Installation

Most probably it can only be compiled and run on Linux.

sudo apt install libsdl1.2-dev xorg-dev
./configure
make clean
make

To run, this worked with the SD image containing NextZXOS 2.09:

./zesarux  --nosplash --quickexit --def-f-function f4 reset \
     --disablerealjoystick --no-native-linux-realjoy \
    --joystickemulated kempston \
    --frameskip 1 \
    --zoom 1 \
    --enable-divmmc-ports --enable-mmc \
    --mmc-file FULL_PATH_TO_SD_IMAGE
