This could mean a few things... - "basic" still uses "simulator.rkt" and not "tablet.rkt" - The "raco ctool" uses a different version of Racket than was built for Android - There's another exciting error (we'll have to look at the Android logs) > This is on a Sony Xperia Z2 cellphone running CyanogenMod 12.1 (Android > 5.1.1).

Can you give me more info about the GPU, driver, OS, etc that you have? If you open up `mode-lambda/backend/gl/util.rkt` and go to the definition of `print-shader-log`, then you can add the following line at the bottom of the function (error 'print-shader-log "Shader/program compilation/linking failed without error message") If that happens, then I think I know where I go to debug some more, but I'll need to send you more patches Jay -- Jay McCarthy Associate Professor PLT @ CS @ UMass Lowell http://jeapostrophe.github.io "Wherefore, be not weary in well-doing, for ye are laying the foundation of a great work.
