Unable to run examples? about lambdacube-edsl HOT 7 CLOSED

Actually, ignore this. I was trying to set it up from scratch, but I'm not able to get the "getting started" examples to work at all, so this comes later.

after a successful

cabal install lambdacube-gl
cabal install GLFW-b

Compiling Hello.hs leads to

Hello.hs:14:8:
    Could not find module ‘Paths_lambdacube_samples’
    Use -v to see a list of the files searched for.

I'm not sure where the module is being defined. Can I have some help?

from lambdacube-edsl.

Oh, you're looking at the samples for the old EDSL system, which are not compatible with the new GL backend. Check the examples directory within lambdacube-gl (as the getting started guide suggests just above the screenshot), which should work as advertised.

Okay, new error now. I'm following the getting started guide, at the point where i'm supposed to build Hello.hs

[1 of 1] Compiling Main             ( Hello.hs, Hello.o )

Hello.hs:20:26:
    No instance for (FromJSON LambdaCube.IR.Pipeline)
      arising from a use of ‘decodeStrict’
    In the first argument of ‘(<$>)’, namely ‘decodeStrict’
    In a stmt of a 'do' block:
      Just pipelineDesc <- decodeStrict <$> SB.readFile "hello.json"
    In the expression:
      do { Just pipelineDesc <- decodeStrict
                                <$> SB.readFile "hello.json";
           win <- initWindow "LambdaCube 3D DSL Hello World" 640 640;
           let inputSchema = makeSchema $ ...;
           storage <- allocStorage inputSchema;
           .... }

It looks like de-serialization isn't happening?

if you use it from github then try to install it with -fexample

cabal install -fexample

from lambdacube-edsl.

Nope, I'm installing it using Cabal (hackage). Same error, unfortunately. Any idea where it might be going wrong?

from lambdacube-edsl.

The -fexample flag will be included in the next release, it's not yet on the hackage version of lambdacube-gl. You have to work from gtihub for now.

install

git clone https://github.com/lambdacube3d/lambdacube-ir.git
cd lambdacube-ir; cabal install; cd ..
git clone https://github.com/lambdacube3d/lambdacube-gl.git
cd lambdacube-gl; cabal install -fexample

run

cd examples; ../dist/build/lambdacube-gl-hello/lambdacube-gl-hello

from lambdacube-edsl.

Thanks a ton for the detailed instructions! I got it up and running :) Really appreciate it.
