Attempted to do that just now (sorry, I can't believe I didn't try that before??) but it seems that no package of that name (libSDL2_image-2.0.so.0 OR libsdl2-image-2.6.3; I tried both) exists. I did a search and the closest apt package I found in said search is libsdl2-image-2.0-0
I attempted to install that, and it installed successfully- but I'm still getting the same error when attempting to run from the command line. I attempted to update apt packages just to make sure everything is up to date, and it looks like everything is
edit to add an update: I managed to solve that issue by installing the package listed in this GitHub thread. With that solved, though, a new issue pops up as follows. Apologies for the janky formatting, I can't figure out how to format it in a code block within an itch comment:
libcyaml: ERROR: Load: Missing required mapping field: uitxt_F5
libcyaml: ERROR: Load: Backtrace:
libcyaml: ERROR: in mapping field 'uitxt_content' (line: 88, column: 16)
cyaml_load_file error: Missing required mapping field
[1] 37121 segmentation fault (core dumped) ./ChronoScope
At first, libcyaml wasn't installed. But I installed all 3 available libcyaml packages and get the same error.
update 2: added some dummy text at the very bottom of config.yaml for uitxt_F5 and uitxt_saved (both of which, when missing, it crashes without on my device.) The new output is this:
config loaded ok
birth.tm_year: 123
now: 2025/Aug/24 (Sun) 19:14:03
[1] 38364 segmentation fault (core dumped) ./ChronoScope
From here I have no idea how to debug further, but hopefully this speeds it up for you.
