Hi, I'm getting the above weird error when I call make.

I'm using: ./configure --host=aarch64-v8a-linux-gnu --prefix=/home/udl/test --enable-tctienvvar make

Do you have any idea why I am facing this issue?

thanks!

I turned off Werror, and installed the program.

However, I end up getting the following runtime error while using the engine

./openssl rsa -engine tpm2tss -inform engine -in mykey -pubout -outform pem -out mykey.pub
engine "tpm2tss" set.
writing RSA key
double free or corruption (out)
Aborted

However, tpm2tss-genkey -a rsa -s 2048 mykey and openssl rand -engine tpm2tss -hex 10 seem to work just fine

What's your exact openssl version ? I know you are running some 1.0.2something. We need >1.0.2g.

P.S. You sould maybe upgrade to 1.1.1, since support for 1.0.2 is ending...

Thanks a lot! I shall upgrade my OpenSSL version and update you again.

Thanks so much! Upgrading my OpenSSL to 1.0.2u worked.
