Hi Ernst,

I had no problems following your Howto and successfully compiled and installed on a 4y old PC Intel i3 with 8GB RAM running Ubuntu 16.03LTS 64bit with a NVIDIA  GT1030 graphics card (proprietary NVIDIA drivers).

markus@galilei:~/EMCV$ file EUMETCastView
EUMETCastView: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=68d62707a361ddc52f5b95a9fab90484c330f92f, not stripped

runs perfectly smooth and fast, no visible GL errors with the globe.

Hi all,

thanks for all your valuable information and your EUMETCastView compilation HowTo!

Everything went very well, using EUMETCastView v1.4.7; I successfully compiled the software on Debian 10 and Xubuntu LTS (more details below).

*** BUT: Here's my Problem ***
Unfortunately, I don't get the 3D Globe to work. It will show green text: around "60 paintGL calls / s", and after activation of the ground station info also these "Maspalomas, Lannion" etc etc. It also lets me choose segments, but I have no Globe and no background (corona).

I tried it on different hardware:
- hp pavilion dv7 6c40ez (CPU: Intel Core i7-2670QM, 2,2GHz, 4 cores - GPU: AMD Radeon HD 7470M)
- ASUS K56CB (CPU: Intel Core i7-3537U, 4 cores - GPU: NVIDIA® GeForce® GT 740M)
- Intel NUC D54250WYK (CPU: Intel Core i5-4250U 1.3GHz, 2 cores - GPU: Intel® HD-Grafik 5000)

Furthermore, I tried it on the Intel NUC using Windows 10 and the latest v1.4.7 .exe, which works fine, including 3D globe. So HW works.

Now I'm trying to get it to work on the Intel NUC, using Xubuntu 18.04.3 LTS.

*** But Here's The Problem.... ***
When I start EUMETCastView from the terminal, choose the 3D globe menu, it outputs:

*** May you help me? ***
On the ASUS laptop, I tried to install other Linux graphics drivers using (in dir. /usr/bin):
wget -Nc smxi.org/sgfxi && chmod +x sgfxi && sgfxi

Do I need to change something in the source code, so that it will let me use the GLSL 3.30?

Thank you a lot in advance for your assistance, it's very much appreciated!
