Compile OpenVPN 2.5.7 in Amazon Linux 2023

[sharons]

Hi,

I'm trying to compile OpenVPN 2.5.7 in Amazon Linux 2023.

running ./configure fails with:

checking additionally if OpenSSL is available and version >= 1.0.2... configure: error: OpenSSL version too old

However: "rpm -qa | grep openssl" gives:

openssl-3.0.8-1.amzn2023.0.7.x86_64
openssl-pkcs11-0.4.12-3.amzn2023.0.1.x86_64
openssl-libs-3.0.8-1.amzn2023.0.7.x86_64

Quoting from https://openvpn.net/community-downloads:

"The OpenVPN community project team is proud to release OpenVPN 2.5.7. This is mostly a bugfix release, but adds limited support for OpenSSL 3.0. Full support will arrive in OpenVPN 2.6."

So it makes sense to expect to be able to compile successfully.

Thanks a lot for your help,
Sharon
