Compiling a Qt app for Kobo seems to be more challenging than it used to be:
User Szybet documented the process:
https://github.com/Szybet/nickel-qt-...main/README.md
* Since build process at
https://github.com/Aryetis/qt5-kobo-platform-plugin was broken when last I checked, may need to compile plugin as Qt app as in:
https://github.com/Szybet/niAudio/bl...bo/qt-setup.md
Until somebody takes on that task, you can (* try to * - only tested on Clara HD, though versions of fbkeyboard/fbpad compiled to shared fbink lib are provided in
https://www.mobileread.com/forums/sh...7&postcount=12 ) play with:
https://www.mobileread.com/forums/sh...62&postcount=8
* Not to imply that it couldn't be done in Rust, Python, Golang, Rmkit, or Koreader toolkit etc...
https://www.mobileread.com/forums/sh...74&postcount=4
But how many of these platforms have been updated to the newest devices? Just fbink/Koreader?
May require a dev with a device (or a dev and a user with a device.able to help with testing)

Here's a simple chess game to try.
Use similar build steps as for PONG ON SDL ON SIXEL ON YAFT ON KOBO CLARA:

https://sourceforge.net/projects/mpchess/
$ wget
https://downloads.sourceforge.net/pr...s-1.2.1.tar.gz
$ tar zxvf mpchess-1.2.1.tar.gz
$ cd mpchess-1.2.1/
$ cd src/
$ source ~/koxtoolchain/refs/x-compile.sh kobo env bare
$ mkdir include
$ cp ../../libsixel-1.8.6/include/sixel.h include/
$ mkdir include/SDL
$ cp ../../SDL1.2-SIXEL-sixel/include/*.h include/SDL/
$ mkdir lib
$ cp ../../libsixel-1.8.6/src/.libs/libsixel.a lib/
$ cp ../../libsixel-1.8.6/src/.libs/libsixel.so.1.0.6 lib/libsixel.so.1
$ cp ../../SDL1.2-SIXEL-sixel/build/.libs/libSDL.a lib/
$ cp ../../SDL1.2-SIXEL-sixel/build/.libs/libSDL-1.2.so.0.11.4 lib/libSDL.so
$ cp ../../SDL1.2-SIXEL-sixel/build/.libs/libSDL-1.2.so.0.11.4 lib/libSDL-1.2.so.0
(Actually, all necessary files were included in files attached to Posts #19 and #20 of Crosscompile a web browser for the KOReader terminal
https://www.mobileread.com/forums/sh...d.php?t=350054 )
$ nano -l chess.c
Code:
...
26 #include <SDL/SDL.h>
...
$ nano -l makefile
Code:
1 mpchess: chess.o
2 arm-kobo-linux-gnueabihf-gcc -o mpchess -Llib -lSDL -lm chess.o
3
4 chess.o: chess.c
5 arm-kobo-linux-gnueabihf-gcc -g -Iinclude -c chess.c
6
7 clean:
8 rm -f mpchess chess.o
$ make
$ file mpchess
mpchess: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.33, with debug_info, not stripped
On the desktop you would have compiled with corresponding versions of gcc and libs, and run in a sixel- enabled terminal like:
$ xterm -ti vt340
But on Kobo, you can run in Yaft, but you will need a keyboard like fbkeyboard2 (mentioned above), unless you run from SSH.
Copy the libsixel.a, libsixel.so.1, libSDL.a, and libSDL-1.2.so.0 libs to the /mnt/onboard/.adds/kordir/libs/ folder of your kobo.
Copy the mpchess binary to the /mnt/onboard/.adds/kordir/ folder on the Kobo:
To set the path and library path as in Post #14:
# . /korenv.sh
Run yaft terminal, leaving space for keyboard:
# YAFT_PERCENT=58 yaft
# . /korenv.sh
From a YAFT terminal:
# mpchess
Whoa, everything is tiny - that's a nice project to work on (for someone else
)
Had to pkill mpchess from a separate session.

*UPDATE - A couple of ugly hacks to make it bigger (* new one is mpchess-build.zip, not mpchess.zip)
Inexplicably, I always have to turn on networking, start USB networking, start Dropbox server, then Yaft terminal, then Oskansi2 keyboard, THEN korenv.sh and mpchess, to get reliable operation...
