Your probably want to go...

sudo aptitude install liballegro4.2-dev

that only installs the stuff you need to develop programs, it doesn't have the debugging library. Or you could just install it from source.

Assuming it's installed properly (and aptitude should take care of all that for you) you just need to #include <allegro.h> in your programs and link with -lalleg and it'll work fine.

Not quite. On linux you need to use `allegro-config --libs` instead of -lalleg

Adding `allegro-config --cflags` or `allegro-config --cppflags` to the compiler flags wouldn't hurt either.

Well that really does depend on the IDE (if any) that you are using, but in Code::Blocks...

{"name":"598110","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/6\/c\/6c297a816a203d05c5bcdb8444ac5c5b.png","w":664,"h":504,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/6\/c\/6c297a816a203d05c5bcdb8444ac5c5b"}
{"name":"598111","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/6\/0\/60af806d00cbd5d33af28028d34f112e.png","w":664,"h":504,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/6\/0\/60af806d00cbd5d33af28028d34f112e"}

If you are using a C project it should be `allegro-config --cflags` on the Compiler settings->Other options tab.

on the console do:

gcc game.c -o game `allegro-config --shared` or
gcc game.c -o game `allegro-config --static`

for a C++ project replace gcc with g++

that's all.

The `allegro-config --cppflags` is probably only needed when you have installed allegro to a non standard place. If you don't have root access to the machine or for whatever other reason.

I have done what you have said,and
I write a program like:-
#include<allegro.h>
int main()
{

allegro_init();
install_keyboard();
set_color_depth(16);
set_gfx_mode(GFX_AUTODETECT,640,480,0,0);

readkey();

return 0;

}
END_OF_MAIN();

and following error occured :-

-------------- Build: Debug in aaa ---------------

Compiling: main.cpp
g++: no input files
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings

please help me.

~~Did you create a new project? or just create a new source file and try to compile it? I will check that and see what happens... Well in my very old 8.02, not having a project compiled fine.~~

I will attach a project that is all setup to see if that works. (Attached is a simple hello world project. )

Also, if you use the <code>put code here</code> tags, your code will be nicely formated and easy to read.

I think,my error is due to wrong choose of the applicaton type,i.e.,while clicking on creat a new project i have choosen console application,probably it is wrong.Which one is correct.

I have always used "Console application" under linux, which is what the attached project was.

Same souce code if i paste on the project u have given,it runs.But in case of project i have created choosing console application doesn't works.It gives the errors like
/home/deepak/Desktop/123/main.cpp|9|undefined reference to `_install_allegro_version_check' at the line where allegro_init() lies.what is the problem i cant understand.

In a project go...

Project -> Build Options... -> <Project Name> -> Enable all compiler warnings (Overrides every other setting) [-Wall]

Where project name is top left, with release and/or Debug below it.

When you turn that option on go
Build->Rebuild workspace

The post the contents of build log here.

I hope that all made some sense (I am drunk, )
