Fine Offset + Linux Mint

[steve]

Could you please tell me what version of mono you have, and whether it includes Mono.Posix, and what kernel version you are running?

Please also paste the output from the attached updated test program.

Linux 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:30:01 UTC 2014 i686 i686 i686 GNU/Linux

No idea on how to check whether I have Mono.Posix or not. I do have its DLL on /usr/lib/mono/4.5/


New USB test:

Aha. So you need to install package libudev-dev at a guess.

[mcrossley]

Is this any help? Running 32 bit programs on 64 bit Linux can cause this error...

[Spider-Vice]

Unfortunately I still have the same error after installing libudev-dev.

@Mark: My Linux Mint is 32-bit.

[steve]

Perhaps you have libudev.so.1 rather than libudev.so.0 - Google suggests this is a common problem. Possibly resolved by installing package libudev0.

[Spider-Vice]

Followed this (http://www.unixmen.com/resolve-libudev0 ... ntu-13-04/) advice and the USB test app now detects something!

Code: Select all

And according to diags, it has successfuly recognised the FO station and it is working successfully now!

I'm pleased you have it working, but the instructions in that link are a bit scary - you're apparently installing a package from a dropbox account? Is there no official source?

[Spider-Vice]

Yeah, I know, but apparently it is indeed the real libdev0 package, it's just an older version. There probably is a way to add an official repository though.

Edit: Official Ubuntu link: http://www.ubuntuupdates.org/package/co ... s/libudev0 The download links are from Ubuntu's servers. (security.ubuntu.com)

[mcrossley]

does "apt-get install libudev0" not work? On my Pi (Debian) it says it is already the latest version.

[Spider-Vice]

It said something about being located in a different source and didn't download it.

[Buford T. Justice]

Could you please unzip the attached on your Linux system, then change to the directory in a command window and type:

mono HidSharp.Test.exe

and paste the output here.

mono HidSharp.Test.exe

I also installed libudev-dev but that didn't work.

I THINK I FIXED IT!!!

In Ubuntu and it's derivatives for 14.04 Trusty Tahr, in both /lib/x86_64-linux-gnu and /lib/i386-linux-gnu there is a link file called libudev.so.1 which links to libudev.so.1.3.5. I decided the hell with it and made another link file in both locations called libudev.so.0 by right-clicking on libudev.so.1.3.5, making a link, and then renaming the link file. I fired up CMX and data is being displayed. IT'S ALIVE!!!

[Hunter362]

I was having the same exact problem, CMX ran fine on a laptop that was *upgraded* from Ubuntu 13 to 14.04
libudev.so.0 is not available in 14.04, but must have been installed sometime prior, thus CMX ran fine on my laptop.
So following Bufords post I did the same,

cd /lib/x86_64-linux-gnu/
sudo ln -sf libudev.so.1 libudev.so.0

And she works!! To clarify, CMX started fine, but could not find the Fine Offset station.

Also could not get CMX to run using mono 2.10.8.1 Ubuntu 12.04
Running on Ubuntu 14.4 with mono 3.2.8

I'll keep checking posts, just got excited that I finally got it working and displaying!
Question, in Cumulus 1 you have the option to copy the files to the web directory rather than ftping them, I want to run this on the same machine
thats hosting my website, I don't see that copy option in CMX

It's exactly the same in MX, you put a file name in the 'remote' box and don't tick 'ftp'. Where is the option that you think is missing?

[mcrossley]

cd /lib/x86_64-linux-gnu/
sudo ln -sf libudev.so.1 libudev.so.0

I did read somewhere in my Googling on this when it first came up that libudev0 and libudev1 are not the same beast (hence the different names ) and whilst creating a cross link may work for some things, it may break others, and is generally considered a bad idea.
