Apparently on a mac, starting gloss/GLUT crashes:

@pixln

Could you try the following:

git clone https://github.com/turion/essence-of-live-coding
cd essence-of-live-coding
nix-shell
cd essence-of-live-coding-gloss-example
cabal repl
:livelaunch

This should result in the same error.

Now to hopefully fix it, leave the REPL again and do this:

git checkout dev_forkOS
cabal repl
:livelaunch

This should give a window with 2 balls, and if you click in it, they'll start dancing. Does that work?

We tried additionally to replace further occurrences of forkIO by forkOS, to no avail.

Hmmm, strange. It seems like the flag didn't have any effect, since you still have "GLUT Fatal Error". But with this flag, GLUT shouldn't even run. I probably got the way these flags work wrong. Can you execute cabal configure --constraint 'essence-of-live-coding-tutorial glfw', and then try cabal repl?

I got the command wrong again I think. cabal configure --constraint 'gloss glfw', and then try cabal repl.

Adding the constraint gloss +glfw -glut seemed to work for cabal run, but not for cabal repl.

@pixln Can you try cabal repl -- constraint="gloss +glfw -glut"?

turion commented Aug 22, 2020

Also, the flags might have to be upper case, +GLFW -GLUT.

A further option to try is executing cabal install gloss --flags="GLFW -GLUT" first.

@pixln I got help from @hvr, who suggests to do:

cabal repl --constraint "gloss source" --constraint "gloss +GLWF -GLUT"

Can you try that?

@thielema

cabal repl --constraint "gloss source" --constraint "gloss +GLWF -GLUT"

Never knew this syntax. Looks like advanced Cabal usage.
So far I use a cabal sandbox, and I guess nix-style local builds plus a cabal.project file would work too.

I guess "GLWF" should be "GLFW"?

Still doesn't work for me:

@jegi Sorry this didn't work out for you :/ lesson definitely learned - OpenGL dev environments are hard to set up cross-platform.

No problem. Thanks for the tutorial anyway! I'd like to be able to use something like this for teaching, but the infrastructure doesn't seem to be ready for primetime yet.

@jegi Gloss is indeed hard to set up reliably. But essence-of-live-coding itself is completely portable. It's just the backends that work better or worse in different platforms. Is it 2d interactive graphics that you want to teach, or live coding itself? For the latter I think that it works well cross-platform.

@jegi For what it's worth, someone else did indeed get the tutorial running on a mac: https://groups.google.com/g/haskell-gloss/c/qHkFOAA2VCY/m/NANJrbsbCAAJ If it's specifically Gloss you're interested in, probably we should ask on the Gloss mailing list.

jegi commented Aug 24, 2020

It was mainly 2D interactive graphics. Livecoding would be a nice touch. But I'd like the materials to be reliably usable by the students on whatever platform they have at home.

I see. Well, I believe Gloss's mission was to provide just that.

Has anyone had success with this on mac more recently? The live coding runs great out of the box, and gloss works with cabal run, but ghcid quits with

ghcid: Command "cabal repl" exited unexpectedly with ExitFailure 1

(Presumably related to the fact that you can't run gloss in ghci?)

Ah, this is known? Sorry, so far there is no alternative to GHCi in essence-of-live-coding.
