Pàgina nova

=Referències i tutorial=

Tutorial:
*[[Imatge:Curso de Programacion videojuegos C++ Allegro3.pdf]]
=Instal.lació synaptic (v4.2)=
instal.lo liballegro4.2, liballegro4.2-dev, els exemples, i liballegro4.2-plugin-jack (JACK audio plugin)

els exemples del paquet allegro-examples estan a /usr/bin/allegro-examples

==Integració amb JACK (TBD)==
Mirant el synaptic he vist el paquet:
liballegro4.2-plugin-jack: JACK audio plugin for the Allegro library

=Instal.lació SVN (v4.9)=
<pre>
$ mkdir /usr/share/allegro
$ cd /usr/share/allegro
$ svn co https://alleg.svn.sourceforge.net/svnroot/alleg/allegro/branches/4.9
</pre>
README_make.txt discusses compilation with GNU make. This applies to Unix-like operating systems such as Linux, MacOS X and MinGW on Windows.
<pre>
Linux users likely have all the dependencies already, except PhysicsFS
and DUMB. If your distribution uses separate development packages, they
will need to be installed. The packages are probably named *-dev or *-devel.

These are the dependencies required for the addons:

- libpng and zlib, for PNG image support (Unix and older MinGW only)
Home page: <http://www.libpng.org/pub/png/>
Windows binaries: <http://gnuwin32.sourceforge.net/packages/libpng.htm>

- libjpeg, for JPEG image support (Unix and older MinGW only)
Home page: <http://www.ijg.org/>
Windows binaries: <http://gnuwin32.sourceforge.net/packages/jpeg.htm>

- FreeType, for TrueType font support.
Home page: <http://freetype.sourceforge.net/>
Window binaries: <http://gnuwin32.sourceforge.net/packages/freetype.htm>

- Ogg Vorbis, a free lossy audio format. (libogg, libvorbis, libvorbisfile)
Home page: <http://www.vorbis.com/>

- FLAC, a free lossless audio codec. (libFLAC, libogg)
Home page: <http://flac.sourceforge.net/>

- DUMB, an IT, XM, S3M and MOD player library. (libdumb)
Home page: <http://dumb.sourceforge.net/>

- OpenAL, a 3D audio API.
The audio addon can use OpenAL, although the 3D capabilities aren't used.

Anem a instal.lar-ho:
<pre>
$ cd /usr/share/allegro (és on he descomprimit l'Allegro)
$ sudo mkdir Build (és on s'instal.larà)
$ cd Build
$ sudo cmake ..

</pre>

es genera el Build, i es veu les llibreries que tinc i les que no tinc. S'ha generat el Makefile:
<pre>
$ sudo make
$ sudo make install
</pre>
S'instal.la bé i ja puc veure algunes demos
<pre>
$ /usr/share/allegro/Build/demos/speed
$ ./speed
</pre>
i els exemples de codi (els binaris) i els codis font corresponents estan a:
<pre>
$ cd /usr/share/allegro/Build/example (binaris)
$ cd /usr/share/allegro/examples (codis font)
</pre>

Ja puc compilar el projecte més senzill:

'''main.cpp''':
<pre>
#include <allegro.h>

int main()

{

allegro_init();
install_keyboard();
set_gfx_mode(GFX_AUTODETECT_WINDOWED, 320, 200, 0, 0);
textout_centre_ex(screen, font, "Hello, World!", 160, 100, makecol(255, 255, 255), -1);
readkey();
return 0;

}
</pre>
<pre>
g++ main.cpp -o main `allegro-config --static`

The program 'allegro-config' is currently not installed. You can install it by typing:
$ sudo apt-get install liballegro4.2-dev
</pre>
però clar, de fet t'instal.la allegro4.2 quan de fet jo tinc instal.lat ara la versió 4.9
<pre>
g++ main.cpp -o main `allegro-config --static`
</pre>
i ara ja compila i s'executa el codi més simple.

Les llibreries estan a '''/usr/local/include/allegro5/'''. Per exemple, anem a compilar l'exemple ex_blit.c

No compila, però no és un problema de què no trobi la ruta /usr/local/include/allegro5/
