libpyqt5_py2.so not accepted in Raspberry PI4

EMBED_TAB_NAME= qtscreen
EMBED_TAB_COMMAND= halcmd loadusr -Wn qtvcp_embed qtvcp -d -c qtvcp_embed -x {XID} cam_align

result is a blank tab "qtscreen" in AXIS

I'm sure you will need to compile a version for the rasberry pi.
All the supplied versions are X86 based.

is there also an insider tip, please?
where and how to start?

Sorry, this is Kurt's writeup about what we found out to do for x86:

thanks Chris, that seems interesting for adjustment, Peter
