I encountered this on Fedora 41 which ships Python 3.13. It seems @abdedarghal111 also ran into this on Arch

Seems like pylzma is quite inactive. A kind soul on that project's issue tracker suggested a fix which worked for me:

sudo CFLAGS=-Wno-int-conversion python3 setup.py install

I just tried it on Python 3.13, and it seems broken with that.

Did you try the workaround I posted in the previous comment? I successfully built and used edl from source last week with Python 3.13.1 (Fedora 41 distro package) with that One Weird Trick 🤷

I found out that my board's EMMC died, and it seems unrelated to edl.
And no, I did not need your workaround to build at all on Arch Linux.

If the eMMC actually failed you should be able to ascertain that by using EDL. Just run it verbose and get the 532 extended CSD bytes.
