OQS OpenSSL build error issue on Ubuntu 22.04

[jingyosong]

hello. I am a researcher applying post quantum cryptography to protocols.

I have a question because an error occurred while building OQS OpenSSL on Ubuntu 22.04.

I first installed liboqs as described in the build guide for OQS OpenSSL.
After that, I tried to install OQS OpenSSL with the command (make -j), but I keep getting the error as below.

error: fatal error: oqs/oqs.h: No such file or directory...

Is there any way to solve this? Thanks for reading.

This typically means that the installation of liboqs didn't wind up in the right location (of oqs-openssl111).

Before diving into this, how long do you want to use this software? openssl111 is nearing its end of life (see https://www.openssl.org/blog/blog/2023/03/28/1.1.1-EOL/) which also means that we will cease to support oqs-openssl111.

Therefore, I'd like to encourage you very much to look at using oqs-provider running as a plugin in OpenSSL3 instead. You can use it ready-built e.g., in this docker image: https://hub.docker.com/repository/docker/openquantumsafe/oqs-ossl3/general

Thank you for answer.

I downloaded OQS OPENSSL first and installed liboqs in its subdirectory. Can you point me to the correct location to install liboqs into oqs openssl directory?
