kdevelop + allegro http://www.allegro.cc/forums/view/588758 Allegro.cc Forum Thread matthew@allegro.cc (Matthew Leverton) Tue, 28 Nov 2006 18:23:54 +0000

Hi,

I have been reading the site and the forums, but I still dont know how to compile allegro within kdevelop.

I have installed allegro, and example's from tutorials compile just fine (outside kdevelop with "$make".

Can someone write in short how to set kdevelop up? Or a link to a tutorial?

It used to work around a year ago, I'm not sure if it still does. IIRC iIt is based on the awiki article so it might not.

Can you post your src/Makefile.am, Makefile.am, and configure.in, please?

Project name: allegro2

Makefile.am:

They had to be the other way around, now it seems to compile just fine ;D

Thanks for that tread you gave me, because there was someone with the same problem.

Please remove these lines:

AM_PATH_ALLEGRO([MINIMUM-VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
AM_PATH_ALLEGRO()

They were just an example :)

At your option, you can leave AM_PATH_ALLEGRO() and instead remove AM_PATH_ALLEGRO(4.1.0).

Haha, I found it weird anyway::)

Now I have changed the code, but it doest compile, make doesnt do anything anymore, just:
make[2]: Nothing to be done for `all'.

my bad, made a few stupid mistakes, it works:P

]]> no-reply@allegro.cc (BackwardsDown) Mon, 27 Nov 2006 22:47:10 +0000

That means it's already done. It only rebuilds it if you have changed the files :)

]]> no-reply@allegro.cc (CGamesPlay) Mon, 27 Nov 2006 23:24:38 +0000

Yes, I was changing the wrong files:-/

Now it compiles fine, but when I run my program from the command line, it fails at this line:

Quote:

blit(my_pic, screen, 0,0,0,0,480,360); //Draw the whole bitmap to the screen at (0,0)

Quote:

niels@niels-desktop:~/Programmeer/C++/allegro2$ ./src/allegro2
Shutting down Allegro due to signal #11
Segmentation fault

I load my blit like this:

Quote:

my_pic = load_bitmap("picture.bmp", NULL); // Load our picture

The strange thing is, that when I run my program in kdevelop with build->execute program or debug->start the program just works!

Problem is the programs have their working path's wront. Print out argv[0] from the main function and you'll see it is different.

One obvious solution would be to execute your program from the same directory as KDevelop.

]]> no-reply@allegro.cc (HoHo) Tue, 28 Nov 2006 02:06:29 +0000

Yeah, you need to do this:
niels@niels-desktop:~/Programmeer/C++/allegro2$ src/allegro2

]]> no-reply@allegro.cc (CGamesPlay) Tue, 28 Nov 2006 02:07:50 +0000

niels@niels-desktop:~/Programmeer/C++/allegro2/src$ allegro2

Worked,

But wont other people have trouble with running my future games, because they are not running it from home/niels/Programmeer/C++/allegro2/src ?

]]> no-reply@allegro.cc (BackwardsDown) Tue, 28 Nov 2006 02:21:22 +0000

Yes. The picture file needs to be in the same directory as the person running the program. In many cases, this is the same directory as the program. In others, this isn't, and you need to check in some other directory, for instance usr/share/games/allegro2.

Yay, you're great;D
