The answer, is "yes" to both questions.
Come back if you have any problems.

And is synaptic package manager enough to remove the not working version?

The answer to both questions is 'yes'...if done correctly.

To compile you'll need to install "build-essentials"...plus any development libraries and cruft creators.

...but the deb package for OpenCPN (with the right libraries as mentioned) should do it without the wailing and gnashing of teeth. I don't know why the deb doesn't list them as dependencies and enable Synaptic (or some-such) to d/l them.

Hi,

Unfortunately, your CMake version is outdated. You can try to download FindGTK2.cmake in your build directory, then run cmake again. Here's the latest version:
http://cmake.org/gitweb?p=cmake.git;...4ff4efb80a09fa

If that doesn't work, you'll need to update cmake. You can download and run cmake-2.8.3-Linux-i386.sh from
CMake - Cross Platform Make

Regards,
Jean-Eudes

Glad you made, finally.
I used your experience to tweak the Linux instructions a bit.
*It's not necessary to name libgps as gpsd will pull the correct libgps version..
*cvs gone, not used anymore.
* Now stating min version of Ubuntu & Fedora that includes Cmake 2.8. Sorry I missed this in my answer to you!

I just started with ubuntu on an old laptop. Installed the latest version (10.10) last evening.
Today, I downloaded the latest released version of ocpn for ubuntu: R2.1 : I followed strictly the ocpn home page instructions. It installed, but I could not open it.
Help in the matter would be really appreciated, but I am not a SW expert at all, and any suggestion or request for more info should be completely detailed. For example, if you want to see a log file, please specify which one and where I will find it, etc...

Thank you

Here is the trick, for all of you non SW experts who have problems starting opencpn on ubuntu:
go to: system -> administration -> synaptic package manager
click on "search", enter "opencpn". If you have installed it, it will appear marked as installed. right click on it and select "properties", then click on "dependencies".
Write down exactly each dependency listed. Now, do a similar search for each dependency and check that it is installed. If not, mark it for installation. When you are done, click "apply" on the main synaptic screen. When all is done, go back to : applications -> other -> opencpn and it will open!

Why can't you SW gurus give us this kind of simple and logical recipe iso these impossible command lines that never work for me?

Good job working that out claire. Normally the dependencies are pulled automatically when you install opencpn? Bit annoyign that..

Thanks for posting your experience. It made me look a bit closer at the instructions on the wiki, and test Ubuntu from the install CD, to see what's going on, on a new install.
My conclusion is that the instructions missed an essential step. The "universe" repository must be made available before even trying to install OpenCPN, otherwise the necessary libwxgtk2.8-0 will not be installed. Unfortunately this repository, is not activated by default, when installing Ubuntu.
I have changed the instructions accordingly. I hope that this will solve the problem for first time installers.
