A noted on the opencpn
.org Downloads page ( you do read that occasionally, don't you?
Version 4.1.x for Windows and linux
requires a complete new set of PlugIn builds to support wxWidgets 3.0.
This is a little disruptive, I know. But it is an occasionally necessary thing as our underlying wxWidgets libraries evolve and we want to take advantage of the upstream improvements in those libraries.
nohal (pavel) is maintaining a table of the current
state and URL links of the various PlugIns at:
Plugins for OpenCPN 4.1 | Official OpenCPN Homepage
Most of the popular PlugIns have been converted and built for the new libraries, and are available for download now. If you have not updated your PlugIns for Beta 4.1.x, you may wish to do so now.
Please note that the new build PlugIns are not
compatible with OpenCPN V4, so you may wish to use a parallel installation
of the Beta releases to avoid breaking a working O4 installation
that you depend on.
Thanks for your support
