Hi,

After failing with the latest subversion sources, I was finally successful in compiling a MacOS browser plugin based on the VMM38b4 sources. However, I can't get OpenGL to work. I've traced the problem to sqMacOpenGL.c. The call to GetWindowGreatestAreaDevice() fails with an error code of -5600 ("Invalid Window Pointer"). I assume that this is because getSTWindow() doesn't work when Squeak is running in a browser plugin.

I hacked it by avoiding all the GDH stuff if we are in a browser, like so:

#ifdef BROWSERPLUGIN

swAttrib[2] = 32;

#else

#ifdef INTERNAL

#if TARGET_API_MAC_CARBON

DPRINTF(5, (fp, "Getting GDH (Carbon): %d\n", getSTWindow(), flags));

stat = GetWindowGreatestAreaDevice(getSTWindow(),kWindowContentRgn,&tempGDH,&ignore);

if (stat) DPRINTF(1, (fp, "ERROR: failed call to GetWindowGreatestAreaDevice (code: %d)\n", stat, flags));

#else

DPRINTF(5, (fp, "Getting GDH (non-Carbon)\n", flags));

tempGDH = getDominateDevice(getSTWindow(),&ignore);

#endif

if (tempGDH == nil) {

DPRINTF(1, (fp, "ERROR: tempGDH is nil (whatever that means)\n", flags));

return -1;

}

swAttrib[2] = (*(*tempGDH)->gdPMap)->pixelSize;

#else

swAttrib[2] = (*(*GetMainDevice())->gdPMap)->pixelSize;

#endif

if(swAttrib[2] < 16) swAttrib[2] = 16;

#endif

Obviously, this is crap, but I don't know the right thing to do.

Anyway, this allows me to successfully create an OpenGL context ("OpenGL newIn: aRect"). Adding an external FFI plugin to the browser plugin directory lets me make OpenGL calls. But something is still wrong: it seems like the OpenGL buffers are never swapped (although DPRINTF assures me that they are: "### Swapping renderer buffers").

I've had enough of this for tonight; I need some sleep. But in the meantime, I'll take any advice I can get (eg: "stop working on that, the latest sources will do everything you need RSN").

Thanks,

Josh
