Hi Everyone, The patch to work around the failed compile is located at https://github.com/weidai11/cryptopp/issues/1094#issuecomment-1035656572 . The patch is against Crypto++ 8.6.
The patch was tested in a Debian Unstable QEMU/Chroot for armel and armhf. It tested Ok. The changes in the diff will be part of Crypto++ 8.7. We should be releasing Crypto++ 8.7 within the next 15 days or so. I plan on early March 2022. Jeff
