Regarding OpenGL, this may be of interest and encouraging: ( http://www.raspberryconnect.com/gamessoftware/item/314-trying_out_opengl_on_raspberry_pi_3 ) As for solutions, they aren’t going to walk through the door on their own. And if you do get a problem solved, it does bring along some satisfaction.
There is also a document on how to convert GL applications to GLES that might be useful, and that shows the differences between GL and GLES quite nicely.
Thanks for the reference. My first challenge is to see if I can get just the KiCad executable running. Need to run down the source and some build instructions. I’ve got the newest Raspbian installed. I know these are different applications, but LibreCAD must be relying heavily on OpenGL capabilities. And then the games which place the ultimate demands on graphics. There are a zillion pi 3 boards out there. Me thinks expanding where KiCad can be installed is helpful (to everyone). My hunch is your KiCad 5 will run well on the pi 3. I also may go down in flames trying this. One won’t know until some effort is put into it.

I don’t think it is a great idea, but it worked for me.
@Muniac I have the Pi B+ I think it is; it is not very old. It has a decent SD card in it, an Amplim 32G class 10. Loaded onto the card is BerryBoot and Ubuntu Mate 16.04 and I think this is because Raspbian did not work for some reason. At the time I did this there was an ARM KiCad on the main page, and my RasPi is running KiCad V4.0.2 according to the help window.
I just tried all 3 graphics modes, and OpenGL seemed to work reasonably well in PcbNew. If V5 were compiled for the RasPi I would expect similar results.
Thanks for diving into this. It’s good information. I did try Ubuntu 16.04 with no luck on my pi 3 model B trying to install KiCad V5. I think the program can/will run with acceptable performance. We’ll see as this unfolds. I’m sure I’ll be back with bottlenecks. Take care.

OK - The exercise begins: I’ve downloaded the KiCad V5 source and looking at the build instructions. Some requirements in there that need attention.
- Install wxWidgets being the first challenge.
There isn’t anything ready to go for arm7hf which was expected. So I’m trying to build this from source. ./configure yielded the details below:

Package gtk±2.0 is not found so I’m endeavoring to solve that problem. Running things down 1 at a time hoping to get a clean configure. We’ll see how it goes.

KiCad 5.1 can be configured also for wxWidgets+GTK3. You can try that if GTK2 doesn’t work.
You need to install libgtk2.0-dev or libgtk-3-dev package.
OK I got libgtk installed. Files are below:
libgtk-3.so.0 - Sym link
libgtk-3.so - Sym link
Configure is still complaining: Package gtk±2.0 was not found in the pkg-config search path.
Does anyone know the exact name of the file configure is looking for so I can create a symbolic link to it? I don’t think it’s the search path as other libraries are found. Many thanks for the assistance.
Maybe libgtk-2.so ??

You need to install sources, not just library. If you note in my post I have
xxxx-dev packages, those are the ones that install sources. Without them you can’t compile wxWidgets.
Raspbian is sufficiently similar to Debian that you should get by with the building instructions from the Debian download page.
qu1ck - I did install the libgtk-3-dev package using sudo apt-get install. The install completed without errors. I’m assuming that means everything got installed including the source. “configure” wants to confirm a library which it can’t find. More fundamental is wxWidgets configure is reporting “armv7l-unknown-linux-gnueabihf” (via config.log). This means it doesn’t know where to look for certain files in an unknown architecture. It thus makes assumptions, some correct and others ???. Need to dig more in the wxWidgets camp. I suspect this could be corrected with proper file/directory names. But which ones and what names??
The log shows status on checks for a “toolkit” and reports gtk. It’s also passing gcc a -V option to check on the compiler. -V is unrecognized and it should be -v which returns all the compiler version info. Raspbian gcc is v6.3.0 several versions old. Tons of little missing and/or incorrect details. Any one of which shuts things down.
Gyros - Thanks. KiCad 5 debian complained about a missing package with no details. I used the package installer which isn’t a wealth of details on Raspbian. KiCad 4 seemed to install without problems. I’m able to at least launch the application.
I can post config.log but it’s a monster!
Thanks for ongoing assistance.

Perhaps some progress. It took a good 5+ hours to grind through the wxWidgets make. The make install went much faster. Status reported below:
The installation of wxWidgets is finished. On certain
platforms (e.g. Linux) you’ll now have to run ldconfig
if you installed a shared library and also modify the
LD_LIBRARY_PATH (or equivalent) environment variable.
wxWidgets comes with no guarantees and doesn’t claim
to be suitable for any purpose.
Read the wxWindows Licence on licencing conditions.
Despite some errors it appears this got installed. More work to be done.
So does virtually any software ever made. That’s just legalese for “take it or leave it, don’t sue me either way”.
I think that was the message from wxWindows, not from Muniac…
Yes the disclaimer was from “make install”. Pretty standard stuff in a litigious society. I was more concerned about the installation part of the message. Perhaps one requirement checked off for KiCad v5 on the pi. Need to go back and continue with the build instructions. It also seems the v2 libgtk install (instead of v3) solved some other missing file(s) issues. I’ll keep the update coming. Thanks.

Would anyone have a small C program they can post to exercise a few wxWidgets functions. Would help to verify it’s installed and running at some basic level. Thanks.
There is sample program here (full code at the end of the page)
