Re: Agar 1.4 doesn't compile / Agar trunk doesn't run

Stephen M. Webb — 2013-02-08T02:12:54


The problem is the configure file hardcodes -Wall -Werror into CFLAGS when
running autodetection tests, which is exactly the wrong thing to do.  As a
result, autodetection of native 64-bit support fails (even though the
compiler supports it), and the fallback code is invalid.

The following snippet works on Debian and Ubuntu when run in the top-level
source directory.

sed -i -e 's,-Werror,,' ./configure
../configure --prefix=/usr

Agar Digest, Vol 44, Issue 1

2013-01-22T08:22:48

Hi all, 

Can you please tell how does Agar integrates OpenGl?  AGAR already exists in the UEFI environment. I want to port OpenGL such that it is integrated as a part of Agar. 


Thanks 
Ritvik

Re: AG_Textbox is not taking any input

JC You are brilliant! 
Just add `SDL_EnableUNICODE(SDL_ENABLE);' before agar's initialization, and 
everything is working perfectly well.
It corrects the SDL's event interpretation, and nothing have to be corrected in 
the event loop.

Re: AG_Textbox is not taking any input

JC — 2013-01-16T19:25:28

Hi and thanks, this solution works for me too, I had the same problem.

 
But then I get QWERTY minus caracters in the Agar GUI (I have an AZERTY keyboard). The solution I found is :
    * To put "SDL_EnableUNICODE(SDL_ENABLE);" somewhere in the SDL initialization
    * To not use "dev.data.key.ucs= (int)dev.data.key.ks;" but "ag_event.data.key.ucs = (int)sdlEvent->key.keysym.unicode;" in my custom event loop


It seem's it works fine now :)

      dev.data.key.ucs= (int)dev.data.key.ks;
      break;
....
  AG_ProcessEvent(NULL, &dev);
....
  Where `dev' is retrieved from the agar event quene.` dev.data.key.ucs= 
(int)dev.data.key.ks;' replace the misinterpreted Unicode character with the 
correctly interpreted ks.

Re: Need help to compile Ada-bindings on FreeBSD

Gustav Johansson — 2013-01-08T09:43:50

Hi,

managed to get past the error. I found the c_string dependency on io7m.com and 
after installing it I got further. I can now (after some modifications to the 
build system) compile and install the "ada-core" part.

I now get stuck at the "ada-gui" part because of a misssing file: agar-core-
types.ads. This file does not exist in the libagar source, but searching 
through the older releases I found it in version 1.3.4. Later versions do not 
have it. Is there a reason for this? Or has it simple fallen out by mistake?

I am sincerely interested in getting the Ada-bindings to work but I have no 
experience in the type of build system used in the bindings. Anybody care to 
point me in the right direction?

Regards,
Gustav

Need help to compile Ada-bindings on FreeBSD

Gustav Johansson — 2013-01-07T07:10:29

Hi,

I'm trying to install libagar with Ada-bindings on a FreeBSD-9.1
machine. The library itself compiles and installs according to
instructions without a hitch. The Ada-bindings are a different matter
though.

As far as I can gather from the README files, I should download and
install AdaSDL first, which I have done. The next step seems to be to
run "make" in the ada-core folder, and this is where I get stuck...

AGAR support for OpenGL in UEFI

Hi All,

Can you please tell does AGAR library support OpenGL implementation in UEFI environment? If not is it feasible to achieve the same?

Re: textbox scrollbars

Ben Collver — 2012-12-02T15:01:18

Hello,

The problem exists between the chair and the keyboard.  Instead of 
putting the text in the widget label, I should bind the textbox to a 
copy of the string.

Sorry for the noise,

Good day,

Attached is an example program that shows its own source code in a 
textbox.  Also attached is a screenshot of the program output.  I am 
using Agar SVN on Linux with SDL.  I expected a vertical scrollbar, but 
there is none.  The horizontal scrollbar is visible.  I expected the 
text to scroll horizontally, but it remains fixed when I move the 
horizontal scrollbar.  Do you know of a working example that uses the 
scrollbars in a textbox widget?

Thank you,

Thanks, but I tried exactly that and the results were the same.
I'm using lubuntu 12.4 by the way.
unresolved symbol: jpeg_resync_to_restart seems to indicate that agar libraries 
should have been linked to libjpeg, but weren't for some reason. I have libjpeg 
installed, including its dev package.

Essentially, what you suggested and what I did at first were identical except 
that you had libsdl-image1.2-dev installed, and I did not.


So, basically, the problem still is not solved....

Hi, here's what I did to get agar working on Debian GNU/Linux:

sudo apt-get install autoconf libsdl1.2-dev libsdl-ttf2.0-dev
libsdl-image1.2-dev
svn checkout http://dev.hypertriton.com/agar/trunk agar-trunk
cd agar-trunk

Hope this helps you,

Agar 1.4 doesn't compile / Agar trunk doesn't run

Philip — 2012-11-29T04:48:51

I stumbled upon Agar yesterday, and from the description and screenshots I think 
it is exactly what I have been looking for. However, so far I have been unable 
to do anything with it.
Agar 1.4.1 won't build (linux x86_64/gcc 4.6.3), make depend runs fine, but make 
all fails with the following errors:

Re: Agar 1.4.1 on Debian Squeeze VM

Sean Ulrich — 2012-11-11T17:43:46

That did it, thanks Josh!  So, running those commands from my 1.4.1
tarball directory gave the same results (Seg Fault), but checking out
the latest trunk and doing the same steps succeeded.  There must be
some fix in the latest code that is needed for Debian to work
properly.  So hello world is working now, although I do get an error
from OpenGL:

OpenGL Warning: Failed to connect to host. Make sure 3D acceleration
is enabled for this VM.

I don't have 3D acceleration enabled in the VM so this makes sense.
But, will this cause any issues going forward?  If I can run without
OpenGL at all, that would be preferable.  My eventual goal is to make
a light weight build and port it to a 100Mhz 32-bit micro (similar to
an ARM Cortex M0).  Is there a way to manually disable OpenGL support?

Thanks,

Sean

Agar 1.4.1 on Debian Squeeze VM

Sean Ulrich — 2012-11-11T15:35:35

I appreciate all your work putting this together.  It looks very impressive.

Like the previous post from Josh Branning 
(http://thread.gmane.org/gmane.comp.lib.agar.general/675), I am attempting to 
install Agar 1.4.1 on Debian Squeeze and am having trouble.  But, unlike Josh, I 
have the added variable of running Debian in a VirtualBox VM.  Here is what I've 
done:

I downloaded the 1.4.1 tarball and unzipped to ~/agar-1.4.1
install", and "sudo ldconfig".  Everything seems to install correctly.  I then 
made the hello.c from the website and it compiled successfully with "gcc -o 
hello `agar-config --cflags` -g hello.c `agar-config --libs`"

However, when I run "./hello" I get Segmentation Fault.  Checking gdb shows:

Program received signal SIGSEGV, Segmentation fault.

Re: Closing a window from a function.

Julien Nadeau — 2012-11-07T02:03:00

Hi Josh,

Admittedly this isn't obvious from the documentation, but windows
should be destroyed this way:

AG_ObjectDetach(win);

Detached windows are automatically freed by the event loop, so calls
such as AG_ObjectDestroy() or free() must not be used. To pass a
pointer to the window to your event handler routine:

 AG_ButtonNewFn(win, 0,
     "Button Function", Button_Function, "%p", win);

static void
Button_Function(AG_Event *event)
{
 AG_Window *win = AG_PTR(1);
 
 AG_ObjectDetach(win);
 }
