How To Install Allegro Library In Dev C++

Allegro is a cross-platform library intended for use in computer games and other types of multimedia programming. When it comes to simple 2D game programming Allegro is great. It may be a little tricky to get allegro to install on some systems. They handle common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc. and generally abstracting away the underlying platform. However, Allegro is nota game engine: you are free to design and structure your program as you like.

Jun 27, 2006  Once you make the connection, select the latest version of Allegro and download it. Then click on tools again, the last option should be the one you want (install devpaks?). You will see the Allegro devpak in the list. Apr 12, 2019  Allegro 5 is a cross-platform library mainly aimed at video game and multimedia programming. It handles common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc. And generally abstracting away the. Installing and Using Dev C and Allegro Game Library. This page describes how to install both the Dev C Integrated Development Environment (IDE) and the Allegro Game Library. CISP 360 students will only need to follow the directions to install the Dev C IDE. CISP 499 students will need to install the Allegro Game Library as well.

Install it in any folder where you have write permissions (perhaps even a USB device). If you have administrator privileges, you can choose codeblocks-16.01mingw-setup.exe and install it in the same place your other standard software is installed. Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question.Provide details and share your research! Asking for help, clarification, or responding to other answers. Jul 22, 2005  have downloaded Dev-c, allegro library, mingw32 and dx70 for mingw. I configured allegro under mingw32 and installed Dev-c. I wrote a simple program looking like that: Allegro is not a part of the standard C language and thus not discussed in this newsgroup. You will need advice from the experts in a Dev-C or Allegro newgroup. If you want to use Allegro, you should be able to work comfortably with a computer and know the basics of programming in C or C either using an IDE or though the command line of your operating system.

According to the Oxford Companion to Music, Allegro is the Italian for «quick, lively, bright». It is also a recursive acronym which stands for «Allegro Low LEvel Game ROutines». Allegro was started by Shawn Hargreaves in the mid-90’s but has since received contributions from hundreds of people over the net.

To install run the command : open terminal and write-

# sudo apt-get install build-essential
Then we’ll install Allegro:
# sudo apt-get install liballegro4.2-dev
Thats it, allegro is installed and gcc is ready to compile allegro source.
To compile and run file by name inputfile.c in gcc type:
# gcc inputfile.c -o output `allegro-config --libs`
# ./output

For g++ compiler to run c++ program type-

# g++ inputfile.cpp -o output `allegro-config --libs`

# ./output

FINISH

EXAMPLE:-

For c-language program

#include <allegro.h>

int main(void)
{
/* you should always do this at the start of Allegro programs */
if (allegro_init() != 0)
return 1;

/* set up the keyboard handler */
install_keyboard();

/* set a graphics mode sized 320×200 */
if (set_gfx_mode(GFX_AUTODETECT, 320, 200, 0, 0) != 0) {
if (set_gfx_mode(GFX_SAFE, 320, 200, 0, 0) != 0) {
set_gfx_mode(GFX_TEXT, 0, 0, 0, 0);
allegro_message(“Unable to set any graphic moden%sn”, allegro_error);
return 1;
}
}

/* set the color palette */
set_palette(desktop_palette);

/* clear the screen to white */
clear_to_color(screen, makecol(255, 255, 255));

/* you don’t need to do this, but on some platforms (eg. Windows) things
* will be drawn more quickly if you always acquire the screen before
* trying to draw onto it.
*/
acquire_screen();

/* write some text to the screen with black letters and transparent background */
textout_centre_ex(screen, font, “Hello, world!”, SCREEN_W/2, SCREEN_H/2, makecol(0,0,0), -1);

/* you must always release bitmaps before calling any input functions */
release_screen();

/* wait for a keypress */
readkey();

return 0;
}

For C++ program

#include <allegro.h>

int main(){

allegro_init();
install_keyboard();
set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0);

putpixel( screen, 5, 5, makecol( 128, 200, 23));

circle( screen, 20, 20, 10, makecol( 255, 0, 0));
circlefill( screen, 50, 50, 25, makecol( 0,255, 0));

rect( screen, 70, 70, 90, 90, makecol( 0, 0, 255));

floodfill( screen, 140, 135, makecol( 255, 255, 0));

triangle( screen, 200, 200, 200, 220, 220, 210, makecol( 213, 79, 40));

release_screen();

FEATURES:-

How To Install Allegro Library In Dev C Windows 7

  • Cross-platform support for Windows, Unix, and MacOS X systems. (Formerly also DOS, BeOS and QNX – it may be possible to resurrect those platforms, with your help!)
  • Drawing functions including putpixel, getpixel, lines, rectangles, flat shaded, gouraud shaded, texture mapped, and z-buffered polygons, circles, floodfill, bezier splines, patterned fills, masked, run length encoded, and compiled sprites, blitting, bitmap scaling and rotation, translucency/lighting, and text output with proportional fonts. Supports clipping, and can draw directly to the screen or to memory bitmaps of any size.
  • Windows graphics drivers using DirectX in fullscreen and windowed modes, plus routines for drawing onto GDI device contexts.
  • Unix graphics drivers for X, DGA2, fbcon, SVGAlib, and standard VGA.
  • MacOS X native graphics drivers using CGDirectDisplay API for direct fullscreen gfx access and QuickDraw in a Cocoa window in windowed mode.
  • FLI/FLC animation player.
  • Plays background MIDI music and up to 64 simultaneous sound effects, and can record sample waveforms and MIDI input. Samples can be looped (forwards, backwards, or bidirectionally), and the volume, pan, pitch, etc, can be adjusted while they are playing. The MIDI player responds to note on, note off, main volume, pan, pitch bend, and program change messages, using the General MIDI patch set and drum mappings. DOS version currently supports Adlib, SB, SB Pro, SB16, AWE32, MPU-401, ESS AudioDrive, Ensoniq Soundscape, and Windows Sound System. Windows version supports WaveOut and DirectSound interfaces and the system MIDI drivers. Unix version supports OSS, ESD, and ALSA sound drivers. BeOS version supports BSoundPlayer and BMidiSynth interfaces. MacOS X native version supports CoreAudio, Carbon Sound Manager and QuickTime Note Allocator interfaces. All versions provide software wavetable MIDI playback.
  • Easy access to the mouse, keyboard, joystick, and high resolution timer interrupts, including a vertical retrace interrupt simulator in the DOS version.
  • Routines for reading and writing LZSS compressed files.
  • Multi-object data files and a grabber utility.
  • Math functions including fixed point arithmetic, lookup table trig, and 3d vector/matrix/quaternion manipulation.
  • GUI dialog manager and file selector.
  • Built-in support for 16-bit and UTF-8 format Unicode characters.
