[gemmacoswindow]: failed to init GLEW: your system only supports openGL-1.0

[rnkn]

Likely relate: #204

Sorry to say but I cannot get Gem to work on macOS 10.15.6 (19G2021).

I've compiled Pd from source @ 0.51-1 and launching as generated Pd.app package.

I've compiled Gem from source and installed as

make install libdir=$HOME/Library/Pd/ prefix=/Applications/Pd.app/Contents/Resources

This is what I get when clicking [create] in [gemmacoswindow-help]:

[gemmacoswindow]: failed to init GLEW: your system only supports openGL-1.0

I'm on a MacBook Pro (Retina, 15-inch, Mid 2015) with OpenGL 4.1.

Ancillary; I attempted to compile Gem from HEAD with ./configure --prefix=$HOME/Library/Pd; make install and load Gem as a library as instructed in the README, but this did not succeed in loading the library.

I've compiled Gem from source and receive the same error. Updated original post to reflect.

Similar to #257, if I first create [gemglutwindow] then [gemmacoswinow] it works... kind of.

[umlaeute]

so can't you use [gemglutwindow] as the backend for [gemwindow]?

[rnkn]

I did not think of switching out the default window. I recompiled with [gemglfw3window]. It works, except the video only occupies the lower left quadrant of the window. Would [gemglutwindow] be a better option here?

[umlaeute]

probably.
i would have expected the default ([gemmacoswindow]) to work, but we do have different backends in order to workaround problems on specific platforms.
[gemdefaultwindow] is a thin wrapper, so it's really easy to test different backends.

[rnkn]

Hmm changing [gemglfw3window] to [gemglutwindow] within [gemdefaultwindow] just crashes Pd. Think maybe it's a lost cause... 😕

[umlaeute]

dunno, does it crash if you change it on the fly (while having a gemwindow created)?
or does it also crash if you change it, then (re-)start Pd/Gem?
