I am having the same problem. I loaded opencpn_2.1.624l_i386.deb in a newly installed Ubuntu and am unable to start it. It used to work on my previously upgraded Ubuntu version,04.10 but not with the fresh install.

computer@computer-laptop:~$ opencpn
opencpn: error while loading shared libraries: libwx_gtk2u_core-2.8.so.0: cannot open shared object file: No such file or directory

Running Ubuntu 10-.04

***********************************

Found the solution. It appears that libwxgtk2.8-0 libraries are required.

$sudo apt-get install libwxgtk2.8-0

will do the trick - it did for me.

On version 2.1.0 (built 624a) when activating LIBGPS client library, opencpn searches for the wrong lib name. Can be check with: strace -e open -o !"grep libgps" opencpn

OpenCPN looks only for "libgps.so" when on 10.04 the library name is "libgps.so.19". A quick fix is to add a link with: sudo ln -s /usr/lib/libgps.so.19 /usr/lib/libgps.so

Obviously it would be nicer if "dlopen" call was checking for the most up to date version of the library. Today it is so.19 but tomorrow

Outside of that it works perfectly.

I believe it is traditional for the soft link to be made automatically by the library installer, whatever that may be.
Or, it is expected that the user should run

ldconfig

after loading a new library version.

This is done so that updates from ...so.19 to ...so.20 do not require the affected applications to be recompiled.

Wonder why the link was missing from 10.04?

Thantks FuzzyFeat, that did the trick I think! Anyway, it booted.

Sorry for the silent, I was on the water

LDCONFIG is useless in this situation. It only updates /etc/ld.so.cache which hold location of shareable libraries, but in no case builds equivalence in between short name without version and a full name which version.

For the link in between .so and .so.19 while very common it is not systematic any more. The main problem with this link is that it make difficult if not impossible to have two versions of the same libraries, as a result in many cases this symbolic links does not exist any more, and software search for a library that is at least as hight as so.xyz, which unfortunate is not handle automatically by "dlopen" call.

One option would be OpenCPN's installation script to check for this .so library and to built a link in case it does not exist. Adding few lines in the installation script might be the easiest option.

Hi
I have got OpenCPN running nicely on my laptop under Ubuntu 10.04
Had to move my NMEA data source to: /dev/ttyUSB0.
My charts are old Canadian Hydrographic Service BSB3 charts and have several large scale inserts which I cannot get displayed.
For example CHS chart 3668 is a file called 3668.BSB and then there are some .KAP files that I think go with it 366801.KAP through to 366804.KAP
Would welcome some advice from someone more knowledgeable
