This post might be helpful for those who are struggling to get Panthera working on systems without NVIDIA cards, and perhaps, more particularly with systems that have Intel HD Graphics cards. In this case, you might be trying to use GLSL option and may be encountering error related to GLSL compilation error or wrong version number. I recently tried to install Panthera Free on a modest laptop configuration (Dell Latitude E6430 running Windows 7 64-bit on i5-3380M with 8GB RAM and Intel HD Graphics 4000) and noticed that the visualizer would not start due to the previously mentioned errors. I could not find a resolution on Cruden website, so I thought I will share my learning for benefit of others.
When using Panthera on laptops with Intel HD graphics cards (no NVIDIA), the visualizer does not startup. (Using "Start Panthera Free" button on "Cruden Session Manager Lite").
Get error message indicating wrong GLSL version number and compilation error.
The issue is caused due to the fact that Intel HD graphics card work with older version of the shader.
The compilation of .glsl files will typically fail when using the defult version number as specified
in the installation (#version 420 for Panthera release in 09/16).
1. Open explorer and search for all *.glsl files in C:\Cruden\Panthera\data\renderer
2. Open all files in Textpad (or such editor)
3. Do a search and replace of all "#version 420" with "#version 150"
4. Save all files and exit editor
5. Restart Cruden Panthera (and hopefully it should work now).
The version number to which the downgrade needs to be done may depend on the OpenGL installations on the user system.
Hope this helps,
