I've been searching through existing threads and the OpenCPN
website for answers to these issues to no avail.
1. Does OpenGL hardware
support work on the Pi2? Whenever I click that option the charts
go blank even after rebuilding the chart database.
There was some talk of such things being possible such as:
"The OpenGL to OpenGLes translation is already built in to OpenCPN
(GLshim), if I understand correctly it is also used by OpenCPN
So I tried the instructions I found at Building and installing on Cubieboard 2 with HW acceleration | Official OpenCPN Homepage
for the Cubieboard to see if I could get GLshim installed.
But that seems to have led me down a dark path and the OpenCPN
build no longer succeeds which seems strange because it has succeeded before using the instructions on the Pi Chart website. Why they would be different is a mystery to me unless just building and installing GLshim somehow causes the OpenCPN build to behave differently.
The error is apparently in "Linking CXX executable opencpn" and is as follows:
/usr/bin/ld: cannot find -lEGL
Any help or clues would be greatly appreciated. I've been at this for hours, days even.
I've installed and run RPIGears and get between 387 and 403 FPS.
