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

Or, maybe try one pre-compiled for Raspberry Pi.

thank you Scott, unfortunately it did not help yet!

it says still

'/usr/lib/arm-linux-gnueabihf/qt5/plugins/designer/libpyqt5_py2.so' is an invalid ELF object (wrong CPU architecture)

should we find a suitable libpyqt5_py2.so may be?

Hi cmorley,

I am working on a RPi4.
I manage to build and run Qt5/PyQt5 from source but I get the following:
 
 

Where can I find the libpyqt5_py2.so pluging binary for RPi4?
If not, where can a find the source and build instructions to build a brand new libpyqt5_py2.so plugin for RPi4?

I think it is a platform conflict, so it seems making a rebuild for RPi could be work. 

Thanks!
