cmake fails under Linux

[falko]

I'm tried to build under Linux using the following commands:

mkdir build
cd build
cmake ..

and got the following error:

-- The C compiler identification is GNU 5.4.0

I already tried to install wxWidgets packages, but nothing changed. Any ideas?

Did you install wxWidget devel packages 3.0.X? I ended up to download the source code of 3.0.3 and compile everything to get all the features OpenCPN requires. In fact, I ended to fork and compile the OpenCPN first with all its default plugins (including dashboard). There were many problems, but once resolved, tactics_pi compilation was easy (you need opencpn.lib, anyway). Compiled w/ 4.4.0 still works w/ 4.8.0. My few findings were pulled in by tom-r so you should be OK.

@canne Thank you very much for the quick feedback. On my first try, I had installed just the packages wx-common and wx3.0-headers on my Ubuntu 16.04.3 LTS. Now I saw there is a package libwxbase3.0-dev and that worked. In addition, I needed to install libwxgtk3.0-dev, libbz2-dev and zlib1g-dev to make cmake happy.

make install copied everything to /usr/local/. I symlinked the file to the respective /usr/ directories so that the OpenCPN that I installed through the package manager picks up the plugin.

@canne : Thanks for helping out, much appreciated :-) @falko : Sorry, I'm not a real unix nerd (although I know a bit) and I don't have a running environment ... Reading your inital error messages I thought you hadn't set the library path at all/correctly. But missing libraries points into the same direction ... ;-)

I'm happy to read that you solved it, have fun with the plugin. Thomas
