hi, here is make output:

$ make
gcc  -lX11 -lpthread  main.c -o xdg-open-server
main.c: In function ‘main’:

https://github.com/kitsunyan/xdg-open-server/blob/master/Makefile#L18 -> $(CC) $(CFLAGS) $(LDFLAGS) $< -o $@ -lX11 -lpthread

And docker command shoule be:

docker run --name my_container \
  -v "${XDG_RUNTIME_DIR}/xdg-open-server:${XDG_RUNTIME_DIR}/xdg-open-server:ro" \
  -v /usr/local/lib/xdg-open-server/xdg-open:/usr/bin/xdg-open:ro \
  -v /bin/socat:/bin/socat \
  my_image

Please start a new terminal and run /usr/local/bin/xdg-open-server before running docker command to init ${XDG_RUNTIME_DIR}/xdg-open-server.
