Would be interested to see how > much bigger the library part are. last i checked the esp32's come with something like 512kb ram or so. you can add external dram and i think this maxes out at 4m or 8m or so (i don't know about the new riscv ones). i really don't think you'll get enough of an os base + services + efl lib binaries + even super basic theme data + enough heap to make a useful program into that footprint. a hello world alone will probably exceed that if you did a huge amount of stripping. just some numbers for dependencies (sizes on arm64 here but i might assume ballpark-wise it's not a lot smaller on an esp32 in the end): 1. a libc (dietlibc is still going to be like 1m or so) 2. libjpeg 500k 3. zlib 150k 4. libpng 360k 5. openssl 2m + 14m (libcrypto) so there alone we're at 28m. not including an "os core" like filesystem and other core utility code. i haven't even started putting in bits of efl :) -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - ras...@rasterman.com _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
