Collector sweep failed at segment ROOT

[tukusejssirs]

@MRIIOT, I get the following error once a second using fanuc-driver (606fce3 + base-driver c129ffc):

2022/01/18 19:53:22.145|ERROR|[m1] Collector sweep failed at segment ROOT. System.DllNotFoundException: Unable to load shared library 'FWLIB32.dll' or one of its dependencies.

I use the following config.yml:

---
machines:
  - id: m9
    enabled: !!bool true
    type: l99.driver.fanuc.FanucMachine, fanuc
    strategy: l99.driver.fanuc.collectors.UseCase01, fanuc
    handler: l99.driver.fanuc.handlers.Native, fanuc

    broker:
      enabled: !!bool true
      net_ip: localhost
      net_port: !!int 8193
      auto_connect: !!bool true
      publish_status: !!bool true
      publish_arrivals: !!bool false
      publish_changes: !!bool true
      publish_disco: !!bool true
      disco_base_topic: fanuc
      anonymous: !!bool true
      user: null
      password: null

    l99.driver.fanuc.FanucMachine, fanuc:
      sweep_ms: !!int 1000
      net_ip: 10.14.7.18
      net_port: !!int 8193
      net_timeout_s: !!int 10
...

Can machines[id].broker.net_port and machines[id].['l99.driver.fanuc.FanucMachine, fanuc'].net_port have the same value (8193 in this case)?

Actually, it seems like I cannot make fanuc-driver work on Linux x64 after the config breakup (7cdbd59). On the other hand, I could not successfully build a7fa72e; and 1e7a3f9 had the collector initialization failed error.

However, I have a backup of a fanuc/bin folder (I have no idea from which commit it was built, but it is using the config before break up) which I can successfully run.

In the end, I wish I could run the latest fanuc-driver version without issues. I suspect it might be a hidden bug in fanuc-driver or my misunderstanding of the current config (after break up).

As for the Unable to load shared library 'FWLIB32.dll' error: wouldn’t it be easier to always use lowercase filenames? You know, on Windows FWLIB32.dll and fwlib32.dll refers to the same file, but on Linux (as per the default config, which is case-sensitive), they refer to different files. That said, I suspect that in this case, this is just a related thing, not the cause.

@MRIIOT, as a workaround, I want to try Ubuntu 16.04.6 LTS (last x86 Ubuntu version), however what is the difference between LINUX32_100 and LINUX32_105?

Update: I believe the number suffix means the library version used, i.e. 1.0.0 or 1.0.5. Is there any difference between the two?

Update 2: I could not install dotnet-sdk-3.1 on Ubuntu 16.04.3 LTS (the i386/32-bit package was not found).

        public static extern short pmc_rdpmctitle(ushort FlibHndl, [Out, MarshalAs(UnmanagedType.LPStruct)] ODBPMCTITLE a);

public class ODBPMCTITLE

needs to be declared for LINUX64, struct needs to be made explicit for x64
