[Solved] Aeproject compile - connect ECONNREFUSED 127.0.0.1:3080

Hi,

I’m trying to compile a smart contract with aeproject. I have aeproject node running, but when I try aeproject node I’m getting this error:

Contract '/home/aepp/contracts/ExampleContract.aes has not been compiled'
connect ECONNREFUSED 127.0.0.1:3080

When I look into the docker ps, there is not any container listening at that port:

CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS                    PORTS                                      NAMES

Is there any error in the compiler?

I’m using
OS: Ubuntu 18.04
Aeproject: 2.0.1
Python: 2.7.15
Docker compose 1.25

Thanks

Did you start the compiler using aeproject compiler? (cc @martingrigorov.chain)

ups… nope. Sorry, my fault. I thought that aeproject compile directly started the neccesary containers, now is working. Thanks!

Other question, maybe is not for the post, buy I’m using a Lib “List.aes” to manage libs, and I’m include It with include "List.aes. When I use the online IDE it is automatically resolve, buy locally I’m getting this error:

File to include ‘List.aes’ not found. Check your path or it is from Sophia default library

How can include this file? Is there in any place on github?

Thanks

Hi @ialberquilla
Can you share your contract?

Thanks

Hi @alekseytsekov.chain,

Yes, is this:

include "List.aes"

contract TaskProjects =

  //Record for store the projects
  record project =
    { id             : int,
      creatorAddress : address,
      name           : string,
      description    : string,
      tasks          : list(int)}
   
  record task =
    { id            : int,
      projectId     : int,
      assignedTo    : address,
      name          : string,
      description   : string} 

  //State record
  record state =
    { projects       : map(int, project),
      projectsLength : int,
      tasks          : map(int, task),
      taskLength     : int}

  //Init function
  entrypoint init() =
    { projects = {},
      projectsLength = 0,
      tasks = {},
      taskLength = 0 }

  //Returns a project for a given id
  entrypoint getProject(index : int) : project =
  	switch(Map.lookup(index, state.projects))
	    None    => abort("There was no project with this index registered.")
	    Some(x) => x

 //Returns a task for a given id
  entrypoint getTask(index : int) : task =
  	switch(Map.lookup(index, state.tasks))
	    None    => abort("There was no task with this index registered.")
	    Some(x) => x

  //Register a new project in the blockchain
  stateful entrypoint registerProject(name' : string, description': string) =
    let index = getProjectsLength() + 1
    let project = { id = index, creatorAddress = Call.caller, name = name', description = description', tasks = []}    
    put(state{ projects[index] = project,projectsLength = index })

   //Register a new task for the given project
  stateful entrypoint registerTask(name' : string, projectId': int, description': string) =
    let taskId = getTaskLength() + 1
    let task = {id = taskId, projectId = projectId', name = name', description = description', assignedTo = Call.caller}
    put(state{ tasks[taskId] = task, taskLength = taskId })
    let project = getProject(projectId')
    List.insert_at(taskId, 0, project.tasks)
    put(state{ projects[project.id] = project })


  //Returns project lenght
  entrypoint getProjectsLength() : int =
    state.projectsLength

  //Returns taks lenght
  entrypoint getTaskLength() : int =
    state.taskLength

this issue should be fixed with the latest version of aeproject as far as I know (cc @martingrigorov.chain)

Hey @ialberquilla
With the latest version of aeproject your contract is compiled successfully. Maybe the info message is a little confusing and not telling that the contract is compiled with the included library. We’ll work on that to be more understandable.

File to include 'List.aes' not found. Check your path or it is from Sophia default library
Contract '/Users/path-to-contract/ExampleContract.aes has been successfully compiled'```

Hi @alekseytsekov.chain! Ok, thanks. I saw the warning a and thought that this file was needed, thanks!

The file is part of the standard library, and it is bundled with the compiler. There was a bug in how the standard library contracts was included, hence the problem. But it was resolved a while ago and with the latest versions it should just work.
