This is somewhat off-topic since it doesn't pertain to anything LVGL-specific, but I would piggyback on this line of the Makefile and prepend something like window.buildTimestamp = \"$(shell date)\"; to the echo string.

thanks for help，I have a new qusetion now,If I change the limited size to 1920*1080,I will get lots of mem error,what should I do to avoid this?

Are you referring to the screen resolution? You would need to increase the maximum allowed size in lv_conf.h.

yes I did ,but it shows that
LINK build/index.html
wasm-ld: error: initial memory too small, 22014176 bytes needed
emcc: error: failed (1)
Makefile:52: recipe for target 'build/index.html' failed

What values did you increase it to? It's asking for 20GB of RAM! 😕

I only change the lv_conf.h with
#define LV_HOR_RES_MAX 1920
#define LV_VER_RES_MAX 1080

I did the calculation wrong; it's actually only asking for 20MB, which is much more reasonable. Try adding -s INITIAL_MEMORY=67108864 beside the other -s argument on lines 49 and 53.
