ah, sorry, the default engine path assumes a 64 bit platform and I didn't consider arm still supports 32 bit systems.  I can fix that shortly.  You can work around it in the interim by modifying the systemd unit file such that the ExecStart line contains the following option:

-o pkcs11:engine_path:/usr/lib/opensc-pkcs11.so

also, since I don't have a raspberry pi handy, can you please post the output of uname -a here so I know what to key off of to modify the default engine path?  Thanks!

Thanks, this is the uname output of my RaspberryPi 2:

# uname -a
Linux pi 5.4.7-200.fc31.armv7hl #1 SMP Tue Dec 31 23:06:32 UTC 2019 armv7l armv7l armv7l GNU/Linux

Thank you!

I've enabled autoconf to set the default engine path based on 32/64 bit guessing during configuration.  The upstream branch is here:
https://github.com/nhorman/rng-tools/tree/default-pkcs11

Would you mind cloning that branch and building rng-tools from it?  Based on your uname output, this should set the default engine path to /usr/lib/opensc-pkcs11.so, which should allow you to work by default.  If rngd runs properly with that change, I'll commit it and backport it to Fedora asap.

ping?

I applied this patch to the rawhide RPM:
https://github.com/nhorman/rng-tools/commit/1993eca9a2d75d1724ba96fbdabd78b29cca9472.patch

But I'm still getting the same error:

can you attach the config.log file from your build effort above please?  I'm in the process of setting up a 32 bit arm VM so I can try reproduce this, but your log might give me a clue before thats complete

ah, thank you, I think i see the problem.  I've pushed another commit to the upstream branch.  Please try rebuilding with that, and the right library should be selected

Latest commit fdd29dc3d01ae2c27e390508518a5ec085b56510 has removed the error:

awesome, I'll merge the upstream branch and backport shortly
