Homebrew RELEASE libcross2d: a little cross platform 2d library

[cpasjuste]

I'm having issues building on linux for linux. I've opened an issue on github in the examples repo.

Hi @minkcv, may i ask you your distribution and version? I tested it on a stock/vanilla ubuntu 18.04 installation and didn't notice this problem (you did install deps i guess? :
sudo apt-get install build-essential cmake git libsdl2-dev libfreetype6-dev libglm-dev)
@hippy dave, do you have a patch for macosx?

@hippy dave, do you have a patch for macosx?

Yeah I can supply the modified cmake files, but like I said, I bodged it a bit to get around the sdl module not found issue, so maybe will see how that pans out.

I just did a fresh install of Debian 9.6 and it builds now, but segfaults on the texture example.

In the output I see:
Couldn't SDL_GL_CreateContext: Could not create GL context: GLXBadFBConfig

I can post the full output if you would like.

Hi @minkcv, what is your graphic card? (and maybe your debian window manager: gnome, kde...). I'm going to give it a try.

@minkcv , the problem may be the videocard or driver, could you install mesa-utils (apt-get install mesa-utils) and do: glxinfo | grep OpenGL

I'm using Intel integrated graphics on this machine. I've run glxinfo and I have opengl. glxgears works as well. I chose cinnamon as my window manager.

The output of the glxinfo I pasted will give more info (like your opengl version). I do also have an Intel card and its working.

Ok. I'll post my glxinfo output when I get home.

@cpasjuste What is your glxinfo output?

 

[cpasjuste]

Your graphic card or driver may be the problem (my card/driver can do 4.5 opengl core profile while your's only 3.3. Also, you're using a pretty old version of mesa it seems).
Here is my output:

Can you post the result of this: lspci | grep VGA

Else, it would be cool if you could test changing one line in libcross2d, replace 4 with 3 (so you use a 3.3 core profile).: https://github.com/Cpasjuste/libcro...ource/platforms/sdl2/sdl2_gl_renderer.cpp#L27

I think it should work fine. I will lower down this requirement (use 3.3 core profile) for linux...

Changing that version number in the code fixed the issue and it works now. Thank you

Holy crap huge project man, congrats on the release.

Hi @minkcv , i update libcross2d-examples with the latest fix from libcross2d, which include the opengl context change (use 3.3 core profile instead 4.3), so you won't have to "hack" it everytime you update libcross2d.

@cpasjuste Thank you. Should I use libcross2d as a git submodule in my project?

Yes, exactly, so you can easily update it from time to time. Also, don't hesitate to ask for new features.

Could you include the ConvexShape class from sfml? I'd like to create shapes from points.

Yes sure! You can easily derivate from the shape class thought. I'll take a look tomorow.

I was able to get it working with the sfml code. I created a pull request on GitHub.

Nice, I'll take a look tomorrow (Thanks for the PR!)
