IOSurfaceDecrementUseCount is 10.6+ (and apparently still missing in the early 10.6 on powerpc): https://developer.apple.com/documentation/iosurface/1419377-iosurfacedecrementusecount

The type should be CGRect? Given it is 10.0+, supposed to be identical across all macOS versions: https://developer.apple.com/documentation/coregraphics/1454845-cgcontextdrawimage

[bugaevc]

Indeed, so that takes a CGRect, not an NSRect; I wonder how it built on newer systems. All of IOSurface is 10.6+, so we're going to need to disable it for 10.5.

[bugaevc]

The other thing about IOSurface is I never made a full EGL implementation based on it / OwlIOSurfaceBuffer; if you happen to be proficient in GL, it'd be great if you could work on that.

[barracuda156]

All of IOSurface is 10.6+, so we're going to need to disable it for 10.5.

On 10.5 there is also no libdispatch (and I could not make it build from source on Leopard either: the port is there, it builds and seems to work fine on 10.6 ppc, but fails on 10.5; perhaps gcc-4.2 lacks something in 10.5.8, even though it is nominally released after the one of 10a190, maybe also Libc if not the kernel needs to be rebuilt to support libdispatch).

The other thing about IOSurface is I never made a full EGL implementation based on it / OwlIOSurfaceBuffer; if you happen to be proficient in GL, it'd be great if you could work on that.

Unfortunately, no, I am not.

@RJVB Tagging you re EGL.

[bugaevc]

On 10.5 there is also no libdispatch

I had to drop most of libdispatch usage when making it build on GNU/Hurd anyway. What's left is some in OwlMIG.m; that should be rewritten anyway.

[barracuda156]

BTW, a stupid question: how to pass two flags at a time? However I pass those to environment, only the first is actually used and another one discarded.

[bugaevc]

Do you mean the flags for a C compiler? Just the following should work:

$ CFLAGS='-foo -bar' ../configure

only the first is actually used and another one discarded.

At which stage? Do you not end up with CFLAGS = -foo -bar in the generated Makefile?

[barracuda156]

Thank you, I will try.

By the way, I got this configure failure now:

Passing flags this way (via configure.cmd-prepend) worked. Rosetta config error I manually patched out for now, but with this we are stuck:

It is not just libdispatch, it is also using blocks – this won’t compile with gcc, any version of it (until its upstream finds time to add support into the compiler).

Unfortunately, no, I am not. @RJVB Tagging you re EGL.

Saying I'm proficient in GL would be a huge overstatement, saying "I'm EGL" simply wrong. I've gotten Mesa to build a working software EGL driver but apart from that I'm not even certain what EGL really is and if it would be feasible to make a sort of hybrid EGL implementation that uses native OpenGL where possible to get *some* acceptable performance. Software/CPU EGL is fine for simple/small-scale UI effects or for remote rendering where you don't expect fluid graphics anyway, but really not ideal as the main engine for all local rendering.

[RJVB]

I had to drop most of libdispatch usage when making it build on GNU/Hurd anyway. What's left is some in `OwlMIG.m`; that should be rewritten anyway.

FWIW, I think there is a bug with thread-local storage in the posix/pthreads layer on OS X that leads to memory leaks, but not in libdispatch.

That's a simple ObjC file, not ObjC++ . IIUC that means there should be less risks with going from an Apple Block to an enclosure ("lambda" function) or in this case, a function pointer. You're installing an event handler here, so the handler code is *probably* called synchronously whenever an event occurs, rather than async on a separate thread. The code doesn't compile with Apple's GCC which did have blocks support IIRC?

Well, with dispatch there is an issue that we just do not have it on 10.5 (I tried, but it does not compile there, in fact it failed even on 10a190 i386, ironically; it only works on 10.6 ppc), and blocks are out of question until Iain fixes that in gcc.

But pthreads do have issues, I agree with you.

Do you recall some example where that was done? I just never dealt with this.
