O5 Linux in Ubuntu 18.04LTS for Windows10

[sailorF54]

Linux on Windows 10 does work for opencpn !
(Ubuntu 18.04, at least with W10 1903)
with xfce4 and an Xming server
However a dual boot Ubuntu is the way to go !

[sailorF54]

Full setup...

[sailorF54]

Compiling, running and displaying O is fine !

It depends. With dual boot I can’t run Windows and Linux programs at the same time. But with WSL it’s easy. I have really grown to like WSL. It’s powerful, fairly complete and well supported. Linux programs in WSL run as fast or faster than in a dual boot system.

Since GTK seems to be one problem https://www.gtk.org/download/linux.php


Do I install one from gtk.org? If so, which one?
or

https://launchpad.net/ubuntu/+source/gtk+3.0 ?


Also I haven't installed a compressed package yet. Uncompress and then execute?


I am going to try to xrdp. I looks fairly involved but it is all sudo commands.

[rgleason]

BTW I did

rgleason@Dart:~$ dpkg -l libgtk[0-9]* | grep ^i
ii libgtk2.0-0:amd64 2.24.32-1ubuntu1 amd64 GTK+ graphical user interface library
ii libgtk2.0-bin 2.24.32-1ubuntu1 amd64 programs for the GTK+ graphical user interface library
ii libgtk2.0-common 2.24.32-1ubuntu1 all common files for the GTK+ graphical user interface library

Rick,

Don’t install anything except via sudo apt. Don’t add any extra PPAs except for OpenCPN.

Most of the blogs you read are wrong. Everything needed is available from the regular PPA that installs with WSL from the App Store. You don’t need to doctor up the PPA. That will just lead to heartache.

OK Transmitterdan, you're right
Using xrdp is much better than using Xming
However VNC on W10 seems to enter an infinite loop when connecting

Using W10 integrated app works fine

Yes, pointing a VNC client to its own display is like pointing a video camera at its own view screen. It becomes an infinite set of mirrors.

That's great to know, but how do I install it using sudo commands? What directions and version of XRDP should I be installing?

Regarding xrdp This does not appear to be the way to install it https://github.com/neutrinolabs/xrdp/releases
I need to use sudo apt.

Is this the right place to start executing commands?

Regarding the second problem, installation of GDK+ what version do I need and how should I install it? [no launchpad please, just using sudo apt, as per TDan]

rgleason@Dart:~$ export DISPLAY=:0.0
rgleason@Dart:~$ opencpn
ALSA lib confmisc.c:767parse_card) cannot find card '0'
ALSA lib conf.c:4528_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory
....

ALSA lib pcm.c:2495snd_pcm_open_noupdate) Unknown PCM dmix

20:23:51: Error: Unable to initialize GTK+, is DISPLAY set properly?

rgleason@Dart:~$ dpkg -l libgtk[0-9]* | grep ^i
ii libgtk2.0-0:amd64 2.24.32-1ubuntu1 amd64 GTK+ graphical user interface library
ii libgtk2.0-bin 2.24.32-1ubuntu1 amd64 programs for the GTK+ graphical user interface library
ii libgtk2.0-common 2.24.32-1ubuntu1 all common files for the GTK+ graphical user interface library

So it does have libgtk2.0-0 , gtk 2.0 but that's not good enough for OpenCPN?

I started this thread to establish the steps necessary to complete this install such that I could run Opencpn in linux. It is useful to know that you "can" do things, but right now, for me, the question is "how"?

I have
1. Changed windows settings to enable WSL "Windows System Linux"
2. Installed from Windows Store the App "Ubuntu 18.004LTS"
3. Installed the PPA for Opencpn.

That is it. I don't want to make false moves and have to start over, although I could try that "black box, dumb monkey" approach.

While you're apt-getting....... why not install signalk for a play?

Rasp Pi worked for debian though couldn't get avahi working, the server still works though.

Open the Ubuntu terminal. Then run:

sudo apt install xrdp xfce4 openssh-server
sudo service xrdp start
sudo service ssh start

You don’t actually need ssh but it can be handy especially if you run WinSCP on Windows.

Also, from the OpenCPN developer’s manual:

sudo apt-get install build-essential cmake gettext git-core gpsd gpsd-clients libgps-dev wx-common libwxgtk3.0-dev libglu1-mesa-dev libgtk2.0-dev wx3.0-headers libbz2-dev libtinyxml-dev libportaudio2 portaudio19-dev libcurl4-openssl-dev libexpat1-dev libcairo2-dev libarchive-dev liblzma-dev libexif-dev libelf-dev libsqlite3-dev

Then:

git clone https://github.com/user/opencpn.git (use your github username in place of “user”.

cd opencpn
mkdir build
cd build
cmake ..
sudo make install

After that finishes start Remote Desktop Client in Windows. Connect to Computer:

localhost:3389

Use the same username and password you used for Ubuntu for Windows.

Do not use dpkg, tarballs or other packages of unknown provenance.

Thank you TDan for all the help. It was surprisingly easy, but would not have been, if it were not for your guidance. I'll make a page in the manual for this and hope others will advise and augment it.

I found the Ubuntu files under

C:\Users\[User]\AppData\Local\Packages\CanonicalGroupLimited.Ubun tu18.04onWindows_...

and it occupies just 950mb!

Rick,

The names and locations of these files move around. Don’t access the Linux files using Windows Explorer. You can do some harm to the Linux file system by writing a file to those Canonical folders.

The simplest way to access Linux file system from Windows is using a tool called WinSCP. It is sort of like Explorer as it can safely transfer files between Linux and Windows. But Windows Explorer does not fully understand the Linux file system.
