    Script errors after conversion from Windows to Linux

    Hello all,

    I have been trying to figure this out for a while but I cannot get any further. After moving a working script from Windows to Linux i'm getting all sorts of errors. I read through the forum and was able to fix some of the common errors (implicit declarations etc) but i'm still stuck with these errors and I have no clue what they mean
    Apr-13 9:21:53 PM Error Compiling script /opt/HomeSeer/scripts/waterfurnace-errors.vb: CHANGEME
    Apr-13 9:21:53 PM Error Compiling script /opt/HomeSeer/scripts/waterfurnace-errors.vb: 42021
    Apr-13 9:21:53 PM Error Compiling script /opt/HomeSeer/scripts/waterfurnace-errors.vb: 42021
    Apr-13 9:21:53 PM Error Compiling script /opt/HomeSeer/scripts/waterfurnace-errors.vb: The import 'System.Core' could not be found.
    My script reads some data from a furnace and creates a HTML email with some status information. The same code is used in another script to update HS objects but I haven't yet had the time to go and fix that script (similar errors). I believe the errors are caused by the return values from the functions (I marked the error point with **HERE** below) as even if I comment out all lines in the function Geo_Read i still get the same errors. Can anyone spot what I am missing?

    Your Geo_read function is returning an array in some cases. I have found that mono-vbnc has a hard time with some aspects of array handling.

    See https://forums.homeseer.com/forum/de...bnc-deprecated

    Unfortunately, while mono-vbnc is deprecated, the scripting mechanism that HS uses hasn't been updated by the mono developers to use the more modern vbc compiler.

    A possible workaround is to patch mono to call vbc instead of vbnc. Here's how to do that from the Linux command line

    Code:
    sudo mv /usr/bin/vbnc /usr/bin/vbnc-orig
sudo cp -a /usr/bin/vbc /usr/bin/vbnc

      OK I made the changes you suggested but now I get different errors. Any thoughts?

        The 1st & 3rd message are just warnings; the 2nd is a real error. It's because your Geo_Read function returns an array of strings,

        Dim strSplit() As String
        ...
        Geo_Read=strSplit

        But the call expects a simple string

        Dim Geo1 As String
        Dim Geo2 As String
        ...
        **HERE** Geo1 = Geo_Read("IP_ADDR1")
        **HERE** Geo2 = Geo_Read("IP_ADDR2")

        I don't know what the data format looks like, but just guessing you want just the first entry of a comma separated list, change the line

        Geo_Read=strSplit
        to
        Geo_Read=strSplit(0)

          strSplit is an array of values that are pulled from the furnace. Array positions 0-100 have values in that represent the counts of particular errors.

          Within the function Geo_Read I connect to the furnace and then populate the array strSplit. The line Geo_Read=strSplit returns the values in the array back to the array Geo1 or Geo2 which is then used to create a combined report.

          So to answer the question I don't just want strSplit(0) but strSplit(0) to the of the array

          I really appreciate your help here. Any additional thoughts?

            In that case, you'll need to change back the declarations of Geo1 & Geo2

            from

            Dim Geo1 As String
            Dim Geo2 As String
            ' Dim Geo1(100) As String
            ' Dim Geo2(100) As String

            to

            'Dim Geo1 As String
            'Dim Geo2 As String
            Dim Geo1(100) As String
            Dim Geo2(100) As String

                I had to rebuild my linux machine and copied over homeseer but now I don't seem to have a /usr/bin/vbc

                # ls /usr/bin/vbc*
                ls: cannot access '/usr/bin/vbc*': No such file or directory

                I have vbnc (and vbnc2)

                # ls /usr/bin/vbnc*
                /usr/bin/vbnc /usr/bin/vbnc2

                Any thoughts? I don't remember doing anyhing special to get /usr/bin/vbc to appear

                  I seem to remember having to download from the mono project site direct:

                    That is actually the version i am using

                    mono-complete is already the newest version (6.8.0.105+dfsg-2)

                      Ah - the UBUNTU:LATEST tag seems to have been elevated to focal (20.04). I set back to bionic (18.04) and all is good again.
