module '_cqueues' not found

[konsumer]

I am trying to pak a small demo program that uses socket & http.request. Here is the demo-project. I am probably doing something wrong. I am sort of new to luarocks and luapak.

Here is the entry-point:

local socket = require 'socket'
local http_request = require 'http.request'

local server = assert(socket.bind('*', 0))
local ip, port = server:getsockname()

print('Please telnet to localhost on port ' .. port .. '. Give it a URL to download & run.')

function run(url)
  local headers, stream = assert(http_request.new_from_uri(url):go())
  local body = assert(stream:get_body_as_string())
  if headers:get ':status' ~= '200' then
    error(body)
  end
  local f = loadstring(body)
  return f()
end

while 1 do
  local client = server:accept()
  local url, err = client:receive()
  if not err then client:send('Downloading '..url .. '\n') end
  run(url)
  client:close()
end

It's just a small test of luasocket + http, really. I basically just want a bundled luajit + those 2 libs.

When I run this to pak it:

luapak make --lua-lib=/usr/lib/x86_64-linux-gnu/libluajit-5.1.so

I also tried:

luapak make --lua-lib=/usr/lib/x86_64-linux-gnu/libluajit-5.1.a

It says

Missing dependencies for rattata scm-1:
   http (not installed)
   luasocket (not installed)
   cqueues (not installed)

but all of those are installed (on my system) and the script works outside of luapak. After this, it builds things (it looks like it's building the things in the list) and finishes with no errors (and a lot of warnings)

When I try to run ./dist/rattata, I get this:

main:11384: module '_cqueues' not found:
	no field package.preload['_cqueues']
stack traceback:

	main:11835: in main chunk

It seems like it's not finding the native stuff it built. What am I doing wrong?

I tried being more explicit:

luapak make --lua-lib=/usr/lib/x86_64-linux-gnu/libluajit-5.1.a --lua-impl=LuaJIT --lua-incdir=/usr/include/luajit-2.1

with same issues.

luapak's directory-structure seems sensible:

Additionally, I tried using a pure-lua (via ffi) socket-library: https://github.com/CapsAdmin/luajitsocket

Here is my rockspec:

package = "rattata"
version = "scm-1"

source = {
   url = "https://github.com/notnullgames/rattata.git"
}

description = {
   detailed = "![rattata](https://cdn.bulbagarden.net/upload/thumb/4/46/019Rattata.png/500px-019Rattata.png)",
   homepage = "https://github.com/notnullgames/rattata",
   license = "MIT"
}

dependencies = {
}

build = {
   type = "builtin",
   modules = {
      rattata = "src/rattata.lua",
      ["src.ljsocket"] = "src/ljsocket.lua"
   },
   
   install = {
      bin = {
        "src/rattata.lua"
      }
   }
}

and it seems to be leaving out ffi.

Did you ever manage to work this out? Guessing not since there wasn't a follow up but I'm stuck on something similar, I have a few things building and working but once I introduced luasocket I ran into issues of not being able to load package.preload['socket.core'] at runtime, the build it self seems kinda healthy if I ignore all the warnings.

No, I ended up just not using luapak.

Thanks for the response! I think I should give up too but I'm not sure what my alternatives will be... possibly using a system Lua (locked to 5.1 so will cause other issues with cqueues 🙃).

Pretty stuck! Thanks again though, useful to know.
