5 years ago You are right, the sdl2 library for linux has a problem, it is mentioned in the Known problems.
Most probably, due to a mistake in the new build environment, it was compiled without x11 support.
It is on my TODO list, hopefully will be solved during the next days.
As a workaround, you can use the system library.
Description
I wanted to start with STM32 Microcontroller und tried the "blinky" example with GNU MCU Eclipse as destribed here:
All works fine until "Run the test with QEMU". Qemu did not start.
The only output in Eclipse Console was: "GNU MCU Eclipse 64-bit QEMU v2.8.0-5 (qemu-system-gnuarmeclipse)." and over there was a line "< terminated > Test blinky Debug [GDB Qemu Debugging] qemu-system-gnuarmeclipse" There was no error message!
I didn't find the called "command line" in Eclipse, but after some time with google: /home/user/opt/xPacks/@gnu-mcu-eclipse/qemu/2.8.0-5.1/.content/bin/qemu-system-gnuarmeclipse --verbose --verbose --board STM32F4-Discovery --mcu STM32F407VG --gdb tcp::1234 -d unimp,guest_errors --semihosting-config enable=on,target=native --semihosting-cmdline blinky failed with error message: GNU MCU Eclipse 64-bit QEMU v2.8.0-5 (qemu-system-gnuarmeclipse). Unable to initialize SDL: No available video device
But there is a video device! After renaming opt/xPacks/@gnu-mcu-eclipse/qemu/2.8.0-5.1/.content/bin/libSDL2-2.0.so.0 (to _libSDL2-2.0.so.0) qemu used the system wide sdl library (OpenSuse Leap 15) and qemu works!
I think there is a bug with sdl library coming with qemu xpacks.
Steps to Reproduce
I installed GNU MCU Exlipse and other software as recommendet in the "blinky" example: https://gnu-mcu-eclipse.github.io/install/
I used xpm to install gcc, build tools, openocd and qemu.
