Comment puis-je exécuter un compilateur rapide Scala serveur distant?

Question

Je veux mettre un processus en cours d'exécution sur une fsc boîte que je peux alors accéder à distance.

Je comprends que je dois partager un répertoire temporaire.

Cependant, je me bats pour obtenir même ça va sur mon ordinateur portable.

Je suis en train:

fsc -Djava.io.tmpdir=/tempscala -server 127.0.0.1:8080

mais il me donne juste les options d'utilisation ...

Aide?

I think you're mis-understanding what fsc does. fsc starts a daemon process which stays alive between calls to compile, so it doesn't have to do all the initializing work each time. You can't actually run the compile on a completely separate box unless you have a shared file system.

As Jeha says, you should specify a temp directory with -D, then the scala files you wish to compile (this is why you're getting the usage instructions - it's missing a vital piece of information).

You also need to drop the -server, as fsc picks the port it's going to run on, and tells you it the first time you run it. You'll see lines something like this:

[Temp directory: /var/folders/oj/ojMgC8mDH4uK9fM5cjlK1E+++TI/-Tmp-/scala-devel/temp]
[Port number: 54056]
[Connected to compilation daemon at port 54056]

Then, when you want to recompile, you just call the same command again (still no need to specify server ports), then finally when you're done run fsc -shutdown
