OSWindowSDL2

I'm not a smalltalk expert, but from time to time I like to do some experiments.

Recently, we talked about making a small 2D-Game, to do something else than a traditional CRUD database application.

I downloaded pharo 4.0 for Linux (the default version). My OS version is 3.13.0-46-generic #79-Ubuntu:

Then I installed SDL2 with apt-get. All seemed to he OK.

I started pharo, and executed the following code in the playground:

|ex |
ex := SDL2Example new .
ex osWindow .

I got an error: Failed to find SDL2 library.
,

Should I have been doing some extra initialization to load the library in Pharo, or is there something else that I forgot to do?

Kind regards

Edwin

Re: OSWindowSDL2

Maybe the SDL version installed was 64-bit, and you need to 32-bit one.

Try something like
sudo apt-get install $LIB:i386

I presume...
$ sudo dpkg --add-architecture i386
is already done.

the support for SDL2.0 should be better in Pharo50 (even if due to ffi
changes and new objcte format we may have some
glitches).

cool
you can ask clement bera because he did a bomberman using SDL2 now I
guess that it was in Pharo 50.

Re: OSWindowSDL2

I downloaded Pharo5.

Re-executing

| ex |
ex := SDL2Example new.
ex osWindow.

now gives :

Subclassresponsability: SDL class has the responsability to implment #f

in the method

ffiLibraryName
self flag: 'HACK: avoid direct subclassResponsibility to not break RB test cases..'.
^ SubclassResponsibility signalFor: thisContext selector

Seems like I should have implemeted something myself.

Can any one point me in the right direction?

Re: OSWindowSDL2

yes, SDL2 is still not migrated (we changed FFI infrastructure).

I already have the fix, but I didn’t have the time to integrate it :(

Re: OSWindowSDL2

No problem. We will postpone the SDL experiment.

Traditions must be respected: we will try a small DB-application in the mean time. And after the first tries for the screen layouts, it seems there is no hurry...

Thanks already for your responses

You want to try this first with a non-spur pharo5.
(50496, e.g. from files.pharo.org/image/50-preSpur)
The current work on FFI is not yet announced to be
finished

Re: OSWindowSDL2

Hi edwin

if you use a prespur image you should get a pre-spur VM
Check
http://pharo.org/download
You will get the latest pre-spur VM and image.
Once esteban is done fixing the SDL in the latest Pharo you will be able to use
the latest vm.

Sorry guys,

I will watch out for the announcement of the official 5.0 version.

Thanks,
