tool. OpenCPN is developed by a team of active sailors using real
world conditions for program testing and refinement.
-wxGTK3 is a required dependency, however you can use wxGTK or
-wxPython instead if you prefer. If decide to use wxGTK you will
-have to recompile wxGTK with the --enable-graphics_ctx option
-because it is not enabled in the default slackbuild and is
-required by opencpn. The --enable-graphics_ctx option is enabled
-by default in the wxGTK3 and wxPython slackbuilds.
+If you are upgrading or installing new, OpenCPN 5.x now requires
+that wxGTK3 be built with webkitgtk support. So you will have to
+install webkitgtk available here at SBo, then build and install
+wxGTK3.

+OpenCPN only looks for plugins in the "lib" directories. So on
+x86_64 we have to pass an environment variable to use plugins.
+The menu launcher will automatically set this for you, however
+if you choose to launch OpenCPN from the command line you must
+launch it with this command to get plugin support on x86_64.
