Building Allegro 5.1 with cmake for MSVC 2008

Hi I try make a allegro5.1 project for Visual c++ 2008, by cmake.

It can't find libraries that I downloaded and I put in folders.

First I downloaded setup from, for example from here (libpng): http://gnuwin32.sourceforge.net/packages/libpng.htm
This file: Complete package except sources. And I installed it. Result?

#SelectExpand
1Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR) 2WARNING: libpng not found, disabling support

Okey, second try. I downloaded Developer files from same website and I put it in Visual include and lib folders.
Result? The same.

So, third half-lucky try: I found a path in cmake files for png headers: \usr\local\include\libpng
I put there png headers and it work, but just for headers. For libs I don't know what I should do. Anyway, result:

#SelectExpand
1Could NOT find PNG (missing: PNG_LIBRARY) 2WARNING: libpng not found, disabling support

Shows that headers are.

I believe the suggested method to compile this way is to put all of your include and lib folder contents inside a folder named 'deps' that you create in your allegro folder that you are building.

So you have :

allegro
   deps
      include
         headers
      lib
         .lib's

usr/local is for *NIX systems, I don't know why cmake would look there when generating an MSVC project. :-/

Thanks, it work. But I have some problem with the compiled allegro.

When I run my program, MSVC shows error:

#SelectExpand
1bool al_install_keyboard(void) 2{ 3 if (new_keyboard_driver) 4 return true; 5 6 //FIXME: seems A4/A5 driver list stuff doesn't quite agree right now 7 if (al_get_system_driver()->vt->get_keyboard_driver) { 8 new_keyboard_driver = al_get_system_driver()->vt->get_keyboard_driver(); 9 if (!new_keyboard_driver->init_keyboard()) { 10 new_keyboard_driver = NULL; 11 return false; 12 } 13 _al_add_exit_func(al_uninstall_keyboard, "al_uninstall_keyboard"); 14 return true; 15 }

in this line:

#SelectExpand
1if (al_get_system_driver()->vt->get_keyboard_driver) {

Allegro5.1 are compiled with 0 errors. But I downloaded dependences pack for allegro 4.9.8 from allegro.cc forum:
http://www.allegro.cc/forums/thread/599504/798701

Maybe it's a reason?

Did you call al_init before you called al_install_keyboard?

The dependent libraries you downloaded should still work, and you only have to link with them if you are static linking, or you use functionality from them. That's because the Allegro dll's have already been linked to them.

Yes. It's my program which work with allegro 5.0.3 binaries, but with 5.1 not.
I link new libs to project, and exclude 5.0.3.

EDIT:

I make project with new deps, that are downloaded by me, and still same problem with keyboard.

In MSVC bin folder I have only 5.1 dll's, that I compiled. And not work.

I'm not sure, but maybe it's because I compiled allegro with using WindowsJG it's a mod for XP. So maybe keyboard driver are - I don't know - avaliable by another way ???

The line it is crashing on indicates that the allegro system driver is probably NULL. That probably means al_init is failing to begin with. Build the debugging version of Allegro and link with that instead. That will give you an allegro.log file that may tell what is failing.

cd allegro\build
cmake -DCMAKE_BUILD_TYPE=Debug -G "Visual Studio 9 2008" ..

Nevermind, at now allegro5.1 work for me exclude al_uninstall_system(); I just removed it from my code :O
When new official binary come out I start to use this function.

Anyway, thanks.

Now I'm trying to understand shader addon.
