I can't attach the log, so I'll paste it here:

Comment 2 by Grégory Soutadé, Jan 8, 2023
Hi Francesco, Which version of OpenSSL are you running ? I made some changes in order to build using OpenSSL 3.
Comment 3 by Francesco Turco, Jan 9, 2023
I have openssl-1.1.1s on Gentoo Linux since I'm using the stable repository (amd64). OpenSSL 3 belongs to the testing repository (~amd64), which I prefer to avoid at this moment. On my only other computer I run Void Linux, which also uses openssl 1.1.1s currently.
Comment 4 by Grégory Soutadé, Jan 9, 2023
OK. The support for this version of OpenSSL will end in september 2003. Since that, you have to use libgourou v0.7.1.
Comment 5 by Francesco Turco, Jan 10, 2023
I upgraded OpenSSL to version 3.x on Gentoo, and now I'm able to build and use libgourou successfully. Thank you!
