Hi @all pi-users,
I need some help to understand whatīs going wrong here.
What Iīve done?
Raspi 2 with Raspian Jessie (Linux 4.1.15-v7+)
Using Opencpn with self scanned and convertet to *.kap rastercharts
$ sudo apt-get install build-essential cmake gettext git-core gpsd gpsd-clients libgps-dev wx-common libwxgtk3.0-dev libglu1-mesa-dev libgtk2.0-dev wx3.0-headers libbz2-dev libtinyxml-dev libportaudio2 portaudio19-dev libcurl4-openssl-dev libexpat1-dev libcairo2-dev mesa-utils
Step 2: copy the eglext_brcm.h-file to the right Folder
Step 3: git clone http://github.com/seandepagnier/glshim
Step 4: Add the o4.1.1301 package from the ppa
I can run glxgears (img glxgears1) with 150 fps (in small window)
glxinfo giveīs the output shown in img. glxinfo 1 to 3 (Iīm not able to insert a window here
When I run opencpn with the LD_LIBRARY.... it works without setting OpenGL acceleration.
But in the console window I can get the informations shown in img owopgl. The performance is very much better then using opencpn 4.0
Switching OpenGL on the sreen turns into white (only the red chart frames are shown) When zooming out enough the green world chart is shown.
Switching the options (texture Caching etc.), rebuild
data in the Charts menue havo no visible effects.
In the console window I can see the errors listed in img owithopgl.
When I install the opencpn package without first try to install the glshim then naturally the OpenGL-Option does not work but the performance without this Option will be the same as when using opencpn with the shim.
Iīm sure that thereīs a problem with a library or with a driver, but I donīt know where to start or search.
Can somebody teaches me a little bit
