Description Mike 2016-05-11 00:33:50 UTC 
Hello,

I'm getting the following error when I try to use rgl:

No matching pixelformats found, perhaps try using LIBGL_ALLOW_SOFTWARE
Abort trap: 6

The following tips in bug 92640 https://bugs.freedesktop.org/show_bug.cgi?id=92640 didn't help.

I tried replacing my 2.7.8 libGL.1.dylib 2.7.7 and vice versa.

I also tried replacing 2.7.8 /Applications/Utilities/XQuartz.app/Contents/MacOS/X11.bin with 2.7.7 version.

None of these worked for me.

Any help would be much appreciated.

Thx,
Mike

I don't know what rgl is, but try setting LIBGL_ALLOW_SOFTWARE as instructed.  You might not have any supported configs in whatever mode you're running.

Yup I figured it out.

I had to set the environment variable LIBGL_ALWAYS_SOFTWARE=1.

In R the command is:

Sys.setenv(LIBGL_ALWAYS_SOFTWARE=1)

Thanks.
