25000 iterations, then this is a
horrible way to attempt that.

You haven't initialized i, neither are you incrementing it.

i is uninitialized here. It contains a random value...

  while (i  25000)
  printf (%d\n, i);

...which doesn't change at all while the loop is running.

}
 it works very fine in my machine without any problem. (it takes around 1.2

So I don't understand why this program terminates at all (it should
terminate either *immediately* or *never at all*.

 2)If try to run the same part of code on a button click using gtk,
 the application is crashing around 30 seconds saying just Terminated.

Even 30 seconds seem too long (or too short, depending on the initial
value of i).

BTW, if you compile that with -Wall, the compiler would have told you
that (needs option -O as well):

 | [EMAIL PROTECTED]:~$ cat fo.c
 | #include stdio.h
 | 
 | int main ()
 | {
 |   int i;
 |   while (i  25000)

 | }
 | [EMAIL PROTECTED]:~$ gcc -O -Wall -o fo fo.c
