[Fixed] (Mac) When I try to open or test something in the engine...

[MightyMerlinStyle]

...this happens.

Which version of OS X you have?
You would have no support of necessary version of OpenGL, minimum supported version is OpenGL 3.x. Later I will implement reserve rendering system to provide software render for systems where is no OpenGL or hardware render is shit (for example, video cards like ATI Radeon 9200 PRO and older which are has 128 MB VRAM and has no support of non-pow-of-2 textures).

Don't worry, SDL's software render gives ability to render had alpha-blending and most of OpenGL possible tricks are can be done with it

I have 10.10.5 (Yosemite).

That wired... Okay, I will apply something and then you can try to take nightly build to test it

[MightyMerlinStyle]

Okay, so I tried the new build from here, but I am still getting the error.

Not only that, but the editor now says I have an outdated configuration pack, even though I have the latest version...

Right, because new version has some updates in config pack and when I will felease it, I will update all configs too. I wasnt applied fix yet, I will notify you and when you can re-download that build again (it updating automatically every github commit)

[MightyMerlinStyle]

Oh, I just assumed since it was called a "nightly build", it would have been updated by then. Whoops!

I have the exactly same issue!

"Error initializing OpenGL! invalid operation" just after selecting a game ( I am trying with any of the 4 available SMBX configs)

My OS is El Capitan 10.11.2 and I am running a Hackintosh build with a Radeon 280 card, but every other game is working just fine!

So, wait, I will append some debug code into that place and message should be more detail. When I can fix issue

EDIT: Just added, wait ~45 min while PGE will be rebuilt, then redownload and tell me error which was been spawned (so, I would fix that)

[MightyMerlinStyle]

It's different this time.

MightyMerlinStyle, Thanks, now I know where look for a trouble. And trouble is: you are has OpenGL 3.2 while PGE Engine still use some legacy incompatible functions which I should remove to allow that. When I edited SDL's OpenGL Version to 3.2, I getting those errors myself, on Linux. Now I almost fixed that and so, next commit will contain a fix for OpenGL >3.1 and you will be able use PGE Engine right

[MightyMerlinStyle]

Thank you so much!

So I've been following this thread along, since I was having the exact same issues.
Now that you said you've fixed it I downloaded the latest nightly build and the error has changed again slightly.

Then after clicking OK:

After clicking OK again the error message closes and the engine window does too.

[Wohlstand]

Sorry, I wasn't fixed that error, because it is not an error:
PGE Engine tries to use OpenGL 3.1, but on the Mac OS X is a thing that if you will request OpenGL 3.x, really will be ranned latest OpenGL which you have on your Mac, OR will be ranned OpenGL 2.1.

Inside PGE Engine are used functions glEnableClientState(), glVertexArray(), etc. which are removed from OpenGL 3.2. New versions of OpenGL are completely uses shaders. So, I need a some time to upgrade my code to usage of the shaders. I will notify here when I will implement a fix.

Thanks a lot for looking into the issue! I will patiently wait for updates on this

[Wohlstand]

GOOD NEWS!
I finally implemented ability to use OpenGL 2 as backup render module, therefore on old video cards (which are has no OpenGL 3 and even has no support of non-pow-of-two textures!), and I finally fixed running on OS X (currently with OpenGL 2 usage, but I need to work more to resolve compatibility with OpenGL 3.2 and use modern OpenGL version on OS X)

Update in the laboratory

[MightyMerlinStyle]

Just saw this now, this is amazing! Thank you so much!
